Query Clauses 🔍¶
Mentor's Note: A raw
SELECTgives you a mountain of data. Clauses are the tools you use to "carve" that mountain into a precise statue. This module teaches you how to filter, sort, and organize your results. 💡
🏗️ What you will learn:¶
- WHERE: Precise row-level filtering.
- ORDER BY: Sorting data logically (A-Z, High-Low).
- DISTINCT: Removing visual duplicates.
- LIMIT / TOP: Pagination for modern apps.
- WITH (CTE): Advanced modular query building.
