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

The matchCase triggers a string comparison. matchCase doesn't seem to make sense for a number.

That being said, I can look into the specific case of matchCase and a numeric comparison and make sire that it isn't used.

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

Is there a documentation that says that it is not?
Folks from gdal list also think that it is not supported...I guess you are right. But as I said on the gdal list, many countries are using a comma as a decimal separator....what other people on the planet do?
Anyway the comma is another problem that I try to manage later......

For now, We have an application that generate and launch spatial queries on WFS, matchCase=false by default. Before modifying the code I want to understand what is going on....
It seems,when using numeric value, that matchCase as no impact in PostGIS, but it is important in oracle to be set to true

gml_type = auto, returns double in postgis and oracle, so that is fine
A WFS getFeature with the operator PropertyIsEqualTo AND matchCase=false
using this value -64.225
PostGis: it works
Oracle (from mike's test): it fails...matchCase must be set to true

A WFS getFeature with the operator PropertyIsEqualTo AND matchCase=false
using this value -64,225
PotsGis: not tested
Oracle: it fails...matchCase must be set to true

Is there a reason why, with oracle, matchCase should be set to true when using numeric value, or that could be fixed?

Steve

Its not clear to me that commas as the decimal separator is supported in XML/GML. I can't find any documentation to indicate that it is. Can you point some out to me?

In any event, I didn't test with comma decimal separators.

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

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?

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

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