Remarks

The OpenFeatureQuery can be used to open a virtual feature class whose definition is based on a QueryDef created using the CreateQueryDef method. The QueryDef can involve multiple tables as long as one of them is a feature class; the resulting virtual feature class can be used to construct a feature layer that can be added to a map. The shape column is required as part of the SubFields parameter of the QueryDef.
