[mapserver-users] TinyOWS and the logical operators

[Andrea Peri]

mmh...

Hi,

'm try-ing to check the logical operator  but they don't seem work.

If the AND operator is supported this mean that I'm wrong something.

This request will get the results from a query with filter NAME="FIRENZE".

http://web.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=infrastrutture:rt_infr_idstrade_rt_bb&propertyName=geometry,dug,toponimo,den_estesa,tipo_prop,cod_istat,comune&sortBy=dug+A,toponimo+A&Filter=%3CFilter%20xmlns:wfs=%22http://www.opengis.net/wfs%22%3E%3CPropertyIsEqualTo%3E%3CPropertyName%3Ecomune%3C/PropertyName%3E%3CLiteral%3EFIRENZE%3C/Literal%3E%3C/PropertyIsEqualTo%3E%3C/Filter%3E

And the logs report correctly the filter used:

[Sun Oct 14 11:51:50 2012] [SQL] SELECT ST_xmin(g.extent),
ST_ymin(g.extent), ST_xmax(g.extent), ST_ymax(g.extent) FROM (SELECT
ST_Extent(foo.the_geom) as extent FROM (  (SELECT
ST_Transform("geometry"::geometry, 3003) AS "the_geom" FROM
iternet."itnt_stradebb"  WHERE "comune" = 'FIRENZE' ORDER BY "dug"
ASC,"toponimo" ASC LIMIT 500) ) AS foo) AS g


Now I try to call the same request with a double filter:
NAME="FIRENZE" AND TIPO_PROP="Comune"

I build it following a sample from mapserver docs.

http://web.regione.toscana.it/wfsvector/com.rt.wfs.RTmap/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=infrastrutture:rt_infr_idstrade_rt_bb&propertyName=geometry,dug,toponimo,den_estesa,tipo_prop,cod_istat,comune&sortBy=dug+A,toponimo+A&Filter=<Filter
xmlns:wfs="http://www.opengis.net/wfs
"><AND><PropertyIsEqualTo><PropertyName>comune</PropertyName><Literal>FIRENZE</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>tipo_prop</PropertyName><Literal>Comune</Literal></PropertyIsEqualTo></AND></Filter>

But this request don't return any results.
Seeing the log it report that the query has the "where" filter empty:

[Sun Oct 14 11:55:38 2012] [SQL] SELECT "ogc_fid",ST_AsGML(3,
ST_Transform("geometry"::geometry,3003),8, 23) AS "geometry"
,"col_0","cod_top","comune","siglaprov","cod_com","cod_istat","dug","toponimo","cod_reg","den_estesa","tip_prp","tipo_prop","cod_prp","cls_amm","den_breve","data_elab"
FROM iternet."itnt_stradebb" WHERE  ORDER BY "dug" ASC,"toponimo" ASC LIMIT
500

so nothing is find.

If the AND operator is supported from TinyOWS, this mean that I'm wrong
something else.

Any hint is welcome

Thx,

Andrea.
