MYSQL ONDUPLICATE KEY UPDATE ISSUE

我正嘗試使用'ON DUPLICATE KEY UPDATE'語句來更新列時重複的主鍵已在表中。但即使表具有重複主鍵，它也不會更新列。MYSQL ONDUPLICATE KEY UPDATE ISSUE

下面是'ON DUPLICATE KEY UPDATE'語句。有什麼問題嗎？

ON DUPLICATE KEY UPDATE authenticated = authenticated 
        and notAuthenticated = notAuthenticated 
        and stoped = stoped 
        and deleted = deleted 
        and updatedDate = now()

;

使用VALUES(Column)與逗號,取代這一切AND：

ON DUPLICATE KEY UPDATE authenticated = VALUES(authenticated), 
        notAuthenticated = VALUES(notAuthenticated), 
        stoped = VALUES(stoped), 
        deleted = VALUES(deleted), 
        updatedDate = now()

謝謝！它工作正常 – happenask

沒問題的隊友，但我認爲你接受了錯誤的答案@happenask :) – sagi

對不起，我現在修復它 – happenask

不要使用AND，但使用逗號：

ON DUPLICATE KEY UPDATE 
       authenticated = VALUES(authenticated), 
       notAuthenticated = VALUES(notAuthenticated), 
       stoped = VALUES(stoped), 
       deleted = VALUES(deleted), 
       updatedDate = now()
