Rishi,
>From a MAP file approach, you can use the FILTER tag inside of the LAYER
>section:
FILTER [string]
- This parameter allows for data specific attribute filtering that is
doneat the same time spatial filtering is done, but before any CLASSexpressions
are evaluated. For OGR and shapefiles the string is simplya mapserver regular
expression. For spatial databases the string is aSQL WHERE clause that is valid
with respect to the underlying database.
-
- For example: FILTER ([type]=’road’ and [size]<2)
In a static way, you will need to have two MAP files (one without FILTER and
another with FILTER) and you have to configure each project to point to the
right MAP file.
