This is a major release of DBD::ODBC with major advancements in unicode handling and a plethora of other changes. Please see below for a list of changes since 1.16. Thanks to all who contributed and as always to cpan-testers. =head2 Changes in DBD::ODBC 1.17 September 22, 2008 In the absence of any bug reports since 1.16_4 this is the official 1.17 release. See below for changes since 1.16. Minor pod changes. =head2 Changes in DBD::ODBC 1.16_4 September 12, 2008 Small change to Makefile.PL to work around problem in darwin 8 with iODBC which leads to "Symbol not found: _SQLGetPrivateProfileString" errors. Added new [n]varXXX(max) column type tests to 20SqlServer.t. Fixed support for SQL_WCHAR and SQL_WVARCHAR support in non-unicode build. These types had ended up only being included for unicode builds. More changes to ODBC pod to 1) encourage people to use CPAN::Reporter, 2) rework contributing section, 3) mention DBIx::Log4perl 4) add a BUGS section 5) add a "ODBC Support in ODBC Drivers" section etc. Changed default fallback parameter bind type to SQL_WVARCHAR for unicode builds. This affects ODBC drivers which don't have SQLDescribeParam. Problem reported by Vasili Galka with MS Access when reading unicode data from one table and inserting it into another table. The read data was unicode but it was inserted as SQL_CHARs because SQLDescribeParam does not exist in MS Access so we fallback to either a default bind type (which was SQL_VARCHAR) or whatever was specified in the bind_param call. Fixed bug in 20SqlServer.t when DBI_DSN is defined including "DSN=". =head2 Changes in DBD::ODBC 1.16_3 September 3, 2008 Changed Makefile.PL to add "-framework CoreFoundation" to linker line on OSX/darwin. Disallow building with iODBC if it is a unicode build. More tracing for odbcconnect flag. Fix bug in out connection string handling that attempted to use an out connection string when SQLDriverConnect[W] fails. Fixed yet more test count problems due to Test::NoWarnings not being installed. Skip private_attribute_info tests if DBI < 1.54 About a 30% rewrite of bound parameter code which started with an attempt to support the new VARBINARY(MAX) and VARCHAR(MAX) columns in SQL Server when the parameter length is > 400K in size (see elsewhere in this Changelog). This is a seriously big change to DBD::ODBC to attempt to be a bit more clever in its handling of drivers which either do not support SQLDescribeParam or do support SQLDescribeParam but cannot describe all parameters e.g., MS SQL Server ODBC driver cannot describe "select ?, LEN(?)". If you specify the bound parameter type in your calls to bind_param and run them to an ODBC driver which supports SQLDescribeParam you may want to check carefully and probably remove the parameter type from the bind_param method call. Added rt_38977.t test to test suite to test varchar(max) and varbinary(max) columns in SQL Server. Moved most of README.unicode to ODBC.pm pod. Added workaround for problem with the Microsoft SQL Server driver when attempting to insert more than 400K into a varbinary(max) or varchar(max) column. Thanks to Julian Lishev for finding the problem and identifying 2 possible solutions. =head2 Changes in DBD::ODBC 1.16_2 September 2, 2008 Removed szDummyBuffer field from imp_fbh_st and code in dbd_describe which clears it. It was never used so this was a waste of time. Changed the remaining calls to SQLAllocEnv, SQLAllocConnect and SQLAllocStmt and their respective free calls to the ODBC 3.0 SQLAllocHandle and SQLFreeHandle equivalents. Rewrote ColAttributes code to understand string and numeric attributes rather than trying to guess by what the driver returns. If you see any change in behaviour in ColAttributes calls you'll have to let me know as there were a number of undocumented workarounds for drivers. Unicode build of DBD::ODBC now supports: =over =item column names The retrieval of unicode column names =item SQL strings Unicode in prepare strings (but not unicode parameter names) e.g., select unicode_column from unicode_table is fine but select * from table where column = :unicode_param_name is not so stick to ascii parameter names if you use named parameters. Unicode SQL strings passed to the do method are supported. SQL strings passed to DBD::ODBC when the odbc_exec_direct attribute is set will B<not> be passed as unicode strings - this is a limitation of the odbc_exec_direct attribute. =item connection strings True unicode connection string support will require a new version of DBI (post 1.607). B<note> that even though unicode connection strings are not supported currently DBD::ODBC has had to be changed to call SQLDriverConnectW/SQLConnectW to indicate to the driver manager it's intention to use some of the ODBC wide APIs. This only affects DBD::ODBC when built for unicode. =item odbcunicode trace flag There is a new odbcunicode trace flag to enable unicode-specific tracing. =back Skipped 40Unicode.t test if the ODBC driver is Oracle's ODBC as I cannot make it work. Changes internally to use sv_utf8_decode (where defined) instead of setting utf8 flag. Fix problems in the test when Test::NoWarnings is not installed. Removed some unused variables that were leading to compiler warnings. Changed a lot of tracing to use new odbcconnection flag Changed to use dbd_db_login6_sv if DBI supports it. Commented out a diag in 20SqlServer.t that was leading to confusion. Added diag to 20SqlServer.t in mars test to explain why it may fail. Various pod changes for clarification and to note odbc_err_handler is deprecated. Removed odbcdev trace flag - it was not really used. New odbc_out_connect_string attribute for connections which returns the ODBC driver out connection string. =head2 Changes in DBD::ODBC 1.16_1 August 28, 2008 Fixed bug in odbc_cancel which was checking the ACTIVE flag was on before calling SQLCancel. Non-select statements can also be cancelled so this was wrong. Thanks to Dean Arnold for spotting. Minor changes to test 01base to attempt to catch install_driver failing, report it as a fail and skip other tests. Fixed bug reported by James K. Lowden with asynchronous mode and SQLParamData where the code was not expecting SQL_STILL_EXECUTING and did not handle it Added odbc_putdata_start attribute to determine when to start using SQLPutData on lobs. Fixed bug in lob inserts where decimal_digits was being set to the size of the bound lob unnecessarily. Minor change to connect/login code to delete driver-specific attributes passed to connect so they do not have to be processed again when DBI calls STORE with them. New 12blob.t test. A lot of code tidy up but not expecting any real benefit or detriment when using DBD::ODBC. Fixed retrieving [n]varchar(max) columns which were only returning 1 byte - thanks to Fumiaki Yoshimatsu and perl monks for finding it. See http://markmail.org/message/fiym5r7q22oqlzsf#query:Fumiaki Yoshimatsu odbc+page:1+mid:fiym5r7q22oqlzsf+state:results Various minor changes to get the CPANTS kwalitee score up. fixed pod issues in FAQ.pm moved mytest dir to examples added generated_by and requires perl version to META.yml added pod and pod-coverage tests removed executable flag from Makefile.PL added use warnings to some modules and tests fixed pod errors in ODBC.pm added AUTHOR and LICENSE section to ODBC.pm added Test::NoWarnings to tests Added support for setting the new(ish) DBI ReadOnly attribute on a connection. See notes in pod. Changes to test suite to work around problems in Oracle's instant client 11r1 ODBC driver for Linux (SQLColAttributes problems - see 02simple.t). New tests in 30Oracle.t for oracle procedures. Martin -- Martin J.

I call it Camelbox. Along with all of the GTK stuff, you can install the DBI and DBD::[Pg|mysql|ODBC|SQLite] modules (including all of the binaries needed for those modules), and has the basic functionality of the included DBI/DBD stack tested for each release. I don't really have any plans at the moment to add other databases, not because I don't want to, but mostly due to licensing/redistribution issues. I have more information about the project at the Camelbox home page [1], and the release notes for the latest release are in the release announcement on Google Groups [2]. Feel free to post any questions you have about the project on the Google Groups list, and I'll do my best to answer them.

DBI is an open standard application programming interface (API) that provides database access for client applications written in Perl. DBI defines a set of functions, variables, and conventions that provide a platform-independent database interface. The DBD::DB2 driver works with DBI and a DB2 client to access databases. **New In Release - Support for Trusted Context to create Trusted Connections. - Also please see the Changelog and README for Installation Caveats.

The focus of this release is to add further unicode support to DBD::ODBC. For full unicode support (namely ODBC connection strings) you will need a DBI from subversion or you'll have to wait for Tim to release it but all other unicode support is not dependent on DBI. A list of changes since the last DBD::ODBC test release is included below. As a reminder, to get full unicode support you will need a unicode aware driver manager (like unixODBC or Microsofts driver manager) and you will need to build DBD::ODBC with the -u switch (e.g., perl Makefile.PL -u). Please let me know if you find any problems as this is probably the most substantial release of DBD::ODBC in years and I'm sure there will be some issues I've not found. If you are too impatient to wait for CPAN you will find a copy here: ftp://ftp.easysoft.com/pub/ =head2 Changes in DBD::ODBC 1.16_2 September 2, 2008 Removed szDummyBuffer field from imp_fbh_st and code in dbd_describe which clears it.

This release contains several fixes, particularly the issue where TAKE_IMP_DATA_VERSION being defined allowed code features to be compiled in that caused potential grief for anyone running DBI < 1.60x (segfault). I've disabled this for the time being until I find a better solution. I've also decided from now on, as soon as I get a patch, or if I fix something, even if it is a minute change, I'm rolling out a release. Release early and often, right!? The changes in this release are: * Multi statement patch (fixes multi statement issues), thanks to Chris Heath! * Disabled TAKE_IMP_DATA_VERSION because segfault with DBI < 1.607 * #29528: bind_param(..., SQL_FLOAT) ignores exponents - fixed, Thanks to Tokuhiro Matsuno! * Cleanups to make mysqlEmb work under Cygwin - Thanks to Chris Rodgers <http://rodgers.org.uk/> ! * Modified and disabled tests for MySQL version < 4.1 for unsupported features Thanks again to Chris Heath, Tokuhiro Matsuno, and Chris Rodgers for their patches as well as to everyone else who was kind enough to report bugs!

Every feature Oracle offers can be accessed via OCI. Including Transparent Application Failover (TAF) and bulk loading. The Oracle::OCI module bootstraps itself at build time. Automatically creating perl interfaces to all the OCI functions in your installed version of Oracle. It lets you write OCI code in perl: OCIHandleAlloc($env, my $dschp, OCI_HTYPE_DESCRIBE, 0, 0); OCIDescribeAny($dbh, $dbh, oci_buf_len($table), OCI_OTYPE_NAME, 1, OCI_PTYPE_TABLE, $dschp); OCIAttrGet($dschp, OCI_HTYPE_DESCRIBE, my $parmp, 0, OCI_ATTR_PARAM, $dbh, 'OCIParamPtr'); OCIAttrGet($parmp, OCI_DTYPE_PARAM, my $numcols, 0, OCI_ATTR_NUM_COLS, $dbh, 2); OCIAttrGet($parmp, OCI_DTYPE_PARAM, my $collst, 0, OCI_ATTR_LIST_COLUMNS, $dbh, 'OCIParamPtr'); That may seem a little low-level, but that's not the point. This is an enabling technology and what it enables is huge: access to the *entire* Oracle OCI interface. Soon there'd be modules built on top of Oracle::OCI that provide higher-level interfaces to specific areas of functionality, like LOBs, bulk loading, objects, advanced queuing, etc etc. Oracle::OCI also integrates very well with DBI and DBD::Oracle. You can use a $dbh or $sth wherever it would be reasonable to. I've not worked on it since 2001 as I very rarely use Oracle these days. The Oracle::OCI module had moved beyond proof-of-concept but still needs a little love before it's ready for prime-time. Interesting? Interested?

Ticket #32309. Fixed the selectall_arrayref, selectrow_arrayref, and selectrow_array methods that get embedded into compiled drivers to use the inner sth handle when passed a $sth instead of an sql string. Drivers will need to be recompiled to pick up this change. Fixed leak in neat() for some kinds of values thanks to Rudolf Lippan. Fixed DBI::PurePerl neat() to behave more like XS neat(). Increased default $DBI::neat_maxlen from 400 to 1000. Increased timeout on tests to accomodate very slow systems. Changed behaviour of trace levels 1..4 to show less information at lower levels. Changed the format of the key used for $h->{CachedKids} (which is undocumented so you shouldn't depend on it anyway) Changed gofer error handling to avoid duplicate error text in errstr. Clarified docs re ":N" style placeholders. Improved gofer retry-on-error logic and refactored to aid subclassing. Improved gofer trace output in assorted ways. Removed the beeps "\a" from Makefile.PL warnings. Removed check for PlRPC-modules from Makefile.PL Added sorting of ParamValues reported by ShowErrorStatement thanks to to Rudolf Lippan. Added cache miss trace message to DBD::Gofer transport class. Added $drh->dbixs_revision method. Added explicit LICENSE specification (perl) to META.yaml =cut Enjoy!

This release contains the following changes: =head1 CHANGES =head2 Changes in DBD::ODBC 1.16 May 13, 2008 =head3 Test Changes Small change to the last test in 10handler.t to cope with the prepare failing instead of the execute failing - spotted by Andrei Kovalevski with the ODBCng Postgres driver. Changed the 20SqlServer.t test to specifically disable MARS for the test to check multiple active statements and added a new test to check that when MARS_Connection is enabled multiple active statements are allowed. Changed the 09multi.t test to use ; as a SQL statement seperator instead of a newline. A few minor "use of unitialised" fixes in tests when a test fails. In 02simple.t Output DBMS_NAME/VER, DRIVER_NAME/VER as useful debugging aid when cpan testers report a fail. 2 new tests for odbc_query_timeout added to 03dbatt.t. Changed 02simple.t test which did not work for Oracle due to a "select 1" in the test. Test changed to do "select 1 from dual" for Oracle. New tests for numbered and named placeholders. =head3 Documentation Changes Added references to DBD::ODBC ohloh listing and markmail archives. Added Tracing sections. Added "Deviations from the DBI specification" section. Moved the FAQ entries from ODBC.pm to new FAQ document. You can view the FAQ with perldoc DBD::ODBC::FAQ. Added provisional README.windows document. Rewrote pod for odbc_query_timeout. Added a README.osx. =head3 Internal Changes More tracing in dbdimp.c for named parameters. #ifdeffed out odbc_get_primary_keys in dbdimp.c as it is no longer used. $h->func($catalog, $schema, $table, 'GetPrimaryKeys') ends up in dbdimp.c/dbd_st_primary_keys now. Reformatted dbdimp.c to avoid going over 80 columns. Tracing changed. Levels reviewed and changed in many cases avoiding levels 1 and 2 which are reserved for DBI. Now using DBIc_TRACE macro internally. =head3 Build Changes Changes to Makefile.PL to fix a newly introduced bug with 'tr', remove easysoft OOB detection and to try and use odbc_config and odbcinst if we find them to aid automatic configuration. This latter change also adds "odbc_config --cflags" to the CC line when building DBD::ODBC. Avoid warning when testing ExtUtils::MakeMaker version and it is a test release with an underscore in the version. =head3 Functionality Changes Added support for parse_trace_flag and parse_trace_flags methods and defined a DBD::ODBC private flag 'odbcdev' as a test case. Add support for the 'SQL' trace type. Added private trace type odbcdev as an experimental start. Change odbc_query_timeout attribute handling so if it is set to 0 after having set it to a non-zero value the default of no time out is restored. Added support for DBI's statistics_info method. =head3 Bug Fixes Fix bug in support for named placeholders leading to error "Can't rebind placeholder" when there is more than one named placeholder. Guard against scripts attempting to use a named placeholder more than once in a single SQL statement. If you called some methods after disconnecting (e.g., prepare/do and any of the DBD::ODBC specific methods via "func") then no error was generated. Fixed issue with use of true/false as fields names in structure on MAC OS X 10.5 (Leopard) thanks to Hayden Stainsby. Remove tracing of bound wide characters as it relies on null-terminated strings that don't exist. Fix issue causing a problem with repeatedly executing a stored procedure which returns no result-set.

IBM Informix Database Driver for Perl (also known as DBD::Informix) is the driver code that enables Perl 5.6.1 or later to access Informix databases via the DBI module (but if you are not already using Perl 5.10.0 - or any later version - you should be planning to upgrade). You will need the code for DBI version 1.38 or later as well (v1.604 - or any later version - is recommended). The code for DBD::Informix is available for download via: http://www.perl.org/CPAN/modules/by-category/07_Database_Interfaces http://dbi.perl.org/ ** When you successfully build this module, use the ItWorks (Perl) ** script to report your configuration to the maintenance team (meaning ** Jonathan Leffler) at dbd.informix@gmail.com. ** The ItWorks script does not send email to anybody; you have to do ** that yourself. New in release :PRODVER:: * Fix $sth->{TYPE}: return 9 (SQL_DATE) not -1 (SQL_LVARCHAR), fixing an 11-year old bug. * Add support for BIGINT in ESQL/C 3.50, including $h->{ix_bigserial}. * CPAN Testers reporting issues because Makefile.PL not exiting successfully when pre-requisites not met. * ESQL/C 3.50 (for IDS 11.50) typedefs ifx_loc_t - update dumpesql.h to cope (Joe R Plugge <jrplugge@west.com>). * ESQL/C test fails during configuration when $Config{ccflags} has leading spaces. Records show this problem also affected Dr Guenther Seifert <guenther-h.seifert@t-systems.com> in June 2007. Apologies for not getting it fixed sooner. Release 2008.0229: * RT#32975: Add $h->{ix_serial} and $h->{ix_serial8}. Release 2007.0914 * RT#29364: Fix problem identifying ESQL/C libraries.

This release contains the changes: * Took out mysql_server_init call where not needed * Complete re-write of test suit to use Test::More - tons of cleanups! * Makefile.PL changes to use current user in 'make test' if not defined The biggest change in this release is a completely re-written test suite now using Test::More. This was something I wanted to do for at least two years. Using Test::More for the test suite makes it so much easier to add, manage and understand the various tests that come with the driver.

I have released version 0.11 to CPAN and it should appear soon. This version includes the following changes: DBIx::Log4perl did not support the use of statement handles returned as output bound parameters in DBD::Oracle because it had not seen them created and hence had not injected the log handle into them. DBIx::Log4perl was changed to only retrieve Oracle dbms_output if the logging handle has debug enabled but unfortunately it was continuing to enable dbms_output regardless of logging mode. As a result, once dbms_output was enabled, the Oracle dbms_output buffer starts filling and once full your procedures die. DBIx::Log4perl no longer sets $Log::Log4perl::caller_depth to 2 in the BEGIN because the depth depends on the method you are in. Instead Log::Log4perl::caller_depth is set in each method. Database methods and statement methods are now logged with one or more numbers (in brackets) indicating which connection or statement handle is being used. e.g., DEBUG - connect(0): DBI:CSV: DEBUG - connect(1): DBI:CSV: DEBUG - connect(2): DBI:CSV: DEBUG - do(0): 'drop table fred' DEBUG - prepare(0.3): 'insert into fred (id, name) values(?,?)' DEBUG - $execute_array(0.3) = [undef,1,'one']; DEBUG - $bind_param_array(0.3) = [1,1]; DEBUG - $bind_param_array(0.3) = [2,'one']; DEBUG - finish(0.3) which shows 3 connections numbered 0, 1 and 2 and the prepare etc methods are all called in connection 0 using statement 3 i.e., where there is one number it is a connection and where there are two e.g., (0.3), the first is the connection and the second the statement. A modest speed up when using DBIx::Log4perl and some categories of logging are disabled. Connect method could use uninitialised dsn/user if they are not set in the connect call e.g. DBI:CSV: Martin -- Martin J.

It is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles, under the auspices of The Pythian Group as open source/free software. The release has been fully tested with the latest version of DBI (1.601). Below is the list of the changes and/or fixes in this release. Changes in DBD-Oracle 1.21(svn rev 11067) 11th April 2008 Added Notes to README.win32.txt on installing Instant Client 1.1.0.6.0from John Scoles Added the oci_typecode_name method to get the name rather than just the number of an OCI_TYPECODE from John Scoles Fixed a unreported bug with Embedded Objects from John Scoles Fixes for #34621 & 33791 from RT cpan Added patch to allow faster fetch from REF CURSORs from Biswadeep Chowdhury Updated the Todo file for next version from John Scoles Added support for the 10.2 Data Interface for Persistent LOBs by John Scoles Changed the way pre-fetching is done by John Scoles Added support for Scrollable cursors from John Scoles Changed the max size of cache_rows to a sb4 rather than a int and or a ub4 from John Scoles Added support for Lobs in select of OCI Embedded Objects from John Scoles with a big thankyou to Paul Weiss Fixed for embedded object in object from Paul Weiss Added support for direct insert of large XML data into XMLType fields from Hendrik Fuss & John Scoles Fixed memory leak (not releasing Temp Lob with OCILobFreeTemporary) when created for a bind from John Scoles Added support for bind_param_inout_array for use with execute_array from John Scoles Added enhancement for Embedded Objects handling from Paul G. Weiss Fixed to Makefile.PL let it read makefiles from other makes from Alexander V Alekseev Updated POD to tell users to Avoid Using "SQL Call" from Charles Jardine Updated POD to account for rt.cpan.org #30910: "DBD-Oracle crashes when trying to read empty LOB" from John Scoles Added DBD::Oracle impdata/threads patch from Jeffrey Klein In this release there are a number of new features. One important one you might want to have a look is support for binding an array for in-out operations with execute_array. Given this sql; INSERT INTO foo (id, bar) VALUES (foo_id_seq.nextval, ?) RETURNING id INTO ? and using execute_array to insert 200 records you will get an array back of the 200 new IDs inserted. I have also added support for direct inserting of large XML files into an XMLType field. Another important addition is support for Persistent LOBs if you are using Oracle 10.2 or later. You can now treat LOBs as if they were any other form of data so say good-by to LOB locators. Finally I have added support for native oracle 'Scrolling Cursors'. There were also a number of bug fixes and code enhancements/updates as detailed above.

The changes in 1.15 (final) and previous development releases are listed below. There are some fairly serious changes in this version compared with 1.14. =head2 Changes in DBD::ODBC 1.15 January 29, 2008 Fixed bug reported by Toni Salomaki where DBD::ODBC may call SQLNumResultCols after SQLMoreResults returns SQL_NO_DATA. It led to the error: Describe failed during DBI::st=HASH(0x19c2048)->FETCH(NUM_OF_FIELDS,0) when NUM_OF_FIELDS was referenced in the Perl script. Updated odbc_exec_direct documentation to describe its requirement when creating temporary objects in SQL Server. Added FAQ on SQL Server temporary tables. Fixed bug in dbdimp.c which was using SQL_WCHAR without testing it was defined - thanks Jergen Dutch. Fixed use of "our" in UCHelp.pm which fails on older Perls. Minor changes to 02simple.t and 03dbatt.t to fix diagnostics output and help debug DBD which does not handle long data properly. Further changes to Makefile.PL to avoid change in behavior of ExtUtils::MakeMaker wrt order of execution of PREREQ_PM and CONFIGURE. Now if DBI::DBD is not installed we just warn and exit 0 to avoid a cpan-testers failure. =head2 Changes in DBD::ODBC 1.15_2 November 14, 2007 Fix bug in DBD::ODBC's private function data_sources which was returning data sources prefixed with "DBI:ODBC" instead of "dbi:ODBC". If you don't have at least DBI 1.21 it is now a fatal error instead of just a warning. DBI->connect changed so informational diagnostics like "Changed database context to 'master'" from SQL Server are available in errstr/state. These don't cause DBI->connect to die but you can test $h->err eq "" after connect and obtain the informational diagnostics from errstr/state if you want them. Fixed problem in 41Unicode.t where utf8 was used before testing we had a recent enough Perl - thank you cpan testers. Changed "our" back to "my" in Makefile.PL - thank you cpan testers. Removed all calls to DBIh_EVENT2 in dbdimp.c as it is no longer used (see posts on dbi-dev). Changed text output when a driver manager is not found to stop referring to iodbcsrc which is no longer included with DBD::ODBC. Changed Makefile.PL to attempt to find unixODBC if -o or ODBCHOME not specified. Updated META.yml based on new 1.2 spec. Changed Makefile.PL so if an ODBC driver manager is not found then we issue warning and exit cleanly but not generating a Makefile. This should stop cpan-testers from flagging a fail because they haven't got an ODBC driver manager. Changed Makefile.PL so if an ODBC driver manager is not found then we issue warning and exit cleanly but not generating a Makefile. This should stop cpan-testers from flagging a fail because they haven't got an ODBC driver manager. Changed Makefile.PL so it no longer "use"s DBI/DBI::DBD because this makes cpan-testers log a fail if DBI is not installed. Changed to put the DBI::DBD use in the CONFIGURE sub so PREREQ_PM will filter out machines where DBI is not installed. Fix a possible typo, used once in 10handler.t. =head2 Changes in DBD::ODBC 1.15_1 November 6, 2007 Minor changes to 20SqlServer.t test for SQL Server 2008 (Katmai). Timestamps now return an extra 4 digits of precision (all 0000) and the driver reported in dbcc messages has a '.' in the version which was not handled. New FAQ entry and test code for "Datetime field overflow" problem in Oracle. Changed all ODBC code to use new SQLLEN/SQLULEN types where Microsoft's headers indicate, principally so DBD::ODBC builds and works on win64. NOTE: you will need an ODBC Driver Manager on UNIX which knows SQLLEN/SQLULEN types. The unixODBC driver manager uses SQLLEN/SQLULEN in versions from at least 2.2.12. Thanks to Nelson Oliveira for finding, patching and testing this and then fixing problems with bound parameters on 64 bit Windows. Added private_attribute_info method DBI introduced (see DBI docs) and test cases to 02simple.t. Fairly major changes to dbd_describe in dbdimp.c to reduce ODBC calls by 1 SQLDescribeCol call per column when describing result sets. Instead of calculating the amount of memory required to hold every column name we work on the basis that (num_columns + 1) * SQL_MAX_COLUMN_NAME_LEN can hold all column names. However, to avoid using a large amount of memory unnecessarily if an ODBC driver supports massive column name lengths the maximum size per column is restricted to 256. Changed to avoid using explicit use of DBIc_ERRXXX in favour of newish (ok, DBD::ODBC is a bit behind the times in this respect) DBIh_SET_ERR_CHAR. This involved a reworking or the error handling and although all test cases still pass I cannot guarantee it has no other effects - please let me know if you spot differences in error messages. Fixed bug in 20SqlServer test for multiple results that was passing but for the wrong reason (namely, that the odbc_err_handler was being called when it should not have been). Fixed bug in odbc_err_handler that prevented it from being reset so you don't have an error handler. Looks like the problem was in dbd_db_STORE_attrib where "if(valuesv == &PL_sv_undef)" was used to detect undef and I think it should be "if (!SvOK(valuesv))". Improvements to odbc_err_handler documentation. Added 10handler.t test cases. More tests in 02simple.t to check NUM_OF_FIELDS and NAMES_uc. Bit of a tidy up: Removed some unused variable declarations from dbdimp.c. Lots of changes to DBD::ODBC tracing, particularly in dbd_describe, and dbd_error2 and login6. Removed a lot of tracing code in comments or #if 0 as it never gets built. Changed dual tests on SQL_SUCCESS and SQL_SUCCESS_WITH_INFO to use SQL_SUCCEEDED. Martin -- Martin J. Evans Easysoft Limited http://www.easysoft.com http://www.nntp.perl.org/group/perl.dbi.announce/2008/02/msg337.html Tue, 05 Feb 2008 11:09:00 +0000 Announce DBD::Oracle 1.20 (1 message) DBD::Oracle 1.20 Released January 14th, 2008 - by John Scoles The latest release of DBD::Oracle is now ready and can be found at: CPAN DBD::Oracle. It is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles, under the auspices of The Pythian Group as open source/free software. The release has been fully tested with the latest version of DBI (1.601). Below is the list of the changes and/or fixes in this release. Fixed lob test so it skips the one test that relies on it if v$ session. From Rafael Kitover. Fixed // with /* */ in dbdimp.c From John Scoles. Fixed for execute_for_fetch in Oracle.pm returning 0 instead of 0E0. From Martin J. Evans Added README.64bit.txt that contains help for compiling on 64 bit boxes from John Scoles Fixed typo in Oracle.pm from Tom R. Added support for ora_charset, ora_ncharset. From Stephen J. Smith Fixed Makefile.PL for better handling of empty array in File::Find::find. From Slaven Rezic. Fixed references to README.clients.txt in Makefile.PL. From John Scoles. Added PERL_NO_GET_CONTEXT for better multi-threaded support. From John Scoles. Changed required version of DBI to be 1.51. From John Scoles. Fixed bug in 31lob.t. From John Scoles. Added notes on installing Instantclient.rpm to README.Lunix.txt. Added support for OCI array bind. From Alexander V. Alekseev. Added support for select of OCI Embedded Objects. From John Scoles. Added a tip in README.64bit.txt. From cartmanltd. Added fix to Makefile.PL for finding SQLplus for Ubuntu Server (but should work for others). From Martin J. Evans. Added fix to Makefile.PL for Gentoo AMD64. From Tom R. Added fix to dbdimp.c for speed up of Null-Operations. From Andreas Behal. Added fix to dbdimp.c for SQLCS_NCHAR index use on varchar2s. From Peter J. Holzer. The first big addition is Alexander’s patch to add support for array binds with the SYS.DBMS_SQL.VARCHAR2_TABLE and SYS.DBMS_SQL.NUMBER_TABLE types in SQL calls. The next big addition is support for selects of embedded the OCI object types OBJECT, VARRAY and TABLE in any combination and, as far as I know, unlimited depth. Support is seamless and recursive, which means you need only supply a simple SQL statement to get all the values in an embedded object as an array of scalars, or if your embedded object contains other objects or types, an array of arrays of scalars. Please enjoy the new release, and keep an eye open for some blogs on how to use the new additions.

It's just to create more space before bumping up against v2.0. Skipping 1.600 is also not significant, just idle paranoia. =head2 Changes in DBI 1.601 (svn rev 10103), 21st October 2007 Fixed t/05thrclone.t to work with Test::More >= 0.71 thanks to Jerry D. Hedden and Michael G Schwern. Fixed DBI for VMS thanks to Peter (Stig) Edwards. Added client-side caching to DBD::Gofer. Can use any cache with get($k)/set($k,$v) methods, including all the Cache and Cache::Cache distribution modules plus Cache::Memcached, Cache::FastMmap etc. Works for all transports. Overridable per handle. Added DBI::Util::CacheMemory for use with DBD::Gofer caching. It's a very fast and small strict subset of Cache::Memory. =cut The client-side caching for DBD::Gofer is cool and powerful. One handy benefit that might not be obvious is that you can now add client-side caching to any (gofer compatible) application without needing a gofer server or even any code changes. You just define the DBI_AUTOPROXY environment variable like this: DBI_AUTOPROXY='dbi:Gofer:transport=null;cache=1' Couldn't be any simpler. Enjoy!

I've been building some tools for fancier Perl project documentation. One piece is a javadoc-ish formatter using special POD tags. In order to exersize it thoroughly, I've hacked a version of DBI to move the POD around a bit, with some editting to comply with javadoc style guidelines. I don't intend to fold any of the changes into the DBI bundle, but thought the resulting docs might be generally useful (which is also why I chose DBI as an unwitting test subject). For anyone interested, here's a link to the result: http://www.presicient.com/dbidocs Caveats: - Some of the internal links aren't valid - older browsers may not play nice with the javascript or CSS (tho they're pretty basic) - Opera doesn't seem to like 12 digit hex color names, so it renders header sections as a hideous purple instead of the usual nice aqua blue - some of the content may not be correct (tho I tried not to change content other than to use slightly different grammar tense or person) I think the docs are useful, if only because of the explorer-style TOC. I know its handy to me to quickly lookup the meaning of an attribute I've forgotten, or to lookup the right parameters for some method. Any comments/corrections/suggestions welcome, but are probably best sent offlist.

I'm working on a new version, with much better docs, which I hope to release this week. Meanwhile, I've just written a first draft of a user guide that tries to put all the pieces into context: http://dashprofiler.googlecode.com/svn/trunk/lib/DashProfiler/UserGuide.pm Tim. p.s. This is a little off-topic. On the other hand DashProfiler is built on DBI::Profile, so that's my excuse.

From the changes file: Fix bug reported where ping crashes after disconnect thanks to Steffen Goeldner. Fix bug in dbd_bind_ph which leads to the error Can't change param 1 maxlen (51->50) after first bind in the 20SqlServer test. This is caused by svGROW in Perl 5.8.8 being changed to possibly grow by more than you asked (e.g. up to the next longword boundary). Fix problem with binding undef as an output parameter. Reported by Stephen More with IBM's ODBC driver for iSeries. Removed comment delimiters in comments in dbdimp.h leading to warnings. Removed some unused variable declarations leading to warnings. Removed PerlIO_flush calls as it is believed they are not required. Add logging for whether SQLDescribeParam is supported. Fixed use of unitialised variable in dbd_bind_ph where an undef is bound and tracing is enabled. Fixed issue with TRACESTATUS change in 20SqlServer.t tests 28, 31, 32 and 33 leading to those tests failing when testing with SQL Server 2005 or Express. Many compiler warnings fixed - especially for incompatible types. Add provisional Unicode support - thanks to Alexander Foken. This change is very experimental (especially on UNIX). Please see ODBC.pm documentation. Also see README.unicode and README.af. New database attribute odbc_has_unicode to test if DBD::ODBC was built with UNICODE support. New tests for Unicode. New requirement for Perl 5.8.1 if Unicode support required. New -[no]u argument to Makefile.PL. New warning in Makefile.PL if Unicode support built for UNIX. Fix use of unitialised var in Makefile.PL. Fix use of scalar with no effect on Makefile.PL Added warning to Makefile.PL about building/running with LANG using UTF8. Added warning to Makefile.PL about using thread-safe ODBC drivers. Updated MANIFEST to include more test code from mytest and remove MANIFEST.SKIP etc. Removed calls to get ODBC errors when SQLMoreResults returns SQL_NO_DATA. These are a waste of time since SQL_NO_DATA is expected and there is no error diagnostic to retrieve. Changes to test 17 of 02simple.t which got "not ok 17 - Col count matches correct col count" errors with some Postgres ODBC drivers. Caused by test expecting column names to come back uppercase. Fixes by uppercasing returned column names. Changes to tests in 03batt.t which correctly expects an ODBC 3 driver to return the column names in SQLTables result-set as per ODBC 3.0 spec. Postgres which reports itself as an ODBC 3.0 driver seems to return the ODBC 2 defined column names. Changed tests to catch ODBC 2.0 names are pass test put issue warning. For postgres skip test (with warning) checking $sth->{NAME} returns empty listafter execute on update Updated FAQ, added a few more questions etc. DBD::ODBC requires at least 5.6.0 of Perl. Many updates to pod documentation.

You can see it now, with nicely HTMLized documentation, at: http://search.cpan.org/dist/Muldis-DB/ This is the first formal release of Muldis::DB, which began development last year (under the temporary name of "QDRDBMS") as a rewrite of my previously released but never functional "Rosetta" project. Muldis::DB is implemented as a library or open-ended framework for use by larger frameworks or applications, and is a DBMS resource to them. This project comes in twin Perl 5 and Perl 6 versions which are feature identical; the former is for use in today's systems, and the latter is for longer term use; if there is a case for doing so, some parts may be moved to other languages later such as C. The equivalent Perl 6 version of Muldis::DB to the CPAN release is bundled with the "Pugs" ( http://www.pugscode.org/ ) implementation of Perl 6, and its release to CPAN follows Pugs' schedule. Meanwhile, you can see it in the ext/Muldis-DB/ sub-directory of Pugs' version control. With both initial versions, Muldis::DB has zero external dependencies but for Perl/Pugs itself and what is bundled with it; this should ease installation. If you want to read all the Muldis::DB documentation that exists now, I recommend doing so in this order: 1. http://search.cpan.org/src/DUNCAND/Muldis-DB-0.0.0/README 2.

(opt) http://search.cpan.org/src/DUNCAND/Muldis-DB-0.0.0/TODO 11. (opt) anything else The "README" file above includes the urls of the public version control systems that host the development of Muldis::DB. The Perl 5 version is hosted in a public GIT repository hosted by Sam "Mugwump" Vilain, for which I am thankful. The Perl 6 version is hosted in the same public Subversion repository as Pugs. Muldis::DB defines and implements a computationally complete programming language with integrated relational database functionality. It is an open-ended framework with a separate programmatic API and pluggable implementing engines, one of which is bundled with the core so it works out of the box. The framework is intentionally similar to the DBI framework in organization. Muldis::DB implements a D language (named "Muldis D") as defined by Hugh Darwen and Chris Date, and presents a superior interface for working with the relational model of data, contrasted with SQL. Anyone familiar with SQL or the relational model, or just programming in general, should find it easy to learn. One general strength of Muldis D (truly relational) over SQL (quasi-relational) is that there is next to no object-relational impedence mismatch since the true relational model can natively represent user-defined complex data type structures, constraints, and operators; there is no need for "object-relational mappers", except for their role in tighter host language integration. Another general strength of Muldis D is that any arbitrary business rules can be cleanly expressed as constraints on a database, so it is easier to trust a database to ensure its data state or transitions are always conformant to business rules, without hoisting such integrity matters to the application, where it is a lot more difficult to do it reliably. Since a D language can represent anything, a SQL database and/or SQL features can also be emulated over one, which helps with legacy migration; similarly, as much as is possible, existing SQL engines can be used to implement Muldis DB over top of, in which case Muldis DB acts as a SQL generator to access pre-existing databases in new applications. Conceptually speaking, Muldis::DB is either a replacement for DBI, or a replacement for any SQL DBMS itself, depending on how you use it; out of the box it replaces both, but plug-in bridges can be made that bridge to either. Taking the Perl 6 development process as a model, Muldis D has an authoritative human-readable design document (the Language.pod file), which is analagous to the Perl 6 Synopsis documents, and one or more separate conforming implementations (the other files). It is very feasible that Muldis D could have multiple implementations, over any languages, besides the 2 (Perl 5 and Perl 6) that exist now. More information is in the Muldis::DB documentation. I would probably like to say that Muldis::DB would be a panacea to all your database ills, but instead I see it more like Muldis::DB should provide a more solid skeleton on which to build the solutions to all your database ills than are any other solutions. I will contribute to the solutions as best I can. Several public email-based forums for Muldis::DB now exist (with public archives), all of which you can reach via http://mm.DarrenDuncan.net/mailman/listinfo (note that Mailman's monthly password reminder email is turned off). There are currently 3, for 'announce', 'devel', 'users', modelled after the main lists for DBI. I invite you to join one or more of these lists (if you haven't already), to better facilitate discussion, support, and group development. As of this version-zero release, Muldis-DB is officially in pre-alpha development status. A lot of documentation and functionality is present, but a lot isn't. What is mostly done is the higher level documentation plus an alpha-quality but fundamentally stable public API implementation. What is mostly undone is the reference engine implementation, the test suite, and documentation of the API details. What is already present should be sufficient to begin study of Muldis-DB such that it can actually be put to use within the next few weeks or months as Muldis-DB is fleshed out. Also, it should be possible now to start writing code that uses or extends it. To conclude, I would be very greatful for any and all kinds of assistence with the Muldis::DB framework that you can provide, which includes building or sponsoring features and extensions. Probably the very first kind of help that I could use the most is with writing cookbook-type examples of using Muldis::DB and/or FAQ documents. This both helps people learn how to use it in an effective manner, and also helps flesh out deficiencies in Muldis::DB. Both the "how do I define this kind of database" variety and "how do I express this SQL in Muldis D" variety are helpful. These examples would be released as a Muldis::DB::Cookbook distribution. I also welcome general feedback, constructive criticism, suggestions, corrections, and questions. Note that I prefer any responses to happen on-list, or that you sign up to and post to a muldis-db list (only list subscribers may post), so that that and any replies can be for the group's benefit, and to save me from repeating the same answers ad nauseum. Unless the response is not suitable for public discourse, in which case, sure, go private email; ditto if you're not sure about appropriateness.

It's relatively rare for perl to be configured that way, even on 64-bit systems. Fixed XS versions of select*_*() methods to call execute() fetch() etc., with inner handle instead of outer. Fixed execute_for_fetch() to not cache errstr values thanks to Bart Degryse. Fixed unused var compiler warning thanks to JDHEDDEN. Fixed t/86gofer_fail tests to be less likely to fail falsely. Changed DBI::hash to return 'I32' type instead of 'int' so results are portable/consistent regardless of size of the int type. Corrected timeout example in docs thanks to Egmont Koblinger. Changed t/01basic.t to warn instead of failing when it detects a problem with Math::BigInt (some recent versions had problems). Added support for !Time and !Time~N to DBI::Profile Path. See docs. Added extra trace info to connect_cached thanks to Walery Studennikov. Added non-random (deterministic) mode to DBI_GOFER_RANDOM mechanism. Added DBIXS_REVISION macro that drivers can use. Added more docs for private_attribute_info() method. DBI::Profile changes: dbi_profile() now returns ref to relevant leaf node. Don't profile DESTROY during global destruction. Added as_node_path_list() and as_text() methods. DBI::ProfileDumper changes: Don't write file if there's no profile data. Uses full natural precision when saving data (was using %.6f) Optimized flush_to_disk(). Locks the data file while writing. Enabled filename to be a code ref for dynamic names. DBI::ProfileDumper::Apache changes: Added Quiet=>1 to avoid write to STDERR in flush_to_disk(). Added Dir=>... to specify a writable destination directory. Enabled DBI_PROFILE_APACHE_LOG_DIR for mod_perl 1 as well as 2. Added parent pid to default data file name. DBI::ProfileData changes: Added DeleteFiles option to rename & delete files once read. Locks the data files while reading. Added ability to sort by Path elements. dbiprof changes: Added --dumpnodes and --delete options. Added/updated docs for both DBI::ProfileDumper && ::Apache. =cut You can see the primary focus of my recent developments for Shopzilla have been around profiling. Specifically using the DBI's profiling mechanisms to implement lightweight always-on application-level profiling. Enjoy! Tim. p.s. I've a new module, called DashProfiler, that provides a simple, flexible, efficient way to add performance monitoring to an application, especially web applications. It's trivial to track the time spent inside specific blocks of code, or the lifespan of specific objects. (It happens to use DBI handles internally to store profile data but is unrelated to databases. A working version, but with almost no docs, is on CPAN. I'll announce the documented version when I release it but I won't be using the dbi mailing lists for DashProfiler in future.) http://www.nntp.perl.org/group/perl.dbi.announce/2007/06/msg322.html Tue, 19 Jun 2007 15:12:18 +0000 DBD::mysql 4.005 Released (1 message) Dear DBD::mysql users and developers, I'm pleased to announce the release of DBD::mysql 4.005! This release contains various fixes, per Changelog: * Fixed mysql_warning issue < 4.1 (reminders, patches, help from ROAM, (issue 25713) * makerealclean patch from ROAM (issue #25714) * sqlstate cleanup patch from ROAM * Replaced all references to dbis->debug to use DBIc_TRACE_LEVEL(imp_xxh) * Fix to dbd_st_destroy - added back previously removed 'free everything' code which had been moved to dbd_st_finish, causing a crash upon freeing of bind values after all rows resulting from one execution of a query have been fetched. This meant that next attempt to execute the prepared statement would segfault. This work thanks to Rainer Weikusat! * Removed all 'FindNewTable' calls in all tests. Just use 't1' for all tests to simplify things. * Better 'skip test'
