) As TableDefinition

Remarks
A QueryDescription object fully describes how a single database table or one or more database tables (specified by a valid SQL SELECT statement) should be represented as a Table or FeatureClass if the table is spatially enabled. Essentially, there are two flavors of QueryDescription. The first is created by GetQueryDescription(String). Given a table name (fully qualified or unqualified), it encapsulates all the important properties that describe the underlying single table (i.e., QueryDescription.IsQueryLayer returns false). The second flavor is created by GetQueryDescription(String,String). Given a valid SQL SELECT statement and a query layer name, it encapsulates all the important properties that describe the underlying query layer that is created from one or more tables (i.e., QueryDescription.IsQueryLayer returns true).
