[mapserver-users] Using unique

Hi again,

I'm answering to my by myself :-)

When I add to the end of my query "using unique" as:
" as foobar using unique oid "
then query is again running ok. 
I also tried it with older version of Mapserver (5.4.2). Both versions are working ok with it.

After some debugging of version 5.6.6, it seems to me , that in query, there is missing last right parenthesis if "using unique" is omitted. Some bug?

. The 
using unique
 and 
using srid=
 clauses are optional, but using them improves performance.
