Hello, I'm new to postgis/postgresql. I was wondering if anyone could tell me how to make a function out of this sql query:
WITH RECURSIVE flow(gid, geom) AS ( SELECT e.gid, e.geom FROM electric_line e, fuses f WHERE ST_DWithin(ST_AsText(e.geom)::geometry, ST_AsText(f.geom)::geometry, 0.01) AND f.gid=' . $_GET['fuse'] . ' UNION ALL SELECT n.gid, n.geom FROM electric_line n, flow f WHERE ST_DWithin(ST_EndPoint(f.geom),ST_StartPoint(n.geom),0.01) ) SELECT *, ST_ASGeoJSON(ST_Transform(geom,4326),6) AS geojson FROM flow; I'd like to make a function flow(gid) Thanks, Jon
