In this tutorial, we will explore various types of SQL joins, understand their syntax, and learn through examples. By the end of this guide, you will have a solid understanding of how to use joins to fetch related data across tables efficiently.
In a relational database, data is organized in tables. Each table consists of rows and columns, with each row representing a unique record. Tables can be related to each other through keys, typically primary and foreign keys. Joins allow us to combine rows from two or more tables based on a related column between them.
