[Qgis-user] WFS rendering issues

[Paul Wittle]

Hi,

I wanted to load a WFS layer into QGIS and I've found that when using QGIS at work it will not work if the layer source is MSSQL or Oracle but is fine if the database source is PostGIS. Has anyone else had any experience of getting it to work for MSSQL?

I'm using GeoServer to serve up the WFS feed so to replicate you need to create a table with at least one multipolygon in MSSQL and connect it up as a layer in GeoServer; you then try to load it into the QGIS.

When I do this I find that QGIS loads it without error and the network logger shows everything working but nothing draws on the map and when I open the attribute table the correct number of records is show in the total but zero are actually in the table even when selecting all records.

If you have a working example I'd be grateful if you can point me in the right direction as perhaps I'm missing a step when setting up a table in MSSQL or perhaps creating the layer in GeoServer. I'm aware that this request may sound like a MSSQL or GeoServer issue but I think it is more about understanding what QGIS is expecting. It may be that I need to change something in the other applications but the key here is that as far as I can tell I'm getting valid WFS from GeoServer in all cases but QGIS is only drawing it if it comes from PostGIS.

This is using QGIS 3.16.x long term release.

Any hints would be gratefully received.
Thanks,
Paul
