[Geoserver-users] Exception thrown on WFS query using "Between" filter

[Mark L. <Mar...@bm...>]

Hi all,

I'm passing the following query to the WFS:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" version="1.1.0"
service="WFS" xmlns:aa="http://myns/"
xmlns:ogc="http://www.opengis.net/ogc">
 <wfs:Query typeName="aa:feature_type">
  <Filter>
   <Between>
    <PropertyName>error</PropertyName>
    <LowerBoundary>0</LowerBoundary>
    <UpperBoundary>10000</UpperBoundary>
   </Between>
  </Filter>
 </wfs:Query>
</wfs:GetFeature>

When I try and do this I get an exception:

<ows:Exception exceptionCode="NoApplicableCode">
    <ows:ExceptionText>java.util.NoSuchElementException: Could not
aquire feature:org.geotools.data.DataSourceException: Error Performing

;apos;),&amp;apos;base64&amp;apos;), &amp;quot;error&amp;quot; FROM
&amp;quot;public&amp;quot;.&amp;quot;bathing_area&amp;quot; WHERE  LIMIT

;apos;),&amp;apos;base64&amp;apos;), &amp;quot;error&amp;quot; FROM

&amp;quot;public&amp;quot;.&amp;quot;bathing_area&amp;quot; WHERE  LIMIT
1000000
ERROR: syntax error at or near
&amp;quot;LIMIT&amp;quot;</ows:ExceptionText>
  </ows:Exception>

On inspecting the SQL in the exception report I can see that the WHERE
clause is left empty.  Surely it should be:

SELECT "id", encode(asBinary(force_2d("location"),'XDR'),'base64'),
"error" FROM "public"."feature_type" WHERE "error" BETWEEN 0 AND 10000
LIMIT 1000000

I can get around it with the obvious:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" version="1.1.0"
service="WFS" xmlns:aa="http://myns/"
xmlns:ogc="http://www.opengis.net/ogc">
 <wfs:Query typeName="aa:feature_type">
  <Filter>
   <And>
    <PropertyIsGreaterThan>
     <PropertyName>error</PropertyName>
     <Literal>0</Literal>
    </PropertyIsGreaterThan>
    <PropertyIsLessThan>
     <PropertyName>error</PropertyName>
     <Literal>10000</Literal>
    </PropertyIsLessThan>
   </And>
  </Filter>
 </wfs:Query>
</wfs:GetFeature>

Is this a known bug?

Many thanks,
