> To make T2 driver supports rowset operation to enhance the performance of 
> batch insert and update, two SQL transactions ("commit" to make a succeeded 
> execution and "rollback" for failure) are required to be prepared in advance, 
> which shall be triggered in executing phase of rowset operation.
