Sure, you can do this. Key is to use mode=nquery rather than simply
query. You also have to how the mapserver builds a page when
multiple query results are present.
- sends web- header (if defined)
for each layer with query results
- sends layer- header (if defined)
for each result within a layer
- sends query- template
next result
- sends layer- footer (if defined)
next layer
- sends web- footer (if defined)
Sorta like building a sandwich.

Hi all
I have the query the layer one at a time using a unique
template for each query down. Is there a way to combine
a query for multiple layers into one template, so that
by clicking on a point backed by a poly you could get
the results from both in one shot. I have tried coding it
in the mapfile/page but it ignores one and answers the other.
thanks
