delete from sinykk_love_web where id in (select id from sinykk_love_web group by site_url having count(site_url)>1)


1093 - You can't specify target table 'sinykk_love_web' for update in FROM clause


改成如下就好


delete from sinykk_love_web where id in (select temp.id from (select m. id,m.site_url from sinykk_love_web m)? temp group by temp.site_url having count(temp.site_url)>1)
