Jelmer,
Also, when using WFS from Oracle, you should add the wfs_extent or
ows_extent metadata tags. Otherwise MapServer will request Oracle to do a
convex_hull to get the extent of your data. On large datasets, this can take
a while. Setting the extent metadata tag bypasses this check and uses the
value you specify.

Jukka,
Thanks for the little tip! I just tested the test url you gave me, and it
also didn't return anything. After checking the log files I found this:
[Wed Nov 18 13:50:46 2009].176000 msOracleSpatialLayerGetShape():
OracleSpatial error. Error parsing OracleSpatial DATA variable for query. To
execute query functions you need to define one unique column [USING UNIQUE
#column]
Chaning the query from
DATA GEOLOC FROM ADDRESS USING SRID 90112 VERSION 10g
to
DATA GEOLOC FROM ADDRESS USING UNIQUE ID SRID 90112 VERSION 10g
Did the trick. Not too bright of me that I didn't check the log file, I admit,
but might I recommend outputting this message to the client anyway?
Thanks for the help, I can now continue fiddling with projections, my
favorite! *sigh* :)
Regards,
Jelmer

Hi,
If you haven't done it yet, check that you can for sure get
some data out of your service.
mapserv.exe?map=address.maptypename=addressSERVICE=WFSVERSI
ON=1.0.0REQUEST=GetFeatureMaxFeatures=10
If yes, have a look at the returned data and see what kind of
coordinates it likes to send you. Just to be sure that your
BBOX is correct. Also, add DEBUG=5 to the layer definitions
and look at the Mapserver errorfile to understand more about
what is happening.

Aihe: RE: [mapserver-users] MapServer, WFS and Oracle
Bart, Jukka,
The shoes taste wonderful. The request comes from OpenLayers,
and I can't find how to change it to WFS 1.1, but that'll be
another Google search, soon. Right now I thought it'd be
smart to see if I at least can get *some* results, manually.
This however also fails.
My current request
mapserv.exe?map=address.maptypename=addressSERVICE=WFSVERSI
ON=1.0.0REQUEST=GetFeatureSRS=EPSG%3A28992BBOX=125474.0
0,381967.999850,206652.000100,470382.335300
The coordinates come from a previous request (gml:boundedBy)
and should definatly contain some points. An select count(id)
from address where x 125474 and y 206652 and x 381967
and y 470382 returns 24002 rows (the geo object is also
saved as plain X/Y).
For completeness, here's my current MAP file:

As you can see, I use the Dutch projection system everywhere.
Yet the request only returns:

Hi,
I hope you have tasty shoes. WFS 1.0.0 does officially
support only
one
