SQL Joins Explained | INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN, CROSS JOIN, SELF JOIN

In this video, we explore SQL Joins, one of the most important concepts in SQL used to combine data from multiple tables.

Joins allow us to retrieve related data stored across different tables using common columns.

Understanding joins is essential for data analysis, reporting, and real-world database queries.

🔹 SQL Joins covered in this video:

✅ INNER JOIN
Returns only the matching records from both tables.

✅ LEFT JOIN (LEFT OUTER JOIN)
Returns all records from the left table and matching records from the right table.

✅ RIGHT JOIN (RIGHT OUTER JOIN)
Returns all records from the right table and matching records from the left table.

✅ FULL OUTER JOIN
Returns all records from both tables, including matched and unmatched rows.

✅ CROSS JOIN
Returns the Cartesian product of two tables.

✅ SELF JOIN
Joins a table with itself to compare rows within the same table.
