SQL Interview Question: How to handle divide by zero in SQL using exception handling Most beginners write a simple division query and it works… until real data shows up. The moment total_orders becomes zero, your query throws a runtime error and fails. This is one of the most common mistakes asked in SQL interviews. In this video, you’ll learn how to handle divide by zero in SQL using NULLIF, a simple but powerful technique for exception handling. Instead of breaking your query, you’ll safely convert problematic values and keep your execution smooth. If you’re preparing for SQL interviews or working on real-world data analysis, this concept is a must-know. Comment NULLIF and I’ll send you a practice worksheet to master this. ------------------------------------------------------------------------ ►►►LINKS◄◄◄ Blog: Previous Tutorial ► ============================= ►►►Camera Gears https://www.amazon.in/shop/manishsharma?listId=DU9UM0XL97KM&ref=idea_share_inf ►►► Work From Home Essential Tech That We Use Daily https://www.amazon.in/shop/manishsharma?listId=XAZ18JLLSNB5&ref=idea_share_inf ============================= ============================= Subscribe now for more database tutorials ============================= @RebellionRider ============================= ►►►Connect With Us ============================= https://www.instagram.com/RebellionRider/ https://www.facebook.com/TheRebellionRider/ https://twitter.com/RebellionRider https://www.linkedin.com/in/mannbhardwaj/ ============================= ►►►Books I refer to ============================= 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.
