SQL Tutorial

SQL Tutorial is a free educational website for learning SQL and relational database concepts. The tutorial introduces SQL language basics, relational database management systems, common clauses and important tasks such as selecting, inserting, updating and deleting data.

The lessons move from introductory SQL concepts to practical statements such as SELECT, WHERE, UPDATE and DELETE, then continue into table relationships, primary keys, foreign keys, normalization, joins, views and indexes. The site also explains that different database systems may use their own SQL dialects while still sharing many core concepts.

Students, new developers and database beginners can use the website as a plain-language starting point before moving into database-specific documentation or practice environments. Readers exploring broader software material can use the tutorial to strengthen basic database vocabulary and understand how SQL is used to store, retrieve and manage structured data.
