Does the error message you're receiving say "No matching records found, =
layer
and area of interest do not overlap"? If it does, then check the extents =
of
your query layer (country) against the extents in your map object. Does =
your
query layer fall within the map file extents? When I received the =
following
error message: msQueryByAttributes(): Search returned no results. No =
matching
record(s) found, layer and area of interest do not overlap, the cause of =
the
error for me was incorrect map extents in the map file object.
Do you have separate query and display layers in your map file? If you =
don't
(but rather have a single query and display layer), then maybe you need
separate layers. The example below has a separate display layer because =
the
query layer doesn't actually display anything, it's used simply to =
define the
map extents. This is because there are times when the mapping =
application
needs to display all polygons in the display layer, without any query
process. Also, in this particular case the query dataset is actually a
different dataset to that used for display, due to the nature of the =
data. If
you have only one layer, which doubles as the query and display layer, =
you
may receive a "No matching records found" if you try to display all =
features
without sending any query information, since MapServer will perform the =
query
without any query information, and so return no results. However, I =
don't
think this is your problem, as you are sending query information.=20

Hi,=20
I am experiencing a problem with (Itemquery, Itemnquery). Regardless of
syntax I get the message "No Matching Records found".=20
Mapserver : 4.0
OS : Windows 2000 Professional
=09
My URL string follows:
...mode=3Ditemnquery&qlayer=3Dcountry&qstring=3D('[CNTRY_NAME]'+EQ+'NAMIB=

I have tried all sorts of combinations including upper/lower case field
names, but it doesnt seem to make any difference.
Any help in this regard would be much appreciated.=20
Kind Regards
