SQL WHERE Clause | AND, OR, NOT | SQL for Beginners

In Chapter 2 (Part 1), we move beyond selecting all rows and learn how to filter data precisely using the SQL WHERE clause. Whether you are a student preparing for exams or a fresher aiming for a data analyst role, understanding how to filter data is the most critical step after the basic SELECT statement. We break down how to act as a "gatekeeper" for your data, keeping only the rows that match your specific conditions 📘 In this video, you will learn: The Problem: Why we can't just use SELECT * for millions of rows. The Solution: Using the WHERE clause syntax strictly after the FROM clause. Visual Flow: How SQL decides to "Keep" or "Drop" a row based on conditions. Logical Operators: AND: When both conditions must be true (e.g., IT Dept AND Delhi). OR: When at least one condition must be true. NOT: How to invert results (e.g., NOT in IT). 📺 About Our Channel Welcome to MyCampus – your go-to place for clear and concise tutorials on Data Science, Machine Learning, Mathematics, and Programming.
