Question

这是迄今为止的情景。我应该在公司中显示第四名（仅限第四名，而不是前四名）有偿人员。但是我不想使用子查询。那就是问题所在。我似乎无法找到一种只显示第四种方式的方法。

这是我目前的代码

SELECT TOP 5 E1.BusinessEntityID, SUM(E2.PayFrequency*E2.Rate) AS Pay
FROM HumanResources.EmployeePayHistory AS E1
INNER JOIN HumanResources.EmployeePayHistory AS E2
ON E1.BusinessEntityID=E2.BusinessEntityID
GROUP BY E1.BusinessEntityID
ORDER BY SUM(E2.PayFrequency*E2.Rate) DESC

提前谢谢

Answer 1

OFFSET/FETCH可以轻松完成此操作：

SELECT TOP 5 E1.BusinessEntityID, SUM(E2.PayFrequency*E2.Rate) AS Pay
FROM HumanResources.EmployeePayHistory AS E1
INNER JOIN HumanResources.EmployeePayHistory AS E2
   ON E1.BusinessEntityID=E2.BusinessEntityID
GROUP BY E1.BusinessEntityID
ORDER BY SUM(E2.PayFrequency*E2.Rate) DESC
OFFSET 3 ROWS FETCH NEXT 1 ROWS ONLY;

Answer 2

您也可以使用行号

执行此操作

with cte
as
(
SELECT TOP 5 E1.BusinessEntityID, SUM(E2.PayFrequency*E2.Rate) AS Pay,row_number() over (ORDER BY SUM(E2.PayFrequency*E2.Rate) DESC) as rn
FROM HumanResources.EmployeePayHistory AS E1
INNER JOIN HumanResources.EmployeePayHistory AS E2
ON E1.BusinessEntityID=E2.BusinessEntityID
GROUP BY E1.BusinessEntityID
ORDER BY SUM(E2.PayFrequency*E2.Rate) DESC
)
select * from cte where rn=4

在这种情况下是否可以显示我想要的特定行？
