MYSQL到MSSQL UPDATION：

update products set Stock=A.Stock from
(Select * FROM OPENQUERY(MYSQL,'Select * From products')) A
inner join products B on b.Id=a.Id



UPDATE employee
SET LastName = ( Select FirstName from employee where FirstName = (SELECT * FROM
OPENQUERY(MYSQL, 'Select FirstName from employee where IndividualId=3')))

MSSQL到MYSQL更新：

UPDATE OPENQUERY (database, 'SELECT Stock FROM wings.products WHERE id =1') 
SET Stock=999;

我需要在LINKED服务器中从Mssql到Mysql的更新查询
