queryByAttributes and postgis

[Francesco]

Hello, I have a problem when using mapserver  with postgis  to perform a 
queryByAttribute on a layer.
The problem disapear when using the same data with shape files.

The error returned by teh mapscript middleware is:

<<<<<Start of the error:

Postgresql reports the error as 'ERROR:  invalid input syntax for 
integer: "3523 AND cod_concio = 6087 AND cod_concio = 6092"
'<br><br>

More Help:<br><br>

Error with POSTGIS data variable. You specified '<check your .map 
file>'.<br>
Standard ways of specifiying are : <br>
(1) 'geometry_column from geometry_table' <br>
(2) 'geometry_column from (<sub query>) as foo using unique 
<column name> using SRID=<srid#>' <br><br>

Make sure you put in the 'using unique  <column name>' and 'using 
SRID=#' clauses in.

The parameter given to the queryByAttribute was:

Jun 01 14:35:50 Seagull [debug] clickmgr->performquery: 2st step: do the 
query (queryItem = cod_concio, queryString = 3523 AND cod_concio = 6087 
AND cod_concio = 6092)

I tried different string such as:
3523' OR cod_concio = '6087' OR cod_concio = '6092   (OK, only postgis)
3523 OR cod_concio = 6087 OR cod_concio = 6092      (that does not work)
([cod_concio] in '3523,6087,6092')                                       
                               (works on shape)
('[cod_concio]' in '3523,6087,6092')                                    
                                 (works on shape)
([cod_concio] = 3523 OR [cod_concio]=6087 OR [cod_concio] = 6092')      
      (works on shape)

Have any idea?
