Hello!
I have two tables named myPtTable and myPolyTable on a PostGIS/PostgreSQL
8.3 server. I want to join the two table based on a spatial query has
following:
SELECT a.gid, b.gid, a.level, b.name a.the_geom
FROM myPolyTable a, myPtTable b
WHERE st_contains(a.the_geom, b.the_geom)
ORDER BY
Dear Francis,
afaik views work in QGIS now (i.e. Version 0.10), so your second view
SELECT a.gid, a.level, a.the_geom FROM myPolyTable a should definitely
work.
However your first view lacks a primary-key field, neither a.gid nor
b.gid are unique if you really have a n to m join.
What do you want
Hi Francis,

You could may get away with:
SELECT
(a.gid::int832)+b.gid::int8 as
