Howdy,
I need to CREATE VIEW of PostGis table.
My landusea_region table:
Field Type
gid int4
polygon_id int8
name varchar
langcode varchar
type varchar
city varchar
the_geom geometry
Early I try with simple VIEW
test=> CREATE VIEW only_pg_view AS SELECT * FROM landusea_region;
test=# \dv
List of relations
Schema | Name | Type | Owner
--------+------------------+------+----------
public | only_pg_view | view | postgres
(1 row)
PostGres-PostGis work fine, but when I try to use this view in mapserver with mapfile like:
LAYER
NAME LandUseA_region
# DATA LandUseA_region # original shape file -- work fine
CONNECTIONTYPE postgis
CONNECTION "user=pg_user password=pg_passwd dbname=test host=linux_box"
# DATA "the_geom from landusea_region" # work fine
DATA "the_geom from only_pg_land_use" # DOESNT WORK!!
STATUS ON
TYPE POLYGON
LABELITEM "name"
LABELMAXSCALE 50000
CLASS
TEMPLATE "land.html"
EXPRESSION ('[type]' = 'PARK (CITY/COUNTY)' )
NAME 'Urban park'
COLOR 0 210 0
LABEL
COLOR 25 120 50
# POSITION AUTO
END
END
END
Ive this:
Server error!
The server encountered an internal error and was unable to complete your request.
Error message:
Premature end of script headers: mapserv
If you think this is a server error, please contact the webmaster

I suppose need INSERT INTO geometry_columns table. I try to duplicate landusea_region record:
f_table_schema f_table_name f_geometry_column coord_dimension srid type attrelid varattnum
test landusea_region the_geom 2 -1 MULTIPOLYGON 17464 7
in
test only_pg_land_use the_geom 2 -1 MULTIPOLYGON 17464 7
but mapserver send me same Server error!
Environment
RH9
Mapserver4
Postgres 7.3.2
PostGis 0.5
Any suggest, sample?
Best regards
P.S.
Why I need to CREATE VIEW?
Because Ive geo-data in PostGres-PostGis table and miscellaneous data in other tables (and other remote db).
With a single VIEW I can map both of them.
