Hi all,
I can't load datas from a postgis view, the loader complains about no
uniques values and int4 type, however the view starts with SELECT
nextval('my_seq'::regclass)::integer AS gid, com.the_geom, ... (the
gid column is not listed in the error message) which works perfectly
if datas are
Dear Lionel,
AFAIK the view must contain a field being defined as primary key in the
underlying table, moreover this field must be of type integer.
The view must be defined in a way that every element (thus every
primary-key value) is unique. In case the view contains a join resulting
in
Hi Bernhard,
thanks to responding. I have modified the view to retrieve the gid
column form a table, which is a primary key with unique values, and
not from a sequence, but postgis provider complains again about no
unique values oO
Here is the table :

Dear Lionel,
I guess the problem is that you join spatial.commune at
residentiel.nrj_sourcesfixes. If this is a n:1 or n:m - join, gids
appear several times, thus gid is not unique (postgis provider tells
you). Try using residentiel.nrj_sourcesfixes' (or one of its underlying
tables')
Hi Lionel,
try a query like this:
select count(gid) from view group by gid having count(gid)1
to see if there is some duplicates.
Regards,
Andrea.
