sql - 限制 SQL 查询

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

利用

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

Answer 3

kevingessner的答案当然是最简单的方法。

我只是想我会为了好玩而扔一些替代品。

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
