Detailed Description
The ISelectAggregate interface defines a Select command that handle selection of properties that include the use of aggregate functions. This command differs from the ISelect command in a number of ways. It handles selection of properties that are aggregate functions and supports selecting distinct property values. It also includes grouping criteria. The execute method returns an IDataReader which is not tied to a specific class. Unlike Select, ISelectAggregate does not include any locking functions.
