SYMPTOMS

If an ODBC application does a SQLNumResultCols() after a SQLPrepare() of a query containing a GROUP BY in a subquery, but before having issued SQLExecute(), the Microsoft SQL Server ODBC Driver will issue an error:

szSqlState = "37000", *pfNativeError = 107, *pcbErrorMsg = 134
szErrorMsg="[Microsoft][ODBC SQL Server Driver][SQL Server]
The column prefix 'B' does not match with a table
name or alias name used in the query."

WORKAROUND

Do not issue the SQLNumResultCols() call until after issuing the call to SQLExecute().

STATUS

Microsoft has confirmed this to be a problem in the Microsoft SQL Server ODBC Driver version 2.50.0121. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
