Hi
I have a table consisting of 858 points which spatially covers a geometry.
I want to pick out the points that are spatially within that geometry.
I am using the following but it returns a null (empty?) value.
select st_astext(graphics.point_grid.the_geom)
from graphics.point_grid, library.dgm_process
where library.dgm_process.process_number = '1'
and st_within(graphics.point_grid.the_geom, library.dgm_process.the_geom);
Any thoughts would be appreciated.
Bob
