[mapserver-users] Mapserver filter/expression by DATE

Hello,

You can create your query through the commandline tool 'psql', and once 
you have that working you can test through the 'ogrinfo' commandline 
tool, using its '-sql' switch.  Then you can test through MapServer with 
the 'shp2img' commandline tool, by setting that query within the DATA 
statement of your mapfile layer.  See examples at 
http://www.mapserver.org/input/vector/postgis.html
