MYSQL批量插入如果存在

Question

我在寻找的东西similar-

insert into table1(a, b, c) 
select col1 as d, col2 as e, col3 as f from table2 
on duplicate key update b = e, c = f; 

注意：如果不存在更新。

我收到错误 - 未知的列名'e'。

是否有任何解决方案使用'重复键'与'插入选择'语句？

谢谢！

迷惑造成使用别名

insert into table1(a, b, c) 
select col1 as d, col2 as e, col3 as f from table2 
on duplicate key update b = table2.col2, c = table2.col3;
