[postgis-users] Returning polygons if any of a polygon input points lie in the polygons

Rémi:  Yes, that worked perfectly.  Thanks!  My input poly will be stored in another database (maybe just another table).   It would be nice to perform the query all on 1 line (get the poly and use it for the query), but I can query the first table first to get the input poly, then use that for the 2nd query without too much difficulty.
Thanks again for the responses!

Something like this?

SELECT  zone,gid,state,name,ST_Asgeojson( geom ) 
FROM polys 
WHERE ST_Overlaps(ST_GeomFromText('POLYGON((-109 42,-108 42, -108 43; -109 43, -109 42))', 4269), geom)=TRUE;

Hello, Maybe I don’t understand your problem very well but I think your query for points should work with a polygon using ST_GeomFromText (http://www.postgis.org/docs/ST_GeomFromText.html) for your input polygon or a subquery if it stored into your DB. Hugues. De : postgis-users-bounces at lists.osgeo.org [mailto:postgis-users-bounces at lists.osgeo.org] De la part de Joseph Spenner

Objet : [postgis-users] Returning polygons if any of a polygon input points lie in the polygons Hello, I'm trying to perform a query which will return any polygons which have any points in common with an input polygon. So, if I have Polygon A.In my database, I have several other polygons stored. I want to submit a query with Polygon A as the input, which will return all of the polygons in my database which have any points in common with Polygon A. Can this be done?
I found this:http://postgis.net/docs/ST_Overlaps.html But from what I can tell, it only returns a T or F.   I need to fetch the actual polygons if T. I'm currently able to query with points as input: select zone,gid,state,name,ST_Asgeojson( geom ) from polys where ST_Intersects(ST_PointFromText('POINT(-109 42)', 4269), geom);

But now I have a need to use polygons as input.

Any help would be great.

Thanks! Regards,Joseph Spenner
