        public decimal GetPKNum(string tablename) 
        {
            switch (sqlType)
            {
                case "MSSQL2008":
                    parameters = new List<DbParameter>();
                    parameters.Add(new SqlParameter("@table_name", SqlDbType.VarChar, 50));
                    parameters.Add(new SqlParameter("@key_value", SqlDbType.Decimal, 9));
                    parameters[0].Value = tablename;
                    parameters[1].Direction = ParameterDirection.Output;
                    break;
                case "Oracle":
                    parameters = new List<DbParameter>();
                    parameters.Add(new OracleParameter(":tb_name", Oracle.ManagedDataAccess.Client.OracleDbType.Varchar2, 50));
                    parameters.Add(new OracleParameter(":key_value", Oracle.ManagedDataAccess.Client.OracleDbType.Decimal));
                    parameters[0].Value = tablename;
                    parameters[0].Direction = ParameterDirection.Input;
                    parameters[1].Direction = ParameterDirection.Output;
                    break;
                default: break;
            }
            IDBHelper dbhelper = DBFactory.createDBHleper();
            return dbhelper.RunProcedure(Utility.DB.PubConstant.ConnectionString,parameters, "up_get_table_key");
        }

IDBHelper dbhelper = DBFactory.createDBHleper();是后台創建了一個dbhelp文件，如果當時是Oracle數據庫 dbhelper 就為 OracleHelper文件

此oracle 存儲過程具有兩個參數，key_value 是返回參數out

Utility.DB.PubConstant.ConnectionString是數據庫連接字符串

"up_get_table_key"為存儲過程名稱
