mysql权限分为全局权限、库权限、表权限，对应于mysql库里面的user表、db表、tables_priv表。mysql

grant all privileges on *.* :操做mysql.user表
sql

grant all privileges on db.* :操做mysql.db表ide

grant all privileges on db.table :操做mysql.tables_priv表spa

这三种操做分别对应不一样的表，互不影响，赋予一个用户大粒度的权限，并不能收回小粒度的权限。it

示例以下：table

root@localhost:mysql3306.sock 14:02: [test]>grant all privileges on *.* to test@'127.0.0.1'; class

Query OK, 0 rows affected (0.00 sec)test

root@localhost:mysql3306.sock 14:03: [test]>revoke update on test.* from test@'127.0.0.1'; date

ERROR 1141 (42000): There is no such grant defined for user 'test' on host '127.0.0.1'权限

root@localhost:mysql3306.sock 14:03: [test]>revoke update on test.a from test@'127.0.0.1';

ERROR 1147 (42000): There is no such grant defined for user 'test' on host '127.0.0.1' on table 'a'
