PHP SQL查詢使用陣列

Question

說得這個問題簡單，我用的是follwoing命令：

SELECT DISTINCT a.*, b.shortmessage 
FROM `users` a, `rating` b 
WHERE a.userid IN (333333, 101010) 
    AND b.myuserid IN (333333, 101010) 
    AND b.userid LIKE '000000' 

它返回：

id other_columns shortmessage 
3 Guy1    message from guy1 
9 Guy2    message from guy1 
3 Guy1    message from guy2 
9 Guy2    message from guy2 

注意，我可以使用GROUP BY id，它會顯示2行如預期的那樣，但表2的消息在guy2上將會出錯。

我想要什麼：

id other_columns shortmessage 
3 Guy1    message from guy1 
9 Guy2    message from guy2 

Answer 1

這些項目都是不同的（看每id不同shortmessage）：

id other_columns shortmessage 
3 Guy1    message from guy1 
9 Guy2    message from guy1 
3 Guy1    message from guy2 
9 Guy2    message from guy2

我做了一個快速閱讀了關於INNER從w3s

解決方案：

SELECT * FROM `users` INNER JOIN `rating` ON users.userid=rating.myuserid WHERE users.userid IN (333333, 101010) AND rating.myuserid IN (333333, 101010) AND rating.userid LIKE '000000'
