[postgis-users] Get Coordinate Line Or Polyline Or Point

[Obe, Regina]

One thought
 
SELECT REPLACE(REPLACE(REPLACE(astext(the_geom), geometrytype(the_geom),
''),'(',''), ')','') as coords
FROM mytable
 
If you know the geometrytype already, might be faster to hard-code that.

Hope that helps,
Regina
