[postgis-users] More than one row returned...

[Martin Fafard]

Hi

I have this query

delete FROM original o
WHERE st_intersects (o.the_geom,  (select (st_intersection (c.the_geom, 
o.the_geom))
  from original o, cutter c
  group by c.the_geom, o.the_geom));


to delete portions of lines in a table that intersect with other lines 
in another table.
Error: the subquery return "more than one row...". Don't know why!

Thanks
