chjhaijiang Yes, MSOLEDBSQL supports multiple statements in a single command. However, you need to process all result sets, check return codes, and process error information in order to ensure you receive all errors that might be generated by subsequent result sets. In your case, the first statement (USE myDB;) generates the first result set and does not generate any errors. See the documented comments on the IMultipleResults::GetResult OLE DB interface for good descriptions of when errors might occur. The Using IMultipleResults to Process Multiple Result Sets is another good place to start to read about how to consume multiple result sets.
