Information can be extracted from the result set with a LIMIT 0 select, and I believe this is what qgis already does. You can see which tables are being addressed and whether those tables have a primary key, but it ain't easy to determine if those primary keys will appear uniquely in the output. --strk; _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
