SQL Common Table Expression (CTE) explained in a real life scenario

SQL CTE explained in a real life scenario. In this video, I am exploring Common Table Expressions. CTE in SQL. One of the most powerful tools that helps you break complex queries into simple, readable steps. I used a customer sales example to show how you can first calculate total spending and then reuse that result like a table to answer important business questions. Instead of writing long and confusing subqueries, I showed how CTE allows you to prepare your data first and then filter it cleanly in a second step. Just like preparing food in the kitchen before serving it. Watch how I used CTE to find high value customers in a way that is easy for beginners and non technical people to understand. #SQL #DataAnalytics #LearningJourney #Database #CTE #SQLLearning
