[mapserver-users] WFS on a view from a spatialite source

[Andrea Peri]

Hi Jukka.

effectively the work of spatialite with mapserver is quite strange. :)

But thx to youe response I have resolved and it work. :)

Infact my original setting was exactly:

DATA 'select field1,field1,field3 from my_view'

I usually use this configuration because it is better for the
GetFeatureInfo wms's requests.

And with this configuration the wfs seem don't work.

But if I change to this other configuration:

DATA 'my_view'

It work.

As you can see
http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map=wmstest&service=wfs&version=1.1.0&srsname=epsg:25832&request=GetFeature&typename=v_lista_comuni_ordered_prov_com&propertyName=nprov,ncom,codcom,codprov&sortBy=ncom

But the response is quite strange because the response is not sorted on the
"ncom" attribute,
and also
I see two attribute are lowercase and two are uppercase.

This is strange because the view is defined with the alias always lowercase.

However it now work and this is a good start point.

Thx,
