Special SQL Joins Tutorial - Natural, Cross, and Self: SQL for Beginners

In this video, we will show you the different special joins you can use in PostgreSQL such as Natural Join, Cross Join, and Self Join. Natural join in PostgreSQL combines tables based on their common columns, automatically matching columns with the same name in both tables. Cross join, on the other hand, does not have a join predicate and creates a Cartesian product by combining every row from one table with every row from another table. Self join in PostgreSQL involves joining a table to itself and is useful for comparing or retrieving related data from different rows within the same table. 🌍 Get unlimited training with Simon Sez IT’s 170+ courses ⏩ https://www.simonsezit.com/courses/ 🚀 Level up your skills with a free 30-day trial to our complete training library of 8,500+ videos ⏩ https://www.simonsezit.com/ssit-first... 💻 Watch more free popular training tutorials from Simon Sez IT: 🔥Check out our FREE 300+ hour training course playlist here ➡️    • Simon Sez IT Long Training Courses   ✅ Check out our free video playlist for Data Analysis using Microsoft Tools 👉    • Data Analysis using Microsoft Tools   ✅Microsoft Access Training video playlist 👉    • How to Use Microsoft Access Training Tutor...   ✅ Microsoft Excel Beginner's Training here 👉    • Microsoft Excel Beginner's Training Tutorials   ✅ Introduction to Databases Training here 👉    • Introduction to Databases Training Tutorials   💬Stay in touch!
