[mapguide-users] Select Distinct QueryOption or Filter?

[Scott Reisdorf]

Thanks Dave.
I am using SDF3, and from the provider it says it supports 
SelectDistinct (<SupportsSelectDistinct>true</SupportsSelectDistinct> )
I now dont know how to set the Flag in the QueryOptions to be Distinct.  
Looking at the API and the code, it does not appear that the Distinct 
option is available on the QueryOptions.  Does anyone know how to select 
Distinct Features using the FeatureService?

Thanks,
-scott
