Intro to SQL: Querying and Managing Data
About this course
SQL is one of the most universally required skills across data and software roles, and Khan Academy's free introduction covers the essentials: writing SELECT queries, filtering and sorting data, joining tables, and basic data manipulation (INSERT, UPDATE, DELETE). It's taught through Khan Academy's signature interactive exercise format, where you write real SQL against real datasets rather than watching passive demonstrations.
Because SQL knowledge underlies so many other courses in this catalog — data analytics certificates, data science programs, even some cloud and AI courses — this is a useful, free prerequisite for learners who hit SQL syntax in an applied course and need a dedicated refresher rather than learning it for the first time mid-course.
