[mapserver-users] msQueryByFilter(): Search returned no results.

[Michal Šrédl]

Hi all,

I am trying to use FES filter for WFS layer and get no result, even
thought I should get one.

In my browser, I request

http://localhost//cgi-bin/ows?&REQUEST=GetFeature&VERSION=1.1.0&SERVICE=WFS&TYPENAME=typ&FILTER=<ogc:Filter
xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsEqualTo><ogc:PropertyName>ZVER</ogc:PropertyName><ogc:Literal>2</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter>

and get

<wfs:FeatureCollection
xmlns:ms="http://mapserver.gis.umn.edu/mapserver"
xmlns:gml="http://www.opengis.net/gml"
xmlns:wfs="http://www.opengis.net/wfs"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://mapserver.gis.umn.edu/mapserver
http://127.0.0.1/cgi-bin/ows?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=typ&OUTPUTFORMAT=text/xml;%20subtype=gml/3.1.1
http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
<gml:boundedBy>
<gml:Null>missing</gml:Null>
</gml:boundedBy>
</wfs:FeatureCollection>

even though I do know, that features with ZVER=2 do exist.

In the mapserver log file, I get

[Wed Aug 24 14:48:52 2011].296607 msQueryByFilter(): Search returned
no results. No matching record(s) found.
[Wed Aug 24 14:48:52 2011].296747 mapserv request processing time
(msLoadMap not incl.): 0.002s
[Wed Aug 24 14:48:52 2011].296764 msFreeMap(): freeing map at 0x2783120.
[Wed Aug 24 14:48:52 2011].296773 freeLayer(): freeing layer at 0x278b570.

I have checked http://mapserver.org/errors.html#id2 with similar error
"msQueryByPoint: search returned no results" and tried to create a
simple template:

<!-- MapServer Template -->
<tr>
  <td>[lrn]</td>
  <td>[ZVER]</td>
</tr>

but with no effect.

In the mapfile, there is

LAYER
  NAME "typ"
  METADATA
    "wfs_title"    "Typologie" ## REQUIRED
    "gml_featureid" "CISLO" ## REQUIRED
    "gml_include_items" "all"  ## Optional (serves all attributes for layer)
    "gml_types" "auto"
    "gml_geometries" "msGeometry"
    "gml_msGeometry_type" "polygon"
  END
  DATA typ.shp
  TYPE POLYGON
  STATUS ON
  PROJECTION
    "init=epsg:102067"
  END
  DUMP TRUE           ## REQUIRED
  CLASS
    NAME "Typ"
    STYLE
      COLOR 0 0 155
      OUTLINECOLOR 120 120 120
    END
    TEMPLATE "templates/typ_zver.html"
  END
  DEBUG 5
END # Layer

What is wrong with my FES filter? How can I make it to run?

Thanks a lot,

Michal
