Hello Frediano,

First of all, thank you for your answer and help.

Unfortunately this server is on my employee's internal network and not
exposed on the open internet.

I'd gladly run any code you provide against the server if you want,
and report back the results to you.

I have already downloaded latest freetds CVS source code and tried to
compile it, with success, but I'm still trying to figure out how to
convince unixodbc to use my compiled version. I though that only
changing odbcinst.ini would be enough, however it seems to point to
some libtdsS.so which haven't been built by default. I guess that's a
separate issue and if I can't figure it out I'll start another thread.

I have some news that can help the issue:

The code I originally posted prints the version as reported by odbc.
As I said, the problematic SQL Server is reporting '08.00.0760' as the
version.

I have two other copies of SQL Server 2000 around so I tried the code
against them. They report versions 08.00.2039 and 08.00.2187 and both
run the code fine. So you're right about the exact patched version
'08.00.0760' as being related to the problem.

If there's anything else I can do to help find the problem, please tell me...

Again, thanks in advance.
