What will I learn?

Intro to SQL Course gives you practical skills to query and manage relational databases with confidence. Learn SELECT, filtering, sorting, aggregation, and joins, then move into subqueries, EXISTS, and performance basics with indexes and EXPLAIN. You also design tables, define keys and constraints, and practice safe INSERT, UPDATE, DELETE, and transaction workflows for reliable, production-ready data work.
