MySQL OUTER JOIN語法錯誤

Question

也許facepalm爲你們，但作爲SQL查詢noob我有一個語法問題，任何人都知道什麼是錯的？

SELECT * FROM company C 
OUTER JOIN company_address A ON C.company_id = A.company_id 
WHERE A.company_id IS NULL 

給錯誤：

#1064 - You have an error in your SQL syntax; check the manual that corresponds 
to your MySQL server version for the right syntax to use near 
'OUTER JOIN company_address A ON C.company_id = A.company_id WHERE A.address_id 
' at line 2 

我千恩萬謝審查我的小問題:)

Answer 1

In MySQL你應該使用LEFT OUTER JOIN或RIGHT外部連接。沒有隻是外部連接。如果你需要MySql中的FULL OUTER JOIN you can use UNION of LEFT JOIN and RIGHT JOIN

Answer 2

嘗試

SELECT * FROM company C 
LEFT JOIN company_address A ON C.company_id = A.company_id 
WHERE A.company_id IS NULL
