MySQL is a popular relational database management system used by many websites and applications to store and retrieve data. For beginners, the installation and use of MySQL can be a bit difficult, especially if you don't understand how to enter MySQL. This article will introduce how to enter MySQL.
1. Install MySQL
First, we need to install MySQL on the computer. You can download the MySQL installation program suitable for your operating system from the MySQL official website. The installer will guide you through the MySQL installation process.
After the installation is complete, the MySQL server should have started. You can view the running status of the MySQL process in Task Manager or System Monitor.
2. Use the command line tool to enter MySQL
MySQL provides a command line tool called the MySQL client. Through this tool, we can enter the server and interact with the MySQL database. Here are the basic steps to enter the MySQL server:
- Open a command prompt (Windows) or terminal (Mac, Linux).
-
Enter the following command to enter MySQL:
mysql -u username -p
Among them,
username
is MySQL A registered user account in . If you have just installed MySQL, you can useroot
as the username. After entering it, MySQL will prompt you for the password of the corresponding user. If the password is correct, you have now successfully entered the MySQL server.Note: No characters will be displayed when entering the password. This is for security reasons to protect the password from being seen by others.
-
Next, enter the SQL query at the MySQL prompt.
For example, the following query will display all currently existing MySQL databases:
SHOW DATABASES;
After executing the query, MySQL will return one or more A list of database names.
3. Use GUI tools to enter MySQL
The command line tool is the standard tool for MySQL, but there are some third-party GUI tools that can make MySQL interaction more intuitive and easier use. These tools provide a visual interface, simplifying the process of connecting and operating the database, and are especially suitable for beginners. The following are some commonly used MySQL GUI tools:
- MySQL Workbench: MySQL's official GUI tool. It can provide functions for transformation, modeling and database management.
- phpMyAdmin: A web-based GUI tool. You can connect to the MySQL server through the browser and operate databases and tables.
- Navicat for MySQL: A popular commercial GUI tool that supports multiple operating systems, including Windows, Mac, Linux, iOS, etc.
The method of entering MySQL through these GUI tools may vary depending on the tool you use. However, you usually need to provide the following information to connect to the MySQL server:
- Host name and port number: The IP address and port number of the MySQL server. The default port number is 3306.
- Username and Password: Credentials of the registered MySQL user account.
- Database name (some tools can skip this step because the database can be created later).
After configuring this information, you can connect to the MySQL server by clicking the "Connect" button or entering specific commands.
4. Summary
MySQL is a powerful relational database management system with many suppliers and wide applications. In order to use MySQL, we first need to install it. To use the command line tool to enter the MySQL server, you need to provide a user name and password, and to use the GUI tool, you need to provide the IP address, port number, user name, password and other information of the MySQL server. Although the command line tool may be more convenient for experienced MySQL users, the visual operation interface provided by the GUI tool is more friendly and easier for beginners to get started. I hope this article can help readers get into MySQL more easily and start using it.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

MySQL/InnoDB supports four transaction isolation levels: ReadUncommitted, ReadCommitted, RepeatableRead and Serializable. 1.ReadUncommitted allows reading of uncommitted data, which may cause dirty reading. 2. ReadCommitted avoids dirty reading, but non-repeatable reading may occur. 3.RepeatableRead is the default level, avoiding dirty reading and non-repeatable reading, but phantom reading may occur. 4. Serializable avoids all concurrency problems but reduces concurrency. Choosing the appropriate isolation level requires balancing data consistency and performance requirements.

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.
