Left = 280
Top = 16
end
object DataSource1: TDataSource
DataSet = ClientDataSet1

end

thanks for your help.

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.
