Here is a sqlite topic on that [0] And here my initial post in qgis list [1] [0] http://sqlite.1065341.n5.nabble.com/Computed-columns-in-VIEWs-return-NULL-but-should-be-able-to-be-typed-Any-ideas-td56769.html#a56770 [1] http://osgeo-org.1560.x6.nabble.com/Spatialite-can-t-type-fields-of-a-view-td5058436.html -- View this message in context: http://osgeo-org.1560.x6.nabble.com/have-aggregate-window-expressions-ever-been-discussed-tp5142215p5142714.html Sent from the Quantum GIS - Developer mailing list archive at Nabble.com. _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
