MYSQL删除重复超过'x'的记录

Question

我试图清理我的WP登录日志并删除从同一个ip进行了超过500次登录尝试的记录。我明白了：

DELETE
FROM wp_simple_login_log
HAVING COUNT(ip) > 500 

但是sql说smth这个陈述错了

Answer 1

你也可以尝试这样的事情：

git push origin HEAD:refs/for/<branch>

Answer 2

试试这个：

DELETE FROM wp_simple_login_log WHERE ip IN 
  (SELECT ip FROM
        (SELECT ip,count(*) as nr FROM wp_simple_login GROUP BY ip) x
  WHERE nr > 500)

我不确定是否有更短或更优雅的解决方案

Answer 3

DELETE FROM wp_simple_login_log 
WHERE ip IN
(
    SELECT * FROM
    (
       SELECT ip
       FROM wp_simple_login_log
       HAVING COUNT(ip) > 500
   ) tmp
);

Answer 4

试试这段代码： 更改您的表ordertable和id是列名

 DELETE FROM ordertable where id IN ( SELECT * FROM (SELECT id FROM
 ordertable group by id having count(id)>1) AS X) ;
