MySQL查询创建用户并授予权限

要创建用户并授予许可，语法如下：

create database yourDatabaseName DEFAULT CHARACTER SET utf8;

create user `yourUserName` identified by yourPassword;

GRANT SELECT ON yourDatabaseName .* TO `yourUserName`;

GRANT INSERT ON yourDatabaseName .* TO `yourUserName`;

GRANT UPDATE ON yourDatabaseName .* TO `yourUserName`;

GRANT DELETE ON yourDatabaseName .* TO `yourUserName`;

GRANT EXECUTE ON yourDatabaseName .* TO `yourUserName`;

这是创建用户并授予权限的查询-

create database demo_app DEFAULT CHARACTER SET utf8;

create user `John_123` identified by '123456';

GRANT SELECT ON demo.* TO `John_123`;

GRANT INSERT ON demo.* TO `John_123`;

GRANT UPDATE ON demo.* TO `John_123`;

GRANT DELETE ON demo.* TO `John_123`;

GRANT EXECUTE ON demo.* TO `John_123`;

让我们显示上述用户的所有授权：

show grants for `John_123`;

这将产生以下输出-

+-----------------------------------------------------------------------------+

| Grants for John_123@% |

+-----------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO `John_123`@`%` |

| GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON `demo`.* TO `John_123`@`%` |

+-----------------------------------------------------------------------------+
