> IS NULL Operator - Why IS NULL? We covered NULL before - let's consolidate it here completely in the context of WHERE. Use IS NULL and IS NOT NULL to check for NULL values. Never use = NULL or != NULL — they will never work! ~IS NULL: -- Employees with NO commission: SELECT name, commission FROM employees WHERE commission IS NULL; Output: Name | Commission Priya | NULL Neha | NULL Suresh | NULL Meera | NULL ~IS NOT NULL: -- Employees WHO HAVE commission: SELECT name, commission FROM employees WHERE commission IS NOT NULL; Output: Name | Commission Raj | 5000 Arjun | 3000 Kavya | 2000 Vikram | 8000 > Why = NULL Never Works: WHERE commission = NULL -- Returns 0 rows ❌ ALWAYS! WHERE commission IS NULL -- Works correctly ✅ Because NULL means unknown. Oracle can't confirm if unknown = unknown. Think of it as: "Is mystery box 1 equal to mystery box 2?" You can't know - both are unknown! > Quick Summary: • IN = match against a specific list - much cleaner than multiple OR conditions • NOT IN works - but NEVER put NULL in the list or you get zero results • Use IN for discrete specific values, BETWEEN for continuous ranges • LIKE = pattern search using wildcards • % = any number of characters (zero or more) • _ = exactly one character • Data is case sensitive - use UPPER() with LIKE for safety • ESCAPE lets you search for literal % or _ characters • IS NULL = only correct way to check for NULL • = NULL always returns zero rows - never use it #OracleSQL #INOperator #LIKEOperator #ISNull #Wildcards #LearnSQL #SQLBeginners #Day13 #100DaysOfCode #TechTwitter
