In a normalized database, data related to an entity may be stored in multiple tables. When you need to view data from related tables together, you can join the tables with the help of common attributes.

You can also use subqueries where the result of a query is used as an input for the condition of another query. In addition, you can store the result of a query as a temporary result set by using Common Table Expressions (CTE). This temporary result set exists only within the scope of a single SQL statement.

This blog post discusses how to query data from multiple tables by applying various types of joins, such as an inner join, outer join cross join, equi join, or self join. Further, it explains how to use subqueries. Lately, this chapter discusses temporary result sets created by using CTE.
