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`@`%` | +-----------------------------------------------------------------------------+ 2 rows in set (0.00 sec)
