Your view is defined by a sql select so you should try to leave this select as is except for the where clause where you could add something like : and c.relname not like 'your_table_name' I tried it with one of my table and this was ok, the table disappeared from the geometry_columns view Hugues.

All of them have their own geometry column registered into the geometry column set by postgis My problem is that the main table (a huge one with mixed geometry data type) has its own geometry column. When qgis starts the connection to this db automatically looks into the geometry column set and find the geom.column relative to the main table, so it searches that table for the geometry type and take a lot of time to do it... How can I hide this geometry column? Thnx Pietro 2012/10/22 Francois Hugues [via PostGIS] <[hidden email]> Hello "This because I cannot remove the entities geometry column unless I remove the entity table first. And if I don't remove (or make invisible to qgis if possible) the entities geometry column it slow down the qgis connection." Did you try to edit the view, using the where clause to exclude the tables you don't want to be seen by postgis ?

By the way If my technique works, is it still better to explode the "entities" table in one of this cases: a) single layers b) same kind of geometries in both cases table permanent. This because I cannot remove the entities geometry column unless I remove the entity table first. And if I don't remove (or make invisible to qgis if possible) the entities geometry column it slow down the qgis connection.

What's wrong is that the "geometry_columns" table should be a view, in PostGIS-2.0. If it is a view, your DELETE and INSERT and UPDATE to it should have no effect. Can you verify this first ? The DELETE/INSERT/UPDATE commands all return the number of affected rows. If PostGIS is correctly installed you should alwyas get 0, no matter what you try to insert/delete/update. Also check: select relkind from pg_class where relname = 'geometry_columns'; --strk;  http://www.cartodb.com - Map, analyze and build applications with your data                     ~~ http://strk.keybit.net _______________________________________________ postgis-users mailing list [hidden email] <http://user/SendEmail.jtp?type=node&node=5000684&i=0> http://postgis.refractions.net/mailman/listinfo/postgis-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://postgis.17.n6.nabble.com/How-to-make-some-geometry-column-visible-to-Qgis-tp5000570p5000684.html To unsubscribe from How to make some geometry column visible to Qgis, click here.
