Whether you're a complete beginner, someone who just finished our SQL Basics in MS SQL Server course, or an SQL Server enthusiast who's simply eager to hone their skills, there's always room for improvement. This practice set will test your basic SQL knowledge and will show you where you need to improve. Remember that mastering SQL is a hands-on experience - learning the concepts is one thing, but writing good queries requires practice.

The scope of this practice set includes:

  • simple SELECT queries;
  • aggregate functions (COUNT(), SUM(), AVG());
  • grouping and ordering results;
  • JOINs (querying from multiple tables, self joins, LEFT JOIN, RIGHT JOIN, and non-equi JOINs);
  • subqueries (simple subqueries, subqueries with multiple results, correlated subqueries, and subqueries in the FROM and SELECT clauses).

The last two parts of the course comprise a special challenge that combines all of the above material for a comprehensive review.
