            }
            finally
            {
                if (myOracleConnection.State == ConnectionState.Open)
                {
                    myOracleConnection.Close();
                }
            }


        }

如下是Oracle的存储过程

CREATE OR REPLACE PROCEDURE BZREPDB.FXA_MAINVALUEINFO (
   v_companycode    IN     CHAR,
   v_client         IN     CHAR,
   v_language       IN     CHAR,
   v_realdeprarea   IN     CHAR,
   v_fiscalyear     IN     CHAR,
   v_postperiod     IN     CHAR,
   v_returnvalue       OUT NUMBER
)
