I have an expression such as :- select (st_translate(graphics.utilities_dgm.the_geom, st_x(p_id.p_id.ithe_geom) + (ST_distance(p_id.p_id.the_geom, p_id.p_id.ithe_geom)
I need the option of either (+) or (-) after st_x(p_id.p_id.ithe_geom), depending on circumstance. At the moment I am writting two expressions. Is there a way of creating one expression that covers both circumstances? Bob
