修改Mysql procedure,function and view definer

1 一次性修改遇到错误

update mysql.proc set definer='root@%'; 

update mysql.proc set definer='root@%'; ERROR 1054 (42S22): Unknown column 'ERROR (RDS): CANNOT MODIFY RDSDMIN OBJECT' in 'field list'

2 缩写修改的范围

update mysql.proc set definer='root@%' where Name='my_proc';
