在用到mysql update in的时候报错
update area set status='ON' where id in(select id from area where status='ON' and name like '%市辖%')
[SQL]update area set status='ON' where id in(select id from area where status='ON' and name like '%市辖%')
[Err] 1093 - You can't specify target table 'area' for update in FROM clause
下面语句可以通过
update area a inner join(select id from area where id in(select id from area where status='ON' and name like '%市辖%')) b on a.id=b.id set a.status='OFF' select * from area a inner join(select id from area where id in(select id from area where status='ON' and name like '%市辖%')) b on a.id=b.id
