All database-like formats, even Shapefile's DBF, support sorting on database level. I've never understood, why some applications download the whole content first and Microsoft Access is such a "problem". Some days ago, it has downloaded 700 MB of data from the database to figure out "first" and "min/max". Access has a "pass-through" function for this to make it directly work on database level, but it's somehow hard to handle. But you're right. For things like sorting in calculation, there has to be a different solution, like threaded or staged or using "processing" toolbar only. My system can't even handle to download 3 * 10^6 attributes :( _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
