SYMPTOMS
Calling SQLNumResultCols after SQLPrepare of a SELECT statement that contains a subquery in the select list will fail with:

szSqlState = "37000", pfNativeError = 156

szErrorMsg="[Microsoft][ODBC SQL Server Driver][SQL Server]

Incorrect syntax near the keyword 'SET'."



CAUSE
When the SQL Server ODBC driver constructs the T-SQL statement that will be sent to the server to resolve the number of columns that will be returned in the resultset, it incorrectly parses the initial query and excludes the final table name. For example: SQLPrepare(hstmt, "SELECT t1.c1, (SELECT t2.c1 FROM t2)                     FROM t1", 44) SQLNumResultCols(hstmt, pcol1) This results in the following statement being sent to the server on the call to SQLNumResultCols: SET FMTONLY ON SELECT t1.c1, (SELECT t2.c1 FROM t2) FROM SET FMTONLY OFF Hence, causing SQL Server to report "Incorrect syntax near the Keyword 'SET'."



WORKAROUND
Where possible convert the offending query to a SQL Server VIEW.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server ODBC Driver version 2.65.0201. This problem was corrected in U.S. Service Pack 1 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.
