This is a classic SQL interview trap question. Why is NULL = NULL false but IS NULL true in SQL? 1️⃣ NULL means β€œunknown” In SQL, NULL is not a value. It represents missing or unknown data. βΈ» 2️⃣ Comparison with unknown is unknown When you write: NULL = NULL You are comparing unknown with unknown β†’ result is UNKNOWN, not TRUE. 3️⃣ SQL uses three-valued logic SQL has: β€’TRUE β€’FALSE β€’UNKNOWN NULL = NULL β†’ UNKNOWN β†’ treated as FALSE in conditions. 4️⃣ IS NULL is a special check: column IS NULL This does not compare values. It checks whether the value is missing β†’ returns TRUE. 🎯 Interview takeaway = compares values IS NULL checks existence NULL is not equal to anything β€” not even itself. { SQL, Databases, BackendDeveloper, SoftwareDevelopment, Programming, DatabaseConcepts, SystemDesign, ComputerScience, TechCareers, InterviewPrep } #SQL #Databases #BackendEngineering #SystemDesign #TechExplained
