After instrospection,
when adding to QGIS an 'OGR VRT' layer with SrcSql tag, iterarator with spatial filter return no features. This seems to be due to OGR. Does anybody know a workaround about this ? Arnaud
I am working with OGR VRT files in QGIS. When I use the "SrcLayer" tag, all works correctly. But when I use "SrcSQL" tag, QGIS seems to load the file correctly, but nothing appears in the canvas. exemple: <OGRVRTDataSource> <OGRVRTLayer name="test_shp_sql"> <SrcDataSource relativeToVRT="1">test.shp</SrcDataSource> <SrcSQL dialect="sqlite">SELECT * FROM test</SrcSQL> </OGRVRTLayer> </OGRVRTDataSource> all attributes are correctly displayed in the attribute table. when I use Save As ... to another shapefile, the new file display correctly. "ogrinfo -la" gives me exactly the same results for "SrcLayer" and "SrcSQL" tags. I've also tried the getWKT plugin which give me the same result for features from the two layers. I do not understand what goes wrong : OGR or QGIS ?
