This is most likely because OGR cannot determine a primary key on your
table. It needs a primary key to operate queries (not for a map display).
A few questions:
1) which version of GDAL?
2) which version of Mapserver?
3) you can try to use CONFIG "OGR_FID" "name_of_your_primary_key" at your
MAP object if automatic detection of the primary key fails
Best regards,
Bart

Onderwerp: [UMN_MAPSERVER-USERS] getFeature: Results are not correct
Hello,
first of all sorry for cross posting, but I've got no idea where I have to
search the mistake so I post it to the GDAL and the Mapserver Mailinglist.
I'm trying to publish a WFS-Server. The Data (only Point-Data) are in a
PostgreSQL-Database (no PostGIS!). So the connection to the data is over
"Virtual Spatial Data". The getCapabilities and DescribeFeatureType request
both work very well. Only the GML-Document getting with the getFeature
request is not correct. The number of features in the GML-Document are
correct too every time, but the features are not in the Bounding Box. The
features in the GML-Document are always the feature which are on the top of
the table they come from. Only the number of feature is correct. The MBR
(Minimum Boundig Rectangle) on the top of the GML-Document amasingly the
correct one. So it don't fit to the features in the document. Testing the
connection with "ogrinfo" and a Boundig-Box is working correct. If I'm
trying to make a WMS-Server with the same Data and the same OGR-file it
works very well.
So here is my Mapfile:
MAP
NAME WFS_Server
STATUS ON
WEB
METADATA
"wfs_title" "WFS Server"
"wfs_onlineresource"
"http://127.0.0.1/cgi-bin/mapserv.exe?"
"wfs_srs" "EPSG:4326"
END
END
PROJECTION
"init=EPSG:4326"
END
LAYER
NAME myWFS
METADATA
"wfs_title" "myWFS"
"gml_include_items" "all"
END
TYPE POINT
STATUS ON
CONNECTIONTYPE OGR
CONNECTION "test.ovf"
PROJECTION
"init=EPSG:4326"
END
DUMP TRUE
END
END
and the OGR-File test.ovf:
<OGRVRTDataSource>
<OGRVRTLayer name="feature">
<SrcDataSource>PG:host=192.168.5.86 user=cwilmes dbname=rosoapcw
password=xxx</SrcDataSource>
<SrcLayer>feature</SrcLayer>
<GeometryType>wkbPoint</GeometryType>
<LayerSRS>EPSG:4326</LayerSRS>
<GeometryField encoding="PointFromColumns" x="lat" y="lon"/>
</OGRVRTLayer>
</OGRVRTDataSource>
Here is a URL which I used for testing
the
WFS
getFeature-Request:
http://localhost/cgi-bin/mapserv.exe?&REQUEST=GetFeature&VERSION=1.0.0&SERVI
CE=WFS&TYPENAME=myWFS&&BBox=9.98,7.98,10,8
....and here is the result:

I will be very thankful for every idea where the mistake could!
Please excuse my bad english!
