phpmyadmin
bitsCN.comphpMyAdmin是一款不错的管理mysql的web系统,利用phpMyAdmin创建数据库,创建用户,设置用户权限,备份数据,恢复数据都很方便。
在管理数据库方面,安全非常重要,最小的的权限,最大的安全。下面讲下如何通过phpMyAdmin来设置不同数据库的访问用户权限。
第一步:管理员权限账号登陆phpMyAdmin,一般用root登录
第二部:创建要设置权限的数据库(如果已经存在就不需要了)
填好数据库名称,数据库编码,我选择的是“中文-Chinese simplified”编码,点击创建,数据看就建好了
第三步:创建管理用户
创建完数据库后,点击新数据库sweiku.com,点击权限,出现一个新界面,再点击添加新用户,如上图
在这一步,特别注意,全局权限不需要选择,然后直接点执行。
第四步:设置用户权限
选择相应的权限,点击执行
上面权限意思可以对照下面翻译:
数据:
SELECT:允许读取数据。
INSERT:允许插入和替换数据。
UPDATA:允许更改数据。
DELETE:允许删除数据。
FILE:允许从文件中导入数据以及将数据导出至文件。
结构:
CREATE:允许创建新数据库和表。
ALTER:允许修改现有表的结构。
INDEX:允许创建和删除索引。
DROP:允许删除数据库和表。
CREATE TEMPORARY TABLES:允许创建暂时表。
CREATE VIEW:允许创建新的意见。
SHOW VIEW:显示创建的看法。
CREATE ROUTINE:允许创建存储过程。
ALTER ROUTINE:允许改变和下降存储过程。
EXECUTE:允许许执行存储过程。
管理:
GRANT:允许添加用户和权限,而不允许重新载入权限表。
SUPER:允许在达到最大允许数目时仍进行连接。
PROCESS:允许查看进程列表中的完整查询。
RELOAD:允许重新载入服务器设置并刷新服务器的缓存。
SHUTDOWN:允许关闭服务器。
SHOW DATABASES:允许访问完整的数据库列表。
LOCK TABLES:允许锁住当前线索的表。
REFERENCES:在此版本的 MySQL 中无效。
REPLICATION CLIENT:用户有权询问附属者/控制者在哪里。
REPLICATION SLAVE:回复附属者所需。
CREATE USER:允许创建,下降和重新命名的用户帐户。
至此,数据库的创建和权限设置就完成了,最后我们可以用新用户登陆phpMyAdmin
我们可以看到,用户可以关了相应权限的数据库,而其他数据库都不可见

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u

Analysis of the basic principles of the MySQL database management system MySQL is a commonly used relational database management system that uses structured query language (SQL) for data storage and management. This article will introduce the basic principles of the MySQL database management system, including database creation, data table design, data addition, deletion, modification, and other operations, and provide specific code examples. 1. Database Creation In MySQL, you first need to create a database instance to store data. The following code can create a file named "my
