INSERT, UPDATE, DELETE statements are generated by ClientDataSet but not our driver. So we ask you to test your application using standard driver. If problem disappears using standard driver please send (dbxmda*crlab*com) a complete small sample to demonstrate it, including script to create and fill table.
