[mapguide-users] SetFilter filter function exceptions with sdf

[Jack Lee]

Hi Zak,
 
The function names are case sensitive. You should change "max(FeatId)" to "Max(FeatId)".

	Hi, 

	Has anyone had any problems using the built in filter functions for 
	the OSGeo.SDF.3.1 provider via the Mapguide 1.0.1 api? 

	The capabilities show they are supported but I get the following 
	exception when trying to use them to filter a Select operation: 

	An exception occurred in FDO component. 
	Function not supported 
	- MgFeatureServiceHandler.ProcessOperation line 83 file 
	c:\build_tux_area\mgdev_opensource\server\src\services\feature\FeatureServiceHandler.cpp 
	- MgOpSelectFeaturesSpatial.Execute line 115 file 
	c:\build_tux_area\mgdev_opensource\server\src\services\feature\OpSelectFeaturesSpatial.cpp 
	- MgServerSelectFeatures.SelectFeatures line 217 file 
	c:\build_tux_area\mgdev_opensource\server\src\services\feature\ServerSelectFeatures.cpp 

	Hopefully I'm just doing something stupid. Here's the php code: 

	$queryOptions = new MgFeatureQueryOptions(); 
	$queryOptions->AddComputedProperty("MyMax", "max(FeatId)"); 
	$featureClass = $layer->GetFeatureClassName(); 
	$featureReader = $featureService->SelectFeatures($featureSourceId, 
	$featureClass, $queryOptions); 

	The featuresourceid points to a session feature source which 
	references a valid sdf file. I've also tried going the SelectAggregate 
	route and I've tried other functions listed in the sdf capabilities 
	xml with similar results.
