Question

如何在以下查询中将结果限制为10？我使用SQLSRV。

SELECT Id, Firstname, Surname FROM Person WHERE Firstname LIKE ?

Answer 1

使用TOP：

SELECT TOP 10 Id, Firstname, Surname FROM Person WHERE Firstname LIKE ?

Answer 2

使用

select top(10) Id, Firstname, Surname ....

Answer 3

answer by kevingessner肯定是最简单的方式。

我只是觉得我会为了好玩而抛出一些替代品。

SET ROWCOUNT 10

 SELECT Id, Firstname, Surname FROM Person WHERE Firstname LIKE ?

SET ROWCOUNT 0

或者更复杂的方式：

With q 
as 
(
Select ROW_NUMBER() Over(Order by Id) as rn,
        Id,
        Firstname,
        Surname 
FROM Person WHERE Firstname LIKE ?
)
Select * 
From q
where q.rn <= 10

限制SQL查询
