Hello all,


Far from being expert in ODBC, I managed to use unixODBC in conjunction
with FreeTDS on RedHat 7.3.  tsql works great, isql works great and I
can tap into my data sources.


Now the purpose of all this is to get Lotus Domino running on that box
to tap into MS SQL server data sources.  

Up to freetds-0.61, Domino was crashing when trying to access the
datasource for some reason. In 0.61 the Domino ODBC test could not
report on freetds-odbc drivers details (returning "Operation not
supported"), now the latest nightly build does work and reports all
required Domino driver details.  Now Domino does not crash anymore!!!
Thanks for making that work!  Am I right to say that freetds-unixodbc
wasn;t completely unixODBC compliant???


In Lotus Notes Designer, you can set up ODBC data sources and get it to
point to a unixODBC datasource on the system the Domino Server runs on.
Once you have done that you can click on a button to browser metatadata
(Tables of a database)  It works great with unixODBC / MyODBC (MySQL
ODBC driver) - I can see and pick tables from a database.  But when I
use a FreeTDS unixODBC datasource it does not work (Domino says can't
find any Metadata)

After a bit of investigation and analysing the loigs I notices that the
following strored procedure was called by my "Browse Metedata" button
click:

sp_tables @table_type='TABLE'

Ran this from isql and no row came back

I went in the SQL query analyser on the MS SQL server I'm trying to
reach throuch unixODBX and ran it: no row came back.

Looked at the MS Sql books online to fine out that the correct syntax
shoould be:

sp_tables @table_type="'TABLE'"

Rand that from isql and all tables come back.


So my question is:


Is there a way to make freetds-unixodbc run that sp_table query by
enclosing the @table_type value in double quotes. Or is it domino that
should know it talks to a MSSQL server and should add these
double-quotes before calling unixODBC API?  Or is it unixODBC API which
should add those double quotes???


Any thoughts anyone?

Thanks for your help!

Patrick
