Hi, I have some geometries where every element is a GeometryCollection like this three examples:
GeometryCollection(MultiLinestring empty, MultiLinestring(( x1 y1, ... , xn yn))) ; GeometryCollection(MultiLinestring(( x1 y1, ... , xn yn)), MultiLinestring(( x1 y1, ... , xn yn))) ; GeometryCollection(MultiLinestring(( x1 y1, ... , xn yn)), MultiLinestring empty) ; These are all geometry-collection where every collection is composed of two element and the first or the second could be a "geometry empty". I don't know how to detect if the first or the second element are "geometry empty". I try with to apply the ST_Dump, but it seem to ignore the "geometry empty" so it return only one record. Thx, Andrea. -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòù -----------------
