Two-level Query

[Maurizio Esposito]

Hi list
I'm trying to solve this problem:
map server uses a layer "buildings" from Postgres, queryable and query
works fine.
I would query an element in the layer, a single building, and besides the
building_id and parcel number
I would like to query an other table in Postgres, say "homeowner" , with
columns building_id, homeowner_name,home_value
and show results in mapserver query.If possible not as a joined table, I'd
prefer a separate result with header and footer.

Any suggestion?
Another question: when using query map with option HILITE, selected items
are hilighted if are polygons but if are lines they don't. Why?
Missing something in mapfile?

Any help much appreciated, ty
