Hi,

By reading the GML 3 standard it for example defines that Real and Number are of type xsd:double, and following that path to
http://books.xmlschemata.org/relaxng/ch19-77065.html

Restrictions
The decimal separator is always a point (.), and no thousands separator may be used.
Same restrictions to xsd:decimal http://books.xmlschemata.org/relaxng/ch19-77057.html

So at least in WFS 1.1.0 with GML 3 numbers with comma as decimal separator are wrong and if Mapserver ever generates such GML it feels like a bug for me.

Jukka,

The issue is not only the NLS format, which would govern the output and how the sql is interpreted, but there is also the issue of the lexer which is reading the xml request. And that would have to change also.

Its also unclear to me if XML / WFS allows other characters as a decimal character. I've yet to find any xsd or guide docs that indicate one way or the other.

Hi,

Without being a programmer I would like to see what would happen if this source file

https://github.com/mapserver/mapserver/blob/branch-7-0/maporaclespatial.c

would be edited around line 571-573:
cmd = "alter session set NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'";

by adding a new block for setting the decimal and thousands separators for output

cmd = "alter session set NLS_NUMERIC_CHARACTERS='. '";

I am not sure of the right syntax. This one works with SQL*Plus and set decimal points and space for thousands separator. I think that thousands should be without separators but the command seems to require two inputs.

Is there somewhere in the capabilities response where a user would declare what decimal separators are supported?

It seems to be a bug isn't?
Do you want me to open an issue?

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

It looks like whats happening is that's being converted into 3 Tokens and the oracle driver converts it into a number + comma + number.

The tokenizer is not treating that value as a single value.

here is the mapserver log with <ogc:PropertyIsEqualTo matchCase="true"><ogc:PropertyName>LONG_STAT</ogc:PropertyName><ogc:Literal>-61,8031</ogc:Literal></ogc:PropertyIsEqualTo>

msOracleSpatialLayerWhichShapes. Using this Sql to retrieve the data: SELECT ID, NO_STAT_CLIM, NO_STAT_FADQ, NOM_STAT, LATI_STAT, LONG_STAT, ALTI_STAT, D_DEB, D_FIN, TIMB_MAJ, USAG_MAJ, rownum, GEOM_POIN FROM (select * FROM SMDVDP_STAT_METE WHERE EXTRACT(YEAR FROM D_DEB) = 2014) WHERE  ( LONG_STAT = -61.000000,8031.000000 )  AND SDO_FILTER( GEOM_POIN, MDSYS.SDO_GEOMETRY(2003, :srid, NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),:ordinates ),'querytype=window') = 'TRUE'

The problem is
WHERE  ( LONG_STAT = -61.000000,8031.000000 )
