[mapserver-users] attribute query error

Wed Feb 13 11:11:10 PST 2002

Hi Friends,

           Thanks for your help, 

Here is the link i am passing to display the attribute queries.

http://208.163.164.119:6500/cgi-bin/mapserv?map=../htdocs/pams1/pams.map&lay
ers=flightline&mode=itemnquery&zoomdir=0&imgxy=585 295&imgext=300434 -148033
322234 1655445&zoomsize=2&mapext=-252600 -148033 274400
165545&qlayer=flightline&map_flightline_header=mapdisplay.html&map_flightlin
e_template=zoomto.html&item=Pams_code&value=^204A$&item=Pams_code&value=^218
A$

Pams_code is the attribute in flightline shape file.

msQueryByAttributes(): General error message. No query layer defined. 

I am using mapserver 3.5, windows 2000, apache.

Can you tell me whats wrong in that link. 

Is there any examples in mapserver site for attribute queries?.
where i can found these  documentation.

Thanks,
Anwar

It's not a mapfile problem, rather a problem with the CGI query. With
attribute queries you set the qlayer variable so the server knows which
layer to process.
