MySQL更新查询不起作用＃1064

Question

有人能告诉我这个查询有什么问题吗？

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

此代码示例适用于我的数据库：

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

请改为尝试：

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