Detailed Description

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