Hi,

I've recently been testing the EiffelStore binding to ODBC against a MSSQL 
database. For
that I'm using unixODBC and freetds. However our code does not work due to 
the fact that
when calling SQLDescribeCol with almost no arguments to get the length of the 
column name
it does not return anything.

The code we have looks like:

  rc = SQLDescribeCol(hstmt, (SQLSMALLINT) index, NULL, 0, &indColName, NULL, 
NULL, NULL,
NULL);

I looked at the code of SQLDescribeCol and found that in very old versions it 
would update
indColName and in the latest version although there is a comment at line 2009 
of odbc.c
that says:

        /* cbColNameMax can be 0 (to retrieve name length) */

but nothing to that effect. Actually if you look at the following diff:

https://gitorious.org/freetds/freetds/commit/5508af66b79f1c6dee70d86f9c673e8b9b1b24ed

you see that the code that used to update pcbColName has disappeared from the 
current
version.

Am I missing something?

Thanks,
Manu
