[OpenLayers-Users] postgis queries

[BMcBride]

Sure- you can use simple CQL_FILTER queries in your WFS request...

http://suite.opengeo.org/geoserver/wfs?service=WFS&version=1.0.0&request=GetFeature&typeName=usa:states&CQL_FILTER=STATE_NAME='New
York'&outputformat=json

Just make sure to tick the "Return bounding box with every feature" box in
your WFS settings in GeoServer.  

I use this technique for querying attributes and returning the results to an
ExtJS grid.  One of the columns in my grid is a "Map" link, which calls a
map.zoomToExtent function, based on the bbox values returned.  You may also
