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%'
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
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
