Обсуждение: select from one table with help of another table
Hi, list,
I’m trying to get the fid (integer) of objects in table line where the geometry (postgis) is inside another geometry from another table (polygon),
But I would not like to get the objects with the highest fid inside the polygons of table buffered.
I’ve tried this:
SELECT fid FROM
"line" USING “polugon” AS b WHERE
ST_Contains(b.geom, "line".geom) AND "line".fid NOT IN (SELECT MAX("line".fid)
);
It complains about “USING” in line 2.
Anyone who knows how I should do it instead?
Kind regards,
Paul

What if a "line" is contained in more than one "polugon", and in one of these it has the highest "fid", but not in the others? Should that be included in the results? Yours, Laurenz Albe
