AW: [Mapserver-users] execute two querys at the same time

[Nicole Bömeke]

Hello Jan,

I don't know wich selection will be needed befor someone sends a request.
I'm using the mapserver to display the route from a starting point to an
ending point specified in the request. All combinations of points in my
layer are valid - that makes 365816 different possibilities for the
selection.
Therefor I use a query to mark the selection.

See: http://www.stadtinfokoeln.de Bus & Bahn - Fahplanauskunft KVB

(specify a station i.e. "Köln - Zoo" to "Köln - Hauptbahnhof" and choose
"Karte")

Now I want to mark each part of the route in a different color depending
on the means of transport (bus, train, car, ...) to be used.

Nicole,

Aren't you making it very difficult for yourself? If you just want to
display assorted selections with different colors, you can use CLASS
expressions within layers. To display selections from several layers,
you can define classes for each layer and display all layers
transparently (see OUTPUTFORMAT). Queries are only needed when you want
to process additional data from the selected items. Templates for these
can be provided at CLASS and LAYER level.
