WHERE Clause in SQL Explained with Coding 🔥 | AND, OR, BETWEEN, IN, LIKE, NULL | SQL Tutorial

Описание: In this video, I explain the WHERE clause in SQL in a simple and practical way with live coding examples using a Students table.

00:00 – Introduction to WHERE Clause
01:16 – Comparison Operators Explained
03:32 – AND, OR, NOT Operators
07:29 – BETWEEN & IN Operators
10:50 – LIKE Operator (Pattern Matching)
14:19 – IS NULL & IS NOT NULL

The WHERE clause is one of the most important concepts in SQL because it allows you to filter data based on conditions.

👉 In simple words:
WHERE tells SQL — “Show only those rows that satisfy this condition.”

If you are preparing for SQL interviews, DBMS exams, or backend development, this topic is absolutely essential.
