RE: select from oracle and write to file

To avoid this error declare variables as 

my @row;
my $oid;

before using it, this would solve all your problems.

Thanks for the help!! I think it's almost there. This is what my script look

like now:

use strict;
use DBI;

open(TEXTFILE,">output.txt");

my $dbh = DBI->connect( 'dbi:Oracle:db',
                        'user',
                        'passwd',
                        {
                        RaiseError => 1,
                        AutoCommit => 0
                        }
                        ) || die "Database connection not made: 
$DBI::errstr";
my $sql = qq{ SELECT oid FROM bv_ep_project };
my $sth = $dbh->prepare ( $sql );
$sth->execute();

        while( @row = $sth->fetchrow_array )
                {
                        $oid=$row[0];
                        print TEXTFILE"$oid\n";
                }
$sth->finish();
$dbh->disconnect();

And these are the errors I get:

Global symbol "@row" requires explicit package name at ./one.pl line 23.
Global symbol "$oid" requires explicit package name at ./one.pl line 25.
Global symbol "@row" requires explicit package name at ./one.pl line 25.
Global symbol "$oid" requires explicit package name at ./one.pl line 26.

Any input as to why this happens??
