Detailed Description

The IDataReaderImp class is a concrete implementation class for IDataReader. The IDataReader interface provides a forward-only, read-only iterator for reading relational table data. A reference to an IDataReader is returned from the SQLCommands ExecuteReader method. The initial position of the IDataReader interface is prior to the first item. Thus, you must call ReadNext to begin accessing any data.
