A query is an operation that retrieves data from one or more tables or views. In this reference, a top-level SELECT
statement is called a query, and a query nested within another SQL statement is called a subquery.
This section describes some types of queries and subqueries and how to use them. The top level of the syntax is shown in this chapter.
