從隨機選擇中選擇前8行SQLSERVER

Question

我不知道如何從以下查詢中選擇前8行。我對SQL很陌生。

SELECT TOP 100 PERCENT * FROM (
select TEXT, ID, Details 
from tblTEXT 
where (ID = 12 or ID = 13 or ID =15) 

) X 
order by newid() 

此查詢給我31個隨機行，但我想選擇前8

我使用下列但它不工作

select top 8 
from 
(
SELECT TOP 100 PERCENT * FROM (
    select TEXT, ID, Details 
    from tblTEXT 
    where (ID = 12 or ID = 13 or ID =15) 

    ) X 
    order by newid() 
) 

Answer 1

出了什麼問題只是：

SELECT TOP 8 * FROM (
select TEXT, ID, Details 
from tblTEXT 
where (ID = 12 or ID = 13 or ID =15) 

) X 
order by newid() 

（其他的答案是目前不正確，因爲他們不爲外子查詢指定一個名稱，但只有在最外面的查詢的ORDER BY會影響結果訂購無論如何，所以他們有其他的問題，當涉及到可靠性）

Answer 2

試試這個

select top 8 * from 
(
SELECT TOP 100 PERCENT * FROM (
    select TEXT, ID, Details 
    from tblTEXT 
    where (ID = 12 or ID = 13 or ID =15) 

    ) X 
    order by newid() 
)Y 

當然，您從前100行中選擇前8位，您還可以直接從內部查詢中選擇前8位Ÿ通過更換top 100到top 8這樣

SELECT TOP 8 * FROM (
select TEXT, ID, Details 
from tblTEXT 
where (ID = 12 or ID = 13 or ID =15) 

) X 
order by newid() 

Answer 3

你需要指定你想從結果回來什麼： 的*意味着你想看到的everythin。

select top (8) * 
from 
(
SELECT TOP 100 PERCENT * FROM (
    select TEXT, ID, Details 
    from tblTEXT 
    where (ID = 12 or ID = 13 or ID =15) 

    ) X 
    order by newid() 
)
