I once thought my SQL report was perfect—until joins started failing and nothing made sense. Turns out, messy data was the real culprit. That’s when I learned how to clean data using SQL. A simple TRIM (SQL string function) removed hidden spaces, and REPLACE (SQL string function) fixed inconsistent values like ‘Bombay’ vs ‘Mumbai’. Don’t wait for errors to teach you—clean your data before it breaks things. My book has tons of practical SQL tips you’ll actually use. 🎯 Buy The MUST HAVE Book for Data Professionals here📘💡https://dataprofy.com/product-category/ebook/ ============ Watch how to configure Oracle on VS Code https://youtu.be/6mwAx4sGhwk Explore the complete PL/SQL course for FREE on my website at https://www.rebellionrider.com/category/pl-sql/ ============ The camera gear I use in my Videos https://www.amazon.in/shop/manishsharma?listId=DU9UM0XL97KM&ref=idea_share_inf ============ Connect With Me on My Social Media https://www.instagram.com/RebellionRider/ https://www.facebook.com/TheRebellionRider/ https://twitter.com/RebellionRider https://www.linkedin.com/in/mannbhardwaj/ ============ FAQ Which book to refer to learn - PL/SQL https://amzn.to/2QE1jX0 Performance Tuning https://amzn.to/2sgiAw4 1z0-071 Exam https://amzn.to/2sgfeJw Python Programming https://amzn.to/305UEbh ============ AFFILIATE DISCLOSURE: Some of the links used in the description will direct you to Amazon.in.
