MySQL更新查詢不起作用＃1064

Question

任何人都可以告訴我這個查詢有什麼問題嗎？

UPDATE 
    violetta.navi__stop 
SET 
    violetta.navi__stop.endHour = VB.endHour 
FROM 
    violetta.navi__stop AS V 
INNER JOIN 
    violetta_back.navi__stop AS VB 
ON V.code = VB.code 

此示例代碼對我的作品在我的數據庫：

SELECT 
V.code, V.endHour 
FROM 
    violetta.navi__stop AS V 
UNIQUE 
    violetta_back.navi__stop AS VB 
ON V.code = VB.code 

Answer 1

試試這個：

UPDATE 
    violetta.navi__stop v 
INNER JOIN 
    violetta_back.navi__stop AS VB 
ON V.code = VB.code 
SET 
    v.endHour = VB.endHour
