MySQL 8で学ぶSQLデータベース入門:初心者向けマスターガイド

Learn SQL from Scratch: Master Database Fundamentals with MySQL

This comprehensive course guides you from SQL beginner to proficient, using MySQL as the primary database system. While focused on MySQL, the SQL skills you gain are broadly applicable across various Database Management Systems (DBMS). SQL and table design are foundational for any web system development, making this a crucial skill to acquire.

Course Highlights:

• SQL Fundamentals: Sections 2-10 provide a solid foundation in SQL syntax, reinforced with practical exercises to deepen your understanding. You'll master core SQL commands.
• Complex SQL Queries: By completing the course up to the Subquery section (Section 10), you'll gain the ability to construct sophisticated SQL queries.
• Transactions & Data Integrity: Understand transactions, including commit, rollback, and the critical ACID properties that ensure data reliability.
• MySQL 8.x Window Functions: Explore the power of Window Functions, a modern addition to MySQL 8.x, to perform advanced data analysis within queries.
• Database Design & Optimization: Go beyond query writing and learn essential database design principles:
  • Normalization: Understand and apply database normalization techniques.
  • Table Design: Develop effective strategies for designing relational database tables.
  • Data Types: Master various data types (string, numeric, boolean, date & time).
• Performance Tuning: Optimize your SQL queries for speed and efficiency:
  • Index Creation: Learn how to create and utilize indexes for faster data retrieval.
  • Execution Plans: Understand how to interpret execution plans to identify performance bottlenecks.
  • SQL Tuning: Apply techniques to optimize SQL query performance.
  • Index Limitations: Understand the limitations of indexes.
• Advanced SQL Techniques:
  • Stored Procedures: Create Stored Procedures to encapsulate complex logic and perform operations beyond standard SQL capabilities.
  • Subqueries (副問い合わせ): Utilize subqueries to create more complex and powerful queries.
  • WITH (CTE): Leverage Common Table Expressions (CTEs) for cleaner and more readable SQL.
  • Recursive SQL: Work with recursive queries for hierarchical data.
  • IF, CASE Statements: Implement conditional logic within your SQL queries.
  • Window Functions (partition by, order by): Apply window functions with partitioning and ordering for advanced calculations.
  • Constraints: Implement data integrity through primary keys (PK), unique constraints, foreign keys, and check constraints.
• Practical Implementation: The course includes MySQL installation instructions for Windows and Mac, and covers creating databases and tables. You'll learn to perform essential operations like INSERT, SELECT, UPDATE, and DELETE with various clauses (WHERE, AND, OR, LIKE, IN, BETWEEN, etc.). You'll also explore functions for string, numeric, and date manipulation.
• Data Analysis: Learn how to retrieve and analyze statistical information from your database.
