One of the ParameterDirection values. The default is Input.

ExceptionCondition

The property was not set to one of the valid ParameterDirection values.

If the ParameterDirection is output, and execution of the associated OracleCommand does not return a value, the OracleParameter contains a null value.

Output, InputOut, and ReturnValue parameters returned by calling ExecuteReader cannot be accessed until you call Close on the OracleDataReader.

The following example creates a OracleParameter and sets some of its properties.
