The OpenAccessDataReader object is a forward-only cursor that retrieves read-only records from a database. Performance is better than OpenAccessDataAdapter, but the result set cannot be modified.
For information about the properties and methods supported, refer to the .NET Client’s online help and the Microsoft .NET Framework SDK documentation.
Note: To avoid statements or cursors being kept open on the database server, be sure to close or dispose each OpenAccessDataReader object as soon as you are finished reading with it.
