To become proficient in SQL joins, it's essential to practice consistently and effectively. Start by utilizing online resources such as W3Schools, SQL Fiddle, and LeetCode, which offer interactive SQL environments and exercises to help you hone your skills. Practice with sample databases like Northwind, Sakila, or AdventureWorks, which provide a realistic setting to apply your knowledge. Begin with simple INNER JOIN, LEFT JOIN, and RIGHT JOIN exercises, and gradually move on to more advanced joins like FULL OUTER JOIN, CROSS JOIN, and SELF JOIN. As you progress, try applying joins to real-world scenarios, such as combining customer and order data, to reinforce your understanding. By experimenting with different join types and analyzing the results, you'll develop a deeper understanding of SQL joins and become proficient in using them to extract valuable insights from complex data sets.

I need your help to choose my career as I have three years of gap between my education. I know SQL. Can anyone tell me should I choose MS SQL server or oracle because I am interested in the database? Which one will be better to learn to get into the IT industry? Please help me! Thank you!
As you are strong and interested in SQL, why not to choose ETL Testing? It has a good career ahead in data projects. To survive in the market, you need both Oracle & SQL Server. Actually, both are almost same but are different products.
