Review and deepen your knowledge of SQL JOINs with 93 exercises. Practice common and less common ways of getting data from multiple tables.
JOINs are one of the most fundamental and commonly used features of the SQL language. It's safe to say that at least basic knowledge of querying data from more than one table is an absolute must for every SQL user.
This course covers all important types of SQL JOINs that are widely used by SQL programmers to query databases on a daily basis.
This course is intended for users who have very basic experience with SQL. We assume you know how to write simple queries to select data from a single table.
Just a web browser and an Internet connection.
You'll also delve into the interesting topic of non-equi JOINs.
