ms access 2003中加入的隨機記錄

Question

我想從加入中獲得一個隨機記錄，但是我無法讓它工作！有任何想法嗎？它使用Microsoft Access 2003

table = members 
=============== 
memberID int 
name varchar 

table = testimonials 
==================== 
testimonialID int 
memberID int 
content memo 

select m.*, (SELECT t.content from testimonials t where t.memberID=m.memberID ORDER BY rnd(t.testimonialID)) as testimonialtext 
FROM members m; 

基本上，我需要每個成員的記錄和該成員一個隨機的告別賽。我還要補充一點，我已經試過了內加入太...

select m.*, t.content FROM members m 
INNER JOIN testimonials t ON m.memberID=t.memberID 
ORDER BY rnd(t.testimonialID) 

感謝您的幫助。

Answer 1

嘗試用TOP子句

select m.*, (SELECT top 1 t.content from testimonials t where t.memberID=m.memberID ORDER BY rnd(t.testimonialID)) as testimonialtext 
FROM members m; 

OK限制，那麼我們可以這樣做：

select 
    m.*, 
    t3.content 
FROM 
    members m, 
    (select 
     top 1 t.testimonialID, 
    from 
     testimonials t 
    where 
     t.memberID=m.memberID 
    order by 
     rnd(t.testimonialID) 
    ) t2, 
    testimonials t3 
where 
    t3.testimonialID = t2.testimonialID;
