Question

我有这个存储过程：

CREATE PROCEDURE getManagerSalary 
(
@Emp_id         INT,
@ManagerSalary  MONEY OUTPUT
)
AS
SELECT @ManagerSalary = es.Salary
FROM [outdoorparadise].[dbo].[Employee] AS e 
INNER JOIN 
    [outdoorparadise].[dbo].[Employee] AS m
    ON e.Manager_id = m.Emp_id
INNER JOIN
    [outdoorparadise].[dbo].[Employee_staff] AS es
    ON e.Manager_id = es.Emp_staff_code
WHERE e.Emp_id = @Emp_id;

我得到了这个触发器：

CREATE TRIGGER checkSalary ON Employee_staff
AFTER UPDATE
AS
    DECLARE
    @Emp_id INT,
    @NewSalary MONEY,
    @ManagerSalary MONEY;

    SELECT @NewSalary = Salary
    FROM inserted;

    SELECT @Emp_id = Emp_staff_code
    FROM inserted;

    EXEC getManagerSalary @Emp_id = @Emp_id, 
        @ManagerSalary = @ManagerSalary OUTPUT;

    IF @NewSalary > @ManagerSalary
        BEGIN
        RAISERROR 60000 'Salary cannot be higher than the salary of the manager!'
        ROLLBACK TRANSACTION;
        END
    ELSE
        COMMIT TRANSACTION;

当我将薪水更新为高于经理薪水的值时，我得到加薪错误+此错误：交易在触发器中结束。批次已中止。

当我尝试将薪水更新为低于经理薪水的价值时，我仍然得到：交易在触发器中结束。批次已中止。

有人可以告诉我如何解决这个问题？我搜索过，但找不到任何东西。

谢谢， Ryuken

PS：这是我的第一篇文章，也许我没有用正确的方式粘贴代码，所以很抱歉。

抛弃扳机。用检查约束和标量函数替换它。

CREATE FUNCTION dbo.GetManagerSalary(@Emp_id int) RETURNS money
AS
BEGIN
    RETURN
        SELECT es.Salary
        FROM [dbo].[Employee] e 
        JOIN [dbo].[Employee] m ON m.Emp_id = e.Manager_id
        JOIN [dbo].[Employee_staff] es ON es.Emp_staff_code = e.Manager_id
        WHERE e.Emp_id = @Emp_id;
END

GO

ALTER TABLE Employee_staff
    ADD CONSTRAINT CK_Salary
    CHECK (ISNULL([Salary], 0) <= ISNULL(dbo.GetManagerSalary([Salary]), 1e9)))

SQL Server 2008事务以触发器结束。批次已中止
