1.1 What Is SQL in Simple Words (Ask Questions of Tables)

Why. Managers ask questions. Tables hold answers. You need a clear way to ask.

What. SQL (Structured Query Language) is the language you use to ask a database for rows that match your question.

How. Think: table = sheet, row = one record, column = one field. SELECT asks for columns; WHERE keeps matching rows.

SELECT city, amount_inr
FROM orders
LIMIT 5;
