[postgis-users] PostGIS table doesn't show up in QGIS

[Ben Madin]

Puneet,

Not uncommon problem - QGIS looks in the Geometry_columns table - you might want to check that the geometry column is registered in this table. If not you can run :

SELECT Populate_Geometry_Columns(); -- for all tables

or

SELECT Populate_Geometry_Columns('public.myspatial_table'::regclass); -- for myspatial_table

http://postgis.refractions.net/documentation/manual-1.5/Populate_Geometry_Columns.html

Note that using AddGeometryColumns() does this, but it can be corrupted. Importing tables doesn't do this automagically.

cheers

Ben
