void __fastcall CloseDataSets();
Closes all datasets associated with the SQL connection object component without disconnecting from the database.
Call CloseDataSets to close all active datasets without disconnecting from the database server. Ordinarily, when an application calls Close, all datasets are closed, and the connection to the database server is dropped. Calling CloseDataSets instead of Close ensures that an application can close all active datasets without having to reconnect to the database server at a later time.
