PHP_Mapscript QueryByAttributes on PostGIS layer - bug or feature?

[Delfos, Jacob]

Hi List,

I'm trying to perform a QueryByAttributes operation on a PostGIS layer, but I get an error. Basically, it seems that the where clause being generated leaves out the attribute name and operator. Am I doing something wrong?

My code is:

   $gotResult = $oLayer->queryByAttributes("roadname","EMERALD RD",MS_MULTIPLE);

My PHP error is:

[19-Sep-2006 08:53:34] PHP Warning:  [MapServer Error]: prepare_database(): Error executing POSTGIS DECLARE (the actual query) statement: 'DECLARE mycursor BINARY CURSOR FOR SELECT roadname::text,asbinary(force_collection(force_2d(the_geom)),'NDR'),gid::text from roads WHERE (EMERALD RD) and (the_geom && setSRID( 'BOX3D(-149999998.5 -99999999,149999998.5 99999999)'::BOX3D,find_srid('','roads','the_geom') ))' <br><br>

It works if I do:

$oLayer->queryByAttributes("roadname","roadname like 'EMERALD RD'",MS_MULTIPLE);

Am I supposed to perform the QueryByAttributes operation differently for different data sources? It gets more difficult if I don't know in advance whether the type is text or number....
I searched the list and bugzilla for something similar, but couldn't find it. I'm using php_mapscript 4.8.3 (I tried using 4.10beta2, but all my mapfiles get invalid map extent errors for some reason).

Regards,

Jacob
