[postgis-users] layer postgis query box

[Sébastien DUBOIS]

I'd imported in the Gmap soft (from dmsolutions phpmapscript+mapserver+rosa)
a postgis layer build with shp2pgsql 

>createdb montelimarpostgis
>createlang plpgsql montelimarpostgis
>psql montelimarpostgis < /home/postgre/postgis.sql
>psql montelimarpostgis < /home/postgre/spatial_ref_sys.sql 
>shp2pgsql -D /var/www/html/workshop/data/Clients.shp clientspostgis
montelimarpostgis | psql montelimarpostgis

then

montelimarpostgis=# \d clientspostgis
                                  Table "public.clientspostgis"
   Column   |       Type        |                            Modifiers

my layer in my .map looks like this :

---------------------------

With this code, i succeed in displaying my point (with label POINT(X,Y))

BUT

*when i make a query on ONLY ONE POINT I can't display the attributes of my
original shapefile (so the colums of clientspostgis)
My metadata is correct ...
No error when i query only no display

*when i make a query on MULTI points: ERROR
-------------------------------
Warning: [MapServer Error]: msPOSTGISLayerGetShape(): Error executing POSTGIS
SQL statement (in FETCH ALL): DECLARE mycursor BINARY CURSOR FOR SELECT
the_geom::text,asbinary(force_collection(force_2d(the_geom)),'NDR') from
clientspostgis WHERE oid = 19621 -ERROR: cursor "mycursor" already exists
More Help:
Error with POSTGIS data variable. You specified ''.
Standard ways of specifiying are :
(1) 'geometry_column from geometry_table'
(2) 'geometry_column from (<sub query>) as foo using unique <column name> using
SRID=<srid#>'

Make sure you put in the 'using unique <column name>' and 'using SRID=#' clauses
in. 
----------------------




I've read that sometimes in old version the multipoint query error is due to
postgis not closed at the end of a requet but i have the last version of
mapserv and postgis ...

CAN SOMEONE GIVE ME SOME HELP??
