Hi , I sent out an email asking about the following error messages, I don't know if it got posted - Cannot handle multiple result groups & Unknown Response Type I am wondering if the following two situations are permitted/handled in the JDBC driver - 1. Multiple threads making different/separate queries(Statements) using the same connection, at the same time 2. Multiple threads making the same type of query(same Statement) perhaps with different parameters, using separate Connections. 3. I would like to reuse a PreparedStatement, is closing the ResultSet after each query enough. Thanks, Rini __________________________________________________ Do You Yahoo!?
