在 SQL Server 中按月排序

Question

; WITH DS AS
(
    SELECT CAST(DATEADD(YEAR, -25, GETDATE()) AS DATE) AS [Date]

    UNION ALL

    SELECT DATEADD(Month, 1, [Date])
    FROM DS
    WHERE Date < GETDATE()-1
)
SELECT
    [EI].[FirstName] + ' ' + [EI].[LastName] AS [EmployeeName], 
    [EI].[DOJ], 
    DATENAME(MONTH, DS.[Date]) AS [Month], 
    ISNULL(HIS.Salary, [EI].Salary) AS Salary
FROM 
    [HRM].[tbl_Designation] [Desig], [HRM].[tbl_Department] [Dpt], [HRM].[tbl_EmployeeInfo] [EI]
INNER JOIN 
    DS ON [EI].[DOJ] <= DS.[Date]  
LEFT JOIN 
    HRM.tbl_EmployeeInfoHistory as HIS ON HIS.EmpCode = [EI].ID AND HIS.DOJ <= DS.[Date]  
WHERE 
    [Dpt].[ID] = [EI].[DeptCode] 
    AND [Desig].[ID] = [EI].[DesignationCode]
    AND YEAR(DS.[Date]) = '2016'
ORDER BY 
    DATEPART(MM, DATENAME(MONTH, DS.[Date]))
OPTION(MaxRecursion 10000)

我创建了这个查询，其中显示了每个员工的月薪以及月份名称。我无法按 1 月、2 月、3 月、...等相应的顺序对月份进行排序。

我得到的是这样的：

Muhammad Irfan  2012-02-12      May         25000.00
Muhammad Irfan  2012-02-12      April       25000.00
Muhammad Irfan  2012-02-12      January     25000.00
Muhammad Irfan  2012-02-12      March       25000.00 
Muhammad Irfan  2012-02-12      February    25000.00
Muhammad Irfan  2012-02-12      September   25000.00
Muhammad Irfan  2012-02-12      August      25000.00

谁能帮我弄清楚如何以正确的方式对月份进行排序？

另外，YEAR(DS.[Date]) = '2016' 只接受整数输入，但是当我传递任何日期时，它会抛出异常。我尝试将日期转换为整数，但尽管存在记录，但没有给出任何结果。也许有人可以帮助我。

谢谢

代替

ORDER BY datepart(MM,DateName(month, DS.[Date]))

随便用

ORDER BY datepart(MM,DS.[Date])

或者

ORDER BY  MONTH(DS.[Date])
