Types of Joins in MySQL

When working with databases, it is essential to understand the different types of joins available in MySQL. Joins are used to retrieve data from multiple tables based on a related column between them. The main types of joins in MySQL are:

1. Inner Join: This type of join returns rows that have matching values in both tables.
2. Left Join (or Left Outer Join): Returns all rows from the left table and matching rows from the right table.
3. Right Join (or Right Outer Join): Returns all rows from the right table and matching rows from the left table.
4. Full Join (or Full Outer Join): This join returns rows when there is a match in one of the tables.
5. Cross Join: This join returns the Cartesian product of the two tables, i.e., all possible combinations of rows.

Understanding the differences between these types of joins is crucial for efficiently querying and retrieving data from your MySQL databases.
