Answer 1

运行以下查询的输出：

SELECT CONCAT("GRANT SELECT ON ",SCHEMA_NAME,".* TO 'test_user'@'localhost';")
FROM information_schema.SCHEMATA 
WHERE SCHEMA_NAME NOT LIKE 'mysql';

Answer 2

既然你有200个数据库，又不想一一授予。最快的方法是

GRANT SELECT ON *.* TO 'test_user'@'localhost';
FLUSH PRIVILEGES;

然后只需撤销mysql db中的权限

REVOKE SELECT ON mysql.* FROM 'test_user'@'localhost' ;
FLUSH PRIVILEGES;

但是当我有选择地 GRANT 然后 REVOKE 在 mysql.* 上。然后它正在工作
