Day 29 Night Study | SQL Learning Journey Tonight, I explored the CASE expression in SQL, and it’s one of those concepts that makes your queries smarter and more dynamic. The CASE expression works like an if-then-else statement in SQL. It allows you to return different results based on specific conditions. 1. It checks conditions one by one 2. Stops at the first condition that is true 3. Returns the result for that condition 4.If none match, it returns the ELSE value 5. If there’s no ELSE, it returns as NULL Basic Syntax for CASE expression in SQL: CASE WHEN condition1 THEN result1 WHEN condition2 THEN result2 ... ELSE default_result END; The SQL CASE expression helps in the following ways: 1. Categorization of data 2.Creating conditional outputs 3.Makes queries more flexible and readable #SQL #Data Analytics#NightStudy #LearningJourney #BeginnerFriendly #DataSkills #TechGrowth
