调用
conn.Open(); OracleCommand cmd = new OracleCommand(); cmd.CommandType = CommandType.StoredProcedure;//设置cmd的类型为存储过程 cmd.CommandText = "EMP_COUNT"; OracleParameter param = new OracleParameter("paraminout", OracleType.VarChar, 20); param.Direction = ParameterDirection.InputOutput; cmd.Connection = conn; cmd.Parameters.Add(param); cmd.ExecuteNonQuery(); MessageBox.Show("Get PROCEDURE return:".ToLower() + param.Value.ToString()); |
存储过程
create or replace PROCEDURE EMP_COUNT(paraminout in out varchar2) AS V_TOTAL NUMBER(10); BEGIN SELECT COUNT(*) INTO V_TOTAL FROM EMP; paraminout := V_TOTAL; DBMS_OUTPUT.PUT_LINE(V_TOTAL); END; |
