Does anyone have a clue regarding what I have to do, to sort out
this issue?
there is a clue in the log file :
[Mon May 25 14:03:08 2009].187807 msPostGISLayerWhichShapes(): Query
error. Error (ERROR: argument of WHERE must be type boolean, not type
geometry
but if you look at your query in the log file (trying to make it look
a bit nice for legibility) :
FROM (
SELECT geometri, *
FROM general.country
WHERE ST_Intersection(geometri,GeomFromText('POLYGON((12 0,18 0,18
84,12 84,120))',4326))
) AS country
You have a WHERE clause that returns a geometry (here is the manual
entry)
ST_Intersection(geometry, geometry) Returns a geometry that
represents the point set intersection of the Geometries.
In other words - that portion of geometry A and geometry B that is
shared between the two geometries.
So you need to actually compare something with the geometry to make
the where clause work.
I hope this helps to steer you in the right direction... I have no
idea what you are trying to compare!

Hi, thanks for the help!
I tried your suggestion, but I didn't manage to get it to work
correctly,
this is what I did:
Entered the following DATA statement:
DATA "geometri from ( select geometri, * from general.country where
ST_Intersection(geometri,GeomFromText('POLYGON((12 0,18 0,18 84,12
84,12
0))',4326)) ) AS country USING UNIQUE ogc_fid USING SRID=4326"
but I then got the following error in the MapServer logfile:
[Mon May 25 14:03:08 2009].185400 msPostGISLayerWhichShapes query:
select
encode
(AsBinary(force_collection(force_2d("geometri")),'NDR'),'base64') as
geom,"ogc_fid" from ( select geometri, * from general.country where
ST_Intersection(geometri,GeomFromText('POLYGON((12 0,18 0,18 84,12
84,12
0))',4326)) ) AS country where geometri &&
GeomFromText('POLYGON((-5.89995617157446

Anyone that can help with this?
