SQL – Talk to Databases Like a Pro

Every app has a database. Every company stores data. And the way you talk to databases? SQL. It's not a programming language like others – it's a query language. And it's actually pretty fun once you get it.

Hour 1 – Asking Questions to Databases:

Think of SQL as just asking questions. "Give me all users." "Show me orders from last month." "Who spent the most money?"

We'll:

• Set up a simple database (SQLite – no installation headaches)

• Learn SELECT – the most important word

• Filter with WHERE – get only what you need

• Sort with ORDER BY – oldest first? highest first? your choice

We'll practice on real datasets – movies, cricket players, your imaginary e-commerce store.

Hour 2 – Joins and Real Queries:

Now the good stuff:

• Combine data from multiple tables (JOIN) – like matching orders with customers

• Group data (GROUP BY) – total sales by month, average marks by class

• Update and delete (carefully!)

We'll build queries for real scenarios: "Find top 3 customers", "Products never ordered", "Students who improved this semester".

Who is this for? Beginners in data. Developers who've avoided databases. Anyone applying for jobs – SQL questions come up everywhere.

What you'll leave with: SQL skills that work in MySQL, PostgreSQL, any database. Ability to pull your own data. Confidence for interview questions.

Bring laptop. No database experience needed.
