[postgis-users] Querying MapServer PostGIS layer

[Dave Stone]

Further to my earlier post, on a suggestion by Pericles Nacionales, I 
tried simplifying the DATA statement in the .MAP file by removing the 
USING clauses. Thus

DATA  "geom from loccoords using srid=27700"

or even

DATA  "geom from loccoords"

work OK, but

DATA  "geom from loccoords using unique locationref using srid=27700"

doesn't, despite there being a B-tree index on locationref. 
Investigation continues.

Cheers,

Dave
