Discover if a workspace is a geodatabase or a feature dataset

CarlBeyerhelm — Thu, 25 Oct 2012 03:19:05 GMT

How can I discover if the os.path.dirname of a feature class is a feature dataset or a geodatabase? I need to generate a stand-alone frequency table of values from the feature class, but I can only create that stand-alone table at the geodatabase level, not at the feature dataset level.

Thanks...

...think you can use Describe for this. The datasetType property should return a string, FeatureDataset or FeatureClass, etc.

See the sample code here:

Hi Carl,

If you're iterating through feature classes within a geodatabase, it will only return stand-alone feature classes unless you specify a feature dataset within the arcpy.ListFeatureClasses function. Ex: (will only return stand-alon feature classes)

lstFCs = arcpy.ListFeatureClasses("*") for fc in lstFCs:     print fc

If you're not iterating using the arcpy.ListFeatureClasses function, you can use the describe method that Wayne mentioned. Ex:

dir = os.path.dirname(env.workspace + os.sep + fc) desc = arcpy.Describe(dir) if desc.dataType == "Workspace":     <remaining code>

OK, another rookie mistake on my part.

I'd been using the datasetType property without success, but the dataType property of os.path.dirname(feature class) distinguishes between a Folder, a Geodatabase, and a Feature dataset...which is what I needed.

Thanks to Wayne and Jake for nudging my pea-brain in the right direction...
