Become a Database Professional with SQL

In this module, you will explore Structured Query Language (SQL), mastering its core concepts through hands-on projects. You’ll start with fundamental SQL queries like SELECT query, SQL WHERE, etc. and gradually progress to using SQL DISTINCT, SQL GROUP BY, SQL ORDER BY, and SQL aggregate functions. You'll learn how to create and manage tables, compute new fields, and optimize data relationships using foreign keys. By the end, you will be adept at using SQL joins, SQL subqueries, and merging techniques to generate comprehensive reports.
