I have a relation representing all the counties in my country and the other one containing all the districts - e. g. each and every county is composed of several districts. How do I select them with spatial query? I tried with
select nazorp from kraje as k, orp_wgs as o WHERE ST_Within(o.geom,k.geom) AND
k.nazev = 'Liberecký'
but had wrong results returned (well, they are probably not wrong, they are just not what I expected them to be). ST_Within only returns districts that don't share a boundary with the county, but I need to get all the districts within the county. Is that possible? I haven't found any built-in function suitable for my needs yet.
