Re: [mapserver-users] display only one district
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.

In other threads of this list, it was suggested to use a subquery in DATA instead of using FILTER, when postgis is used as a datasource. http://mapserver.org/fr/input/vector/postgis.html#data-access-connection-method If you want to use only one mapfile than runtime variable substitution can be used Carlos Ruiz boolean10...@yahoo.com@lists.osgeo.org Envoyé par : mapserver-users-boun...@lists.osgeo.org 2015-03-20 14:53 Veuillez répondre à Carlos Ruiz boolean10...@yahoo.com A rishi rish...@gmail.com, jmcke...@gatewaygeomatics.com jmcke...@gatewaygeomatics.com, mapserver-users@lists.osgeo.org mapserver-users@lists.osgeo.org cc Objet Re: [mapserver-users] display only one district 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 done at the same time spatial filtering is done, but before any CLASS expressions are evaluated.
