MySQL数据库已经应用到很多互联网公司,mysql权限管理非常重要,合理规划好mysql数据库权限,对数据库的安全和使用是非常有好处的.一个好的规范和习惯,做任何事也不会出现大问题.
下面是mysql权限规划授权的语句:
授权jc用户,查询、插入、更新、删除 本机testdb数据库中所有表数据的权利的授权方法如下:
grant select on testdb.* to jc@’localhost’
grant insert on testdb.* to jc@’localhost’
grant update on testdb.* to jc@’localhost’
grant delete on testdb.* to jc@’localhost’
授权jc用户,创建、修改、删除 MySQL 数据表结构权限
grant create on testdb.* to jc@’localhost’;
grant alter on testdb.* to jc@’localhost’;
grant drop on testdb.* to jc@’localhost’;
授权jc用户,操作MySQL外键权限
grant references on testdb.* to jc@’localhost’;
授权jc用户操作MySQL临时表权限
grant create temporary tables on testdb.* to jc@'localhost’
授权jc用户操作MySQL索引权限
grant index on testdb.* to jc@'localhost’;
授权jc用户操作MySQL视图,网站空间,查看视图源代码权限
grant create view on testdb.* to jc@’localhost’;
grant show view on testdb.* to jc@’localhost’;
授权jc用户管理某个MySQL数据库的权限:
grant all privileges on testdb to jc@’localhost’;
授权jc用户管理MySQL中所有数据库的权限:
grant all on *.* to jc@’localhost';
授权jc用户权限分别可以作用在多个层次上。
1. grant 作用在整个 MySQL 服务器上:
grant select on *.* to jc@localhost; — jc可以查询 MySQL 中所有数据库中的表。
grant all on *.* to jc@localhost; — jc可以管理 MySQL 中的所有数据库
2. grant 作用在单个数据库上:
grant select on testdb.* to jc@localhost; — jc可以查询 testdb 中的表。
3. grant 作用在单个数据表上:
grant select, insert, update, delete on testdb.orders to jc@localhost;
4. grant 作用在表中的列上:
grant select(id, se, rank) on testdb.apache_log to jc@localhost;
5. grant 作用在存储过程、函数上:
grant execute on procedure testdb.pr_add to ‘jc’@'localhost’
grant execute on function testdb.fn_add to ‘jc’@'localhost’
查看 MySQL 用户权限
查看当前用户(自己)权限:
show grants;
查看其他 MySQL 用户权限:
show grants for dba@localhost;
撤销已经赋予给 MySQL 用户权限的权限。
revoke 跟 grant 的语法差不多,只需要把关键字 “to” 换成 “from” 即可:
grant all on *.* to jc@localhost;
revoke all on *.* from jc@localhost;
权限授权语法和列表:
GRANT 语法:
GRANT privileges (columns)
ON what
TO user IDENTIFIED BY "password"
WITH GRANT OPTION

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
