This course takes you deep into the world of SQL — not just how, but why it works. Start with core concepts like SELECT, WHERE, and JOINS, then level up to advanced tools like window functions, correlated subqueries, CTEs, and recursive CTEs. You'll also explore how SQL queries are parsed, optimized, and executed by the database engine, giving you a behind-the-scenes view of performance tuning and execution plans. Designed for analysts, developers, and aspiring data engineers — this is the SQL you wish you learned earlier.
SQL (Structured Query Language) is the standard language used to communicate with databases. This course covers everything from basic SQL syntax to advanced querying techniques, enabling you to efficiently manage and analyze data.
You will learn how to create, read, update, and delete data (CRUD operations), design and manage relational databases, use joins to combine data from multiple tables, apply filtering and sorting, and write complex queries with subqueries and aggregate functions.
