itemnquery mode and postgis help

Fri Jan 14 10:53:00 PST 2005

Hello,

I'm having trouble getting info using itemnquery cgi mode. I have found many examples that use shapefiles but I have yet to see one that uses postgis. So, I'm having a bit of trouble getting info from the db.

Here is how I run the command:
./mapserv QUERY_STRING="mode=itemnquery&map=/mapfiles/idcdev_canada-itemnquery.map&imgext+3674226.39765+-183134.22738+3676417.48504&mapsize=688+434&imgbox=195+11+570+401&source=TIG600&qlayer=wells&map_wells_filter=%2F100032300505W500%7C200B067H082G0700%2F&uwi=100032300505W500&uwi=200B067H082G0700&layers=wells+wells-selected"

It comes back with:
Content-type: text/html

<HTML>
<HEAD><TITLE>MapServer Message</TITLE></HEAD>

<BODY BGCOLOR="#FFFFFF">
msQueryByAttributes(): Query error. No query expression defined. <br>

Here is my mapfile (BTW, nquery works with this mapfile - I've been using http://maps.dnr.state.mn.us/mapserver_demos/tests40/itemquery/case2.map as an example):

NAME TEST1

END

   DATA "the_geom from (select oid, to_date(main_well2.spud_date, 'YYYY-MM-DD') as pretty_spud_date, to_date(main_well2.rig_release_date, 'YYYY-MM-DD') as pretty_rig_release_date, prettyuwi(main_well2.uwi) as prettyuwi, well_status(plot_symbol) as well_status, * from main_well2) as new_table using unique oid"
   TEMPLATE "./idcdev_wells.html"
   PROJECTION
    "init=epsg:4269"
   END
END

END

Any help would be appreciated
