Error Code: 1093. You can't specify target table 'recharge_log' for update in FROM clause解决

 

You can't specify target table 'recharge_log' for update in FROM clause

 

这个问题出现的情况是:

 

更新一个表的数据时，where条件中包含被表新表的子查询：

delete from r_log where ope = "111" and site in (select distinct(site) from r_log where operators = "1111uu");

 

 

我的解决办法是把子查询的结果放到一个临时表，然后再进行删除或更新操作，问题完美解决。

 

drop table dist_site;create TEMPORARY table dist_site select distinct(site) from r_log where operators = "1111uu";select * from r_log where operators = "111"
 and site in (select * from dist_site);
