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

MySQL中的

，UPDATE加入的语法是这样的。（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);

您当前使用的是T-SQL

Answer 2

请更新您的查询：

更新table1 设置已关闭= 2

来自table1 a INNER JOIN table2 b ON a.column1 = b.column1 AND a.column2 = b.column2 中的数字（01809076,02170039）;

一定会有效

由于 UTTAM

Answer 3

您可以轻松完成：

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