Why am I writing about this? Because curiosity is in the blood.🙂 My next step was to mix TMySQLDataset descendant from MySQLDAC as master and PostgresDAC’s object as slave. Holy molly! It works. Then I tried another TDataset descendants from BDE, ADO, FIBPlus etc.
They can be mixed any way you want. Yeah, baby! True perversion.🙂
