mysql如何仅保留最新10条数据而删除其他记录

如果想准确控制最多不会超过10条，应该只能用触发器如果定时清理，假设是按照主键排序，并且主键是自增先查出最新第10个主键ID，然后再删除主键小于"第10个主键ID"的所有记录DELETE tb FROM tb_name AS tb ,(SELECT pk_id FROM tb_name ORDER BY pk_id desc LIMIT 9,1) AS tmpWHERE tb.pk_id<tmp.pk_id

delete from `mygame_article` where title in (select title from `mygame_article` group by id having count(title) >1) and id not in (select max(id) from `mygame_article` group by title having count(title) >1)

随手写了个，前半句是选择title重复的数据，后半句是剔除id最大的，delete是删除的意思。。应该 思路是没问题的，这边不方便帮您测试
