[mapserver-users] newbie: Error in first atttempt to use postgis with mapserver?

[Saka Royban]

Thanks alot
you are right. although i could understand from error message to have a OID column (it is gid in my table), my mistake was about ignoring 'USING' in 'USING UNIQUE gid).
thanks again to help me

Newer versions of Postgres do not automatically create an OID column, as it was a limited 32-bit construct.

Try add "using unique XXX" where XXX is the column name of the primary key (or at least a unique key).  If you've uploaded the layer from a shapefile using ogr2ogr you can use the column "ogc_fid"

Hi everyone.
i've used workshop material of FOSS4G2007 (PostGIS workshop)to learn postgis
along with its data. but there is a problem
i got this error in first attempt to retrieve data from postgis:

msDrawMap(): Image handling error. Failed to draw layer named
'bc_municipality'. prepare_database(): Query error. Error declaring cursor:
ERROR: column "oid" does not exist LINE 1:
...inary(force_collection(force_2d(the_geom)),'NDR'),OID::text ... ^ With query string: DECLARE mycursor BINARY CURSOR FOR SELECT
asbinary(force_collection(force_2d(the_geom)),'NDR'),OID::text from
bc_municipality WHERE the_geom && setSRID('BOX3D(458426.1 260651.497368421,1943216.4 1373313.90263158)'::BOX3D,
find_srid('','bc_municipality ','the_geom') ) msPOSTGISLayerRetrievePGVersion():
Query error. Error executing POSTGIS statement
(msPOSTGISLayerRetrievePGVersion():select substring(version() from 12 for
(position('on' in version()) - 13)) 

i don't know what causes the problem although it sounds easy.
THX
