Error on Itemnquery with PostGIS-layer

Tue Aug 21 07:41:40 PDT 2007

How could I add columns to DATA statement ?

I think my mistake is in the query-URL:

this one works on Windows with shapefile-data but not on Linux with PostGIS
(anything else works fine)
http://myServer.com/cgi-bin/mapserv?&map=/home/harry/Mapfiles/MyMap.map&mode=itemnquery&qlayer=City-Database&qitem=name&qstring='London'

changing the syntax to this (what should be the same than above)
http://myServer.com/cgi-bin/mapserv?&map=/home/harry/Mapfiles/MyMap.map&mode=itemnquery&qlayer=City-Database&qitem=name&qstring=('[name]'='London')

results in 

msQueryByAttributes(): Search returned no results. No matching record(s)
found. 

at least no error but 'London' is definetly in the database and I tried with
upper case/lower case,...

The PostGIS-databasename is 'geonamesallppl' the tablename is 'name' and
also the column-name is 'name'.

Any ideas what I am doing wrong ??

Thx, Harry

This is my template-file (if it plays a role)

<html>
  <head><title>Sample Template</title></head>
  <body>
     <li> Name is [NAME]
     <li> Population is [POPULATION]
     <li> Code is [CODE]
<tr>
  <td>[lrn]</td>
  <td>[NAME]</td>
</tr>

  </body>
</html>
