如何使用MySQL授予对服务器上所有数据库中所有表的所有表的SELECT？
为此，您可以按照以下语法使用GRANTSELECT语句-
GRANT SELECT ON *.* TO 'yourUserName'@'yourHostName';
首先列出所有用户名以及主机-
select user,host from mysql.user;
这将产生以下输出-
+------------------+-----------+ | user | host | +------------------+-----------+ | Bob | % | | Charlie | % | | Robert | % | | User2 | % | | mysql.infoschema | % | | mysql.session | % | | mysql.sys | % | | root | % | | @UserName@ | localhost | | Adam | localhost | | Adam Smith | localhost | | Chris | localhost | | David | localhost | | Emma | localhost | | Jace | localhost | | James | localhost | | John | localhost | | John Doe | localhost | | Michael | localhost | | Mike | localhost | | Robert | localhost | | User1 | localhost | | am | localhost | | hbstudent | localhost | | mysql.infoschema | localhost | | mysql.session | localhost | +------------------+-----------+ 26 rows in set (0.00 sec)
这是实现GRANTSELECT的查询-
GRANT SELECT ON *.* TO 'hbstudent'@'localhost';
