I see Borislav and Vladimir aleady answered. Your sample code was not using DSNless connections with SQLSTRINGCONNECT() as I advised.
Another (unrelated) issue I see in one of the later examples on this thread is the use of user 'sa' which is the Admin. This is a bad idea. System Admin account should only be used for system administration tasks, not for everyday queries and other database daily operations. That is a security risk. Make your programs aleways use a normal user (restricted account) instead of 'sa'.
