MySQL stores name data types: 1) VARCHAR(n): variable-length characters, up to n characters, suitable for names with variable length; 2) CHAR(n): fixed-length characters, always stores n Characters, suitable for names with fixed length; 3) TEXT: variable-length text, which can store very long names or special characters; 4) BLOB: binary large objects, not suitable for storing names.
Name data type in MySQL
Name is a common attribute data type in the database. In MySQL, depending on the storage and processing requirements of the name, the following data types can be used:
VARCHAR(n)
- Variable length character type
- Allows storage of up to n characters
- The value of n must be between 1 and 65535
- It is suitable for storing names of up to n characters, and is more efficient when storing names with variable length. High
CHAR(n)
- Fixed-length character type
- Always stores n characters
- The value of n must be between 1 and 255
- Suitable for storing fixed-length and immutable names, it is more efficient when processing fixed-length names
TEXT
- Variable length text type
- Allows storage of very long text (up to 65535 bytes)
- Suitable for storing very long names or names with Names with special characters require more storage space
BLOB
- Binary large object type
- Allows the storage of binary data (includes image, audio, or video files)
- Not suitable for storing names because names are usually text-based
Generally, using VARCHAR(n) is the best choice for storing names , because it is both flexible and efficient. If the name is of fixed and immutable length, CHAR(n) is a more appropriate option. For very long names or names with special characters, the TEXT or BLOB types provide greater storage capacity.

Best practices to prevent SQL injection include: 1) using parameterized queries, 2) input validation, 3) minimum permission principle, and 4) using ORM framework. Through these methods, the database can be effectively protected from SQL injection and other security threats.

MySQL is popular because of its excellent performance and ease of use and maintenance. 1. Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2. Insert and query data: operate data through INSERTINTO and SELECT statements. 3. Optimize query: Use indexes and EXPLAIN statements to improve performance.

The difference and connection between SQL and MySQL are as follows: 1.SQL is a standard language used to manage relational databases, and MySQL is a database management system based on SQL. 2.SQL provides basic CRUD operations, and MySQL adds stored procedures, triggers and other functions on this basis. 3. SQL syntax standardization, MySQL has been improved in some places, such as LIMIT used to limit the number of returned rows. 4. In the usage example, the query syntax of SQL and MySQL is slightly different, and the JOIN and GROUPBY of MySQL are more intuitive. 5. Common errors include syntax errors and performance issues. MySQL's EXPLAIN command can be used for debugging and optimizing queries.

The diversity and power of SQL make it a powerful tool for data processing. 1. The basic usage of SQL includes data query, insertion, update and deletion. 2. Advanced usage covers multi-table joins, subqueries, and window functions. 3. Common errors include syntax, logic and performance issues, which can be debugged by gradually simplifying queries and using EXPLAIN commands. 4. Performance optimization tips include using indexes, avoiding SELECT* and optimizing JOIN operations.

The core role of SQL in data analysis is to extract valuable information from the database through query statements. 1) Basic usage: Use GROUPBY and SUM functions to calculate the total order amount for each customer. 2) Advanced usage: Use CTE and subqueries to find the product with the highest sales per month. 3) Common errors: syntax errors, logic errors and performance problems. 4) Performance optimization: Use indexes, avoid SELECT* and optimize JOIN operations. Through these tips and practices, SQL can help us extract insights from our data and ensure queries are efficient and easy to maintain.

The role of SQL in database management includes data definition, operation, control, backup and recovery, performance optimization, and data integrity and consistency. 1) DDL is used to define and manage database structures; 2) DML is used to operate data; 3) DCL is used to manage access rights; 4) SQL can be used for database backup and recovery; 5) SQL plays a key role in performance optimization; 6) SQL ensures data integrity and consistency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
