In fairness to anyone else that might read this and copy it, it is not
actually correct if you are using
unixODBC which does not have an "ODBC Data Sources" section at all. Now
I am wondering
if you were really using unixODBC or in fact iODBC or some other driver
manager.
Your principle problem was neglecting to specify dbi:ODBC in the DBI
connection string (which
you concede below) and it was compounded by using driver= instead of
DRIVER= in the ODBC
part of the connection string. Had you corrected these, I'm sure you
would have connected ok
as freeTDS knows about unixODBC and happily works with it.

In actual fact if you read the FAQs mentioned in a previous posting on
this thread you will
see that although the above works, 'dbi:ODBC:DSN=TEST' is better - see
http://www.easysoft.com/support/kb/kb00097.html for why.

Interestingly, an age old issue arises out of your post which is what
the ODBC specification says
you should report as an error for certain situations e.g. DSN not found
and no DEFAULT found....
In reality, on UNIX no one writes a default section in their odbc.ini
file so the misdirection to a
DEFAULT driver nearly always confuses. The reality is when you specified
driver={xxx} the
driver manager could not find a DSN= or a DRIVER= so it errored with the
less than helpful error
that ODBC says it should. I will pass this on to Nick (@unixODBC) to see
if he can be persuaded
to deviate from the the spec and provide a slightly more useful message
(as Tim has done to a different
degree in DBI).
