INNER JOIN作品SELECT但不是DELETE

Question

爲什麼這個有語法錯誤

DELETE FROM `print_mailing_request` pmr 
INNER JOIN `person` p 
    ON p.id = pmr.person AND p.email LIKE '%@TEST.COM' 
WHERE 
pmr.sent_to_fulfiller != 'y' 

當這正常工作沒有錯誤？

SELECT * FROM `print_mailing_request` pmr 
INNER JOIN `person` p 
    ON p.id = pmr.person AND p.email LIKE '%@TEST.COM' 
WHERE 
pmr.sent_to_fulfiller != 'y' 

Answer 1

正確的語法如下所示，而不使用表別名。您缺少要從中刪除的表名。

DELETE `print_mailing_request` 
FROM `print_mailing_request` 
INNER JOIN `person` 
    ON `person`.id = `print_mailing_request`.person 
    AND `person`.email LIKE '%@TEST.COM' 
WHERE `print_mailing_request`.sent_to_fulfiller != 'y' 

Answer 2

你需要告訴delete什麼表中進行刪除：

DELETE pmr 
    FROM `print_mailing_request` pmr INNER JOIN 
     `person` p 
     ON p.id = pmr.person AND p.email LIKE '%TEST.COM' 
    WHERE pmr.sent_to_fulfiller != 'y'; 

表的別名那張delete一句之後，from之前。我假設它是提到的第一張桌子。
