Overload List:

• ExecuteReader()

  Since OracleDataReader relies on an open connection to fetch data, ODP.NET does not close the connection after ExecuteReader() returns.

  ODP.NET sets the CommandBehavior to CommandBehavior.CloseConnection. As a result, the connection is closed once the reader is closed.

• ExecuteReader(commandBehavior)

  commandBehavior argument is ignored. The CommandBehavior.CloseConnection value is used.
