Yes, I do to both questions. normally, In PostGIS you get the x and y of each point shape using the x(geometry) and y(geometry) functions. But In our database, the geometry is in the field called the_geom, so you would get the x and y for each point using x(the_geom) and y(the_geom). So the query below works except it is very sloooooooow. SELECT str_num || ' ' || name as full_address, > > > distance(the_geom,'POINT(2227284.1963667543 > > > 1435389.6730164126)'::geometry) as dist > > > FROM address > > > ORDER BY dist limit 1 It is only when I try using the overlap operator as a where predicate that it crashes. >From: Tyler Mitchell <TMitchell <at> lignum.com> >Reply-To: PostGIS Users Discussion <postgis-users <at> postgis.refractions.net> >To: PostGIS Users Discussion <postgis-users <at> postgis.refractions.net> >Subject: Re: [postgis-users] Bounding Box Query >Date: Mon, 29 Mar 2004 09:15:53 -0800 > >Do you have the x,y coordinate pair in a table in the database? >Do you have the road data in a table too? > >postgis-users-bounces <at> postgis.refractions.net wrote on 03/29/2004 08:40:07 >AM: >(Continue reading)
