限制SQL查詢

Question

如何在下列查詢中將結果限制爲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

的answer by kevingessner肯定是最簡單的方法。

我只是覺得我會拋出一些替代品的樂趣。

SET ROWCOUNT 10 

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

SET ROWCOUNT 0 

還是比較令人費解的方式：

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
