如何在c＃中使用NHibernate获取输出参数的mysql存储过程的值

Question

如何在c＃中使用NHibernate获取输出参数的mysql存储过程的值？

这里我的MySql存储过程如下：

CREATE DEFINER=`root`@`localhost` PROCEDURE `SaveEmployeeOutParamSP`(          
          IN Nameparam VARCHAR(30),
          IN Mobileparam VARCHAR(20),
          IN Sexparam BIT(1),
          OUT MaxIDOut INT,
          OUT TotalCOuntOut INT
)
BEGIN
INSERT INTO Test
    (
       Name,
           Mobile,
           Sex
    )
VALUES (
       Nameparam,
           Mobileparam,
           Sexparam
    );

   SELECT MAX(ID) FROM Test
   INTO MaxIDOut;

   SELECT COUNT(*) FROM Test
   INTO TotalCOuntOut;

END

这是我的NHibernate代码：

public void SaveGetEmployeeSP(EmployeeEntity employeeEntity)
    {
        IQuery query = NHSession.CreateSQLQuery("CALL SaveEmployeeOutParamSP (:Name, :Mobile, :Sex, :MaxIDOut, :TotalCOuntOut)");
        query.SetParameter("Name", employeeEntity.Name);
        query.SetParameter("Mobile", employeeEntity.Mobile);
        query.SetParameter("Sex", employeeEntity.Sex);
        query.SetParameter("MaxIDOut", "@MaxIDOut");
        query.SetParameter("TotalCOuntOut", "@TotalCOuntOut");
        var obj = query.UniqueResult();
    }

以上代码抛出的异常如下：

An unhandled exception of type 'NHibernate.Exceptions.GenericADOException' occurred in NHibernate.dll

Additional information: could not execute query

[ CALL SaveEmployeeOutParamSP(?p0, ?p1, ?p2, ?p3, ?p4) ]

  Name:Name - Value:2  Name:Mobile - Value:18  Name:Sex - Value:18  Name:MaxIDOut - Value:@MaxIDOut  Name:TotalCOuntOut - Value:@TotalCOuntOut

[SQL: CALL SaveEmployeeOutParamSP(?p0, ?p1, ?p2, ?p3, ?p4)]

所以任何解决方案 -
