Usage of like in sql:
The operator LIKE uses wildcards to compare a value with similar values. There are two wildcards:
1. Percent sign (%): represents zero, one or more characters
2. Underscore (_): represents a number or character
The condition matches any value that starts with 200
WHERE SALARY LIKE '200%'
The following condition matches any value that contains 200 (at any position)
WHERE SALARY LIKE '%200%'
The following condition matches the second and third characters that are 0 Value
WHERE SALARY LIKE '_00%'
The following condition matches values that start with 2 and have a length of at least 3
WHERE SALARY LIKE '2_%_%'
The following condition matches values whose second position is 2 and ends with 3
WHERE SALARY LIKE '_2%3'

The Importance of SQL: Data Management in the Digital AgeApr 23, 2025 am 12:01 AMSQL's role in data management is to efficiently process and analyze data through query, insert, update and delete operations. 1.SQL is a declarative language that allows users to talk to databases in a structured way. 2. Usage examples include basic SELECT queries and advanced JOIN operations. 3. Common errors such as forgetting the WHERE clause or misusing JOIN, you can debug through the EXPLAIN command. 4. Performance optimization involves the use of indexes and following best practices such as code readability and maintainability.
Getting Started with SQL: Essential Concepts and SkillsApr 22, 2025 am 12:01 AMSQL is a language used to manage and operate relational databases. 1. Create a table: Use CREATETABLE statements, such as CREATETABLEusers(idINTPRIMARYKEY, nameVARCHAR(100), emailVARCHAR(100)); 2. Insert, update, and delete data: Use INSERTINTO, UPDATE, DELETE statements, such as INSERTINTOusers(id, name, email)VALUES(1,'JohnDoe','john@example.com'); 3. Query data: Use SELECT statements, such as SELEC
SQL: The Language, MySQL: The Database Management SystemApr 21, 2025 am 12:05 AMThe relationship between SQL and MySQL is: SQL is a language used to manage and operate databases, while MySQL is a database management system that supports SQL. 1.SQL allows CRUD operations and advanced queries of data. 2.MySQL provides indexing, transactions and locking mechanisms to improve performance and security. 3. Optimizing MySQL performance requires attention to query optimization, database design and monitoring and maintenance.
What SQL Does: Managing and Manipulating DataApr 20, 2025 am 12:02 AMSQL is used for database management and data operations, and its core functions include CRUD operations, complex queries and optimization strategies. 1) CRUD operation: Use INSERTINTO to create data, SELECT reads data, UPDATE updates data, and DELETE deletes data. 2) Complex query: Process complex data through GROUPBY and HAVING clauses. 3) Optimization strategy: Use indexes, avoid full table scanning, optimize JOIN operations and paging queries to improve performance.
SQL: A Beginner-Friendly Approach to Data Management?Apr 19, 2025 am 12:12 AMSQL is suitable for beginners because it is simple in syntax, powerful in function, and widely used in database systems. 1.SQL is used to manage relational databases and organize data through tables. 2. Basic operations include creating, inserting, querying, updating and deleting data. 3. Advanced usage such as JOIN, subquery and window functions enhance data analysis capabilities. 4. Common errors include syntax, logic and performance issues, which can be solved through inspection and optimization. 5. Performance optimization suggestions include using indexes, avoiding SELECT*, using EXPLAIN to analyze queries, normalizing databases, and improving code readability.
SQL in Action: Real-World Examples and Use CasesApr 18, 2025 am 12:13 AMIn practical applications, SQL is mainly used for data query and analysis, data integration and reporting, data cleaning and preprocessing, advanced usage and optimization, as well as handling complex queries and avoiding common errors. 1) Data query and analysis can be used to find the most sales product; 2) Data integration and reporting generate customer purchase reports through JOIN operations; 3) Data cleaning and preprocessing can delete abnormal age records; 4) Advanced usage and optimization include using window functions and creating indexes; 5) CTE and JOIN can be used to handle complex queries to avoid common errors such as SQL injection.
SQL and MySQL: Understanding the Core DifferencesApr 17, 2025 am 12:03 AMSQL is a standard language for managing relational databases, while MySQL is a specific database management system. SQL provides a unified syntax and is suitable for a variety of databases; MySQL is lightweight and open source, with stable performance but has bottlenecks in big data processing.
SQL: The Learning Curve for BeginnersApr 16, 2025 am 12:11 AMThe SQL learning curve is steep, but it can be mastered through practice and understanding the core concepts. 1. Basic operations include SELECT, INSERT, UPDATE, DELETE. 2. Query execution is divided into three steps: analysis, optimization and execution. 3. Basic usage is such as querying employee information, and advanced usage is such as using JOIN connection table. 4. Common errors include not using alias and SQL injection, and parameterized query is required to prevent it. 5. Performance optimization is achieved by selecting necessary columns and maintaining code readability.

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),
