query

[N Zhou]

Hi,

I have a problem of querying layer(s). My query URL is:
http://myhost/cgi-bin/mapserv?mode=nquery&map=/data/ZhouWFS.map&imgext=477185+424885.5+591620+539320.5&imgbox=1+1+399+399&imgsize=400+400&layers=ngs1

There should be some query results and I did have the results using
PHP/MapScript classes. But I actually got from the URL query:
      msQueryByRect(): Search returned no results. No matching record(s)
found.

I also tried to query a point:
http://myhost/cgi-bin/mapserv?mode=query&map=/data/ZhouWFS.map&imgext=477185+424885.5+591620+539320.5&imgbox=150+187&imgsize=400+400&layers=ngs1

But I still got result message as:
     msQueryByPoint(): Search returned no results. No matching record(s)
found.

Is there any error of the URL query? I noticed similar discussions last year
but I'm still confused.

Thank you very much!

N. Zhou
