If you are using MapServer 5.0 or the brand new 5.2 then you can
probably use attribute binding, which allows you to specify an
attribute in your data as the source for various parameters in the map
file. For instance, if you have a field in your database called
point_size that has a size value then you can do this:
SIZE [point_size]
You can also bind to COLOR and most other attributes inside STYLE and
LABEL. I just went to look for documentation on attribute binding and
I can't seem to find anything beyond the original rfc (http://mapserver.gis.umn.edu/development/rfc/ms-rfc-19
) so if you are running into trouble, don't hesitate to ask the
developers :)

Hi all! I'm firing up a mapserver for our company these days.
Mapserver successfully connects to Postgres, and draws points from
my database. But I need to change some parameters, such as colour
and size of points on-the-fly, depending on the duration of their
existence. Is there a way to make Mapserver to pick size and colour
of points from Postgres, too?
