MYSQL #1093 - You can't specify target table 'dealer_admin' for update in FROM clause

update dealer_admin set is_super_admin=1 where id in (select id from dealer_admin group by dealer_id );
此时会报:#1093 - You can't specify target table 'dealer_admin' for update in FROM clause
在网上找了一个暂时可以解决的方法
create temporary table tmp (id int);
insert into tmp (id) select id from dealer_admin group by dealer_id;
update dealer_admin set is_super_admin=1 where id in (select id from tmp);
