[mapserver-users] [EXTERNAL] Re: 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:

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

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