Question

我们说我有这个SP：

ALTER PROCEDURE [dbo].[testsp]
    -- Add the parameters for the stored procedure here
    @start datetime,
    @end datetime,
    @sort int = 1
AS
BEGIN
    set nocount on;
    select
        t1.Name,
        sum(t2.sum) as Salary
    from
        persons t1 inner join
        payments t2 on(t1.ID = t2.PersonID)
    where
        t1.Active = 1 and 
        t2.TimeOfTransfer between @start and @end
    group by 
        t1.Name
    order by 
        [Salary] desc
END

如何编写我的订单，让它根据@sort中的值进行升序或降序排序？

Answer 1

...
ORDER
    BY CASE WHEN @sort = 1 THEN Salary END ASC
     , CASE WHEN @sort = 0 THEN Salary END DESC

P.S。我可能会将您的@sort参数的定义更改为位（仅限值0或1）或 char（4）（对于“ASC”或'DESC'）:-)
