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
