Question

我试图显示别名 [totalmonthly] 的最大值，我试图输入 {SUM(([Price]-[CostToMake])* MonthlySales)} 但仍然没有显示。我在这里做错了什么？

SELECT      Name, 
            SUM(([Price]-[CostToMake])* MonthlySales) AS TotalMonthly
FROM        SalesTable
GROUP BY    Name
HAVING      MAX(TotalMonthly)

我收到错误消息：

Msg 4145, Level 15,
An expression of non-boolean type specified in a context where a condition is expected, near ')'

Answer 1

使用TOP (1)和ORDER BY:

SELECT TOP (1) Name, 
       SUM(([Price]-[CostToMake])* MonthlySales) AS TotalMonthly
FROM SalesTable
GROUP BY Name
ORDER BY TotalMonthly DESC;

我假设您的查询产生了错误，而不是错误的结果。
