谁能告诉我这个查询有什么问题?
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
