In PostGIS 2.0, I am seeking an efficient way to create a spatially enabled view that is viewable in QGIS.
I followed the context of Part 2 of @Mike Toews answer to How to create a table from existing tables (applying new schemas) in postgis DB?, and the view shows up as a point layer (in my case) in the "Add PostGIS Layers" dialog. But after creating the view and spatially enabling it, I received the following error when trying to add the view to QGIS:
You must select a table in order to add a layer
Can someone explain why the spatial view will not load into QGIS, and what I need to do in order to make it loadable as a layer in QGIS?
I'm currently using QGIS v1.8 from the OSGEO installer
I view is built from the geonames database, loaded into PostGIS. The geoname table/spatial data can be selected/viewed in QGIS just fine.
When I try to select the "mt_view", QGIS sees the view in the dialog, but won't let me select it. It gives a dotted box around the area, but does not highlight and select the view.
I just noticed that when I run my first query:
CREATE OR REPLACE VIEW data.test AS
SELECT * FROM data.geoname
the view shows up in the QGIS Add Layer Dialog, but is unselectable. Then when I run:
I get the result of "0", where according to the documentation, I think it should be returning "1".
