Thanks Daniel,
but
Nope, tried and failed :-(
Maybe it has something to do with the way I created the table:
CREATE TABLE testpoints
(
waarnemer character varying(40),
plaats character varying(40),
soort character varying(40),
aantal integer,
aantal2 character varying(40),
opmerking character varying(200),
the_geom geometry,
CONSTRAINT testpoints_pkey PRIMARY KEY (oid),
CONSTRAINT enforce_dims_the_geom CHECK (ndims(the_geom) = 2),
CONSTRAINT enforce_geotype_the_geom CHECK (geometrytype(the_geom) =
'POINT'::text OR the_geom IS NULL),
CONSTRAINT enforce_srid_the_geom CHECK (srid(the_geom) = 28992)
)
WITH OIDS;
ALTER TABLE testpoints OWNER TO postgres;
I wanted to have a table in which I had an auto incrementing id-column.
This was the way to do that (according to mr Google :-) )
If I look at the table with pgAdmin III there is a column 'oid' with the
id's in it. If I look with QGIS there is a column 'id'...
But if I do:
SELECT
a.attnum,
a.attname AS field,
t.typname AS type,
a.attlen AS length,
a.atttypmod AS lengthvar,
a.attnotnull AS notnull
FROM
pg_class c,
pg_attribute a,
pg_type t
WHERE
c.relname = 'testpoints'
and a.attnum > 0
and a.attrelid = c.oid
and a.atttypid = t.oid
ORDER BY a.attnum
I don't see the oid column either....
It probably has something to do with the special meaning of an oid
column in postgresql???
I will try to update my mapserver to the newest version (working with
4.8.3 now...) and see if that works.
Other solution: add my own id's of use a sequence instead of this
autoincrementing... Any postgresql guru's around?
Thanks, Richard
