在Mysql下执行删除重复记录的SQL语句: delete from blur_article where id not in(select min(id) from blur_article group by title)执行后报错! #1093 - You can't specify target table 'blur_article' for update in FROM clause 在Mysql下执行查询: select * from blur_article where id not in(select min(id) from blur_article group by title) 执行语句显示成功!上面的delete却不能执行,此时的去重复操作在mysql中不能这么用。 (等待mysql升级后也许可以) 错误提示就是说,不能先select出同一表中的某些值,再update这个表(在同一语句中) 可以尝试以下替换方案去重复: create table tmp as select min(id) as col1 from blur_article group by title; delete from blur_article where id not in (select col1 from tmp); drop table tmp;
