Alexandre,
Thank you very much. Of course, it was operator error!
I was writing a quick query for a demo and not to solve a real problem, so
I hadn't really thought through the issue with unique results. Adding
DISTINCT made it work as expected.
A great enhancement to DB Manager would be some
Hello David,
Can I assume that you use fires.id as unique integer value column in
DBManager to load the layer?
Because with your query you will likely get repeated values for fires.id.
That is, each fires feature will appear as many times as lakes within 1000
meters.
If that's what you want, you
Thanks for the response Alexandre.
Here is the query:
SELECT fires.id, fires.inci_no, fires.descript, fires.geom
FROM lab.mpls_fires_2014 fires
INNER JOIN lab.mpls_lakes lakes
ON ST_DWITHIN(fires.geom, lakes.geom, 1000)
When I add ST_GEOMETRYTYPE(fires.geom) to the query, the value is
St_M
Can you please show your sql query?
Notice that if your query result in different geometries, qgis won't be
able to choose a geometry type for the layer. I advice you to Check your
results with St_GeometryType().
Best regards,
Alexandre Neto
