Hi Everyone,

I want to do a subselect from my .map file. I went through some =
list-archive from that I tried these statements.

DATA "the_geom from westminster"  works fine
DATA "the_geom from westminster using unique oid using srid=3D-1"    =
works fine
DATA "the_geom from (select oid,the_geom from westminster) as foo using =
unique oid using srid=3D-1"  no result

I've got two tables, one with geom, other with features... I want to =
display the certain feature as label on the map.

What I'm missing in the above sql? Am I doing anything wrong? Is there =
anything on database level that I have to change?

Will Appreciate any inputs
Regards
Nida.
