SQL Episode #12 - Learn SQL Joins in the Easiest Way! | Tech Skill Boost !

Joins are the key to retrieving data from multiple tables in SQL!

Example: Using Department & Employee tables — we join them using a common column like DepartmentID to get meaningful combined data.
Here are the 5 types of SQL Joins you MUST know:

🔹 Inner Join – Returns only matching records
🔹 Outer Join – Returns matching + non-matching
  ◼ Left Outer
  ◼ Right Outer
  ◼ Full Outer
🔹 Cross Join – Returns all possible combinations
🔹 Self Join – Join the table with itself!
Mastering these joins will level-up your database skills and boost your career in IT, Data Engineering, Analytics, and Software Development.
