[mapguide-users] Select Distinct QueryOption or Filter?

[Dave Wilson]

Not all providers support distinct.

You need to check the GetCapabilities for each provider via
http://localhost/mapguide/mapagent/index.html under FeatureServices -
GetProviders will list your providers. Then using GetCapabilities it
will indicate if it supports Distinct. Distinct is a flag in the
QueryOptions that can be set if I recall correctly.

Subject: [mapguide-users] Select Distinct QueryOption or Filter?

All,
Is there a way to query DISTINCT Features when using the
FeatureService.SelectFeatures() or SelectAggregrate() with the
QueryOptions, or possibly is there a "Distinct" filter option available.
Any help or code/source documenting this would be helpful.

Thanks,

-scott
