hard🚀 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Understand inclusive range filtering
Inclusive means including 10 and 20, so use >= and <= operators.Step 2: Analyze each option
Price > 10 AND Price < 20 excludes 10 and 20 (strictly greater and less). Price >= 10 OR Price <= 20 uses OR, which selects too many rows. Price BETWEEN 10 AND 20 EXCLUSIVE is invalid syntax.Final Answer:
Price >= 10 AND Price <= 20 -> Option DQuick Check:
Inclusive range uses >= and <= with AND [OK]
Quick Trick: Use >= and <= with AND for inclusive ranges [OK]
Common Mistakes:
MISTAKES- Using > and < excludes boundary values
- Using OR instead of AND
- Trying invalid BETWEEN syntax
