更新内部联接问题

Question

我不知道我的查询有什么问题,但是我收到了这个错误:

Error Code : 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'From a
INNER JOIN table2 b
ON  a.column1 = b.column1 AND a.column2 = b.column2' at line 4

这是我正在尝试的sql:

UPDATE table1 AS a
Set a.Closed = 2

From a
INNER JOIN table2 b
ON  a.column1 = b.column1 AND a.column2 = b.column2
WHERE number in (01809076,02170039);

Answer 1

在MySQL,UPDATEwith join 的语法是这样的.(没有FROM条款)

UPDATE  table1 AS a
        INNER JOIN table2 b
            ON  a.column1 = b.column1 AND 
                a.column2 = b.column2
SET     a.Closed = 2
WHERE   b.number in (01809076,02170039);

你目前正在使用的是 T-SQL
