Advanced Statements

In the previous chapter, we started taking our first steps with PostgreSQL. In this chapter, we will analyze the SQL language more deeply and write more complex queries. We will talk about SELECT/INSERT/UPDATE again, but this time, we will use the more advanced options surrounding them. We will then cover JOIN and common table expressions (CTEs) in depth.

The topics we will talk about will be the following:

Exploring the SELECT statement
Using UPSERT
Exploring CTEs
