update の時同じテーブルに対するサブクエリからの操作ができない
update hoge set code = 0 where id IN (select id from hoge as tmp where id = 1 group by id order by id) ; ERROR 1093 (HY000): You can't specify target table 'hoge' for update in FROM clause

update hoge set code = 0 where id IN ( select id from (select id from hoge where id = 1 group by id order by id) as tmp ) ;
