SQL joins for Beginners | Right join | Left Join | Cross Join | Inner Join | SQL

In this comprehensive SQL tutorial, we explore the different types of SQL joins using practical examples: LEFT JOIN, RIGHT JOIN, CROSS JOIN, and INNER JOIN. Understanding how to join tables is a crucial skill for any SQL developer, and we will break down each join type with easy-to-follow queries and outputs using Table1 and Table3. What You’ll Learn: LEFT JOIN: Learn how to retrieve all rows from the left table (Table1) and matching rows from the right table (Table3). Non-matching rows from the right table will be returned as NULL. RIGHT JOIN: Understand how RIGHT JOIN returns all rows from the right table (Table3) and matching rows from the left table (Table1). Non-matching rows from the left table are returned as NULL. CROSS JOIN: Discover how the CROSS JOIN combines every row from Table1 with every row from Table3 to produce the Cartesian product. INNER JOIN: See how INNER JOIN returns only the rows with matching values from both tables. Example: We’ll work with two sample tables: Table1 with data: 1, 1, 1, 2, 2, 3, 5 Table3 with data: 1, 1, 2, 3, 4 Learn how these joins impact the resulting output, and understand when to use each join type for different data retrieval needs. 👉 Don't forget to like, comment, and subscribe for more SQL tutorials! 🔔 Stay tuned for more database and SQL learning content!
