[Mapserver-users] Query OGR Datasource?

[Zak James]

Joost,

Assuming the ogr connection is set up correctly, you should have query 
access to any attributes that are present in the table alongside the 
x,y geometry. It should behave like a shapefile dbf in that respect. 
Make sure you have TEMPLATE defined for the layer. Are you setting this 
up via mapscript or cgi mode?

If you don't get what you expect, use ogrinfo -ro file.ovf from a shell 
to determine what's available.
