Thanks Mike for having a look at it.
Your decimals are separated by a comma or a dot?

Re: [EXTERNAL] Re: [mapserver-users] Mapserver 7+oracle - wfs getFeature 
with filter on numeric field

Steve,

I tested this out with 7.1 with numeric type fields and it works for me as 
long as I don't use matchCase="false". That seems to kick it in to a 
string comparison. matchCase="true" and just PropertyIsEqualTo work fine.

In our metadata we use "gml_types"   "auto" when the database knows the 
types and explicit declarations (eg "gml_attributename_type"   "integer") 
when it doesn't work.

The key is that the field type has to report as a numeric type or the 
backend treats it as a string comparison.

Precision: we are using MS7.1 
Removing matchcase part makes oracle, and postgis, crash.
I have this error: 

<ows:ExceptionReport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<ows:ExceptionText>
msWFSGetFeature(): WFS server error. FLTApplyFilterToLayer() failed 
msOracleSpatialLayerWhichShapes(): OracleSpatial error. Check your data 
statement and server logs
</ows:ExceptionText> 

The problem might be the decimals? 
Here is the request 
<wfs:Query typeName="feature:SMDVDP_STAT_METE" srsName="EPSG:32198">

numeric field

can you try the same request without the "matchCase" part and report
back please?
