Syntax for SQL Statements

SQL statements are the means by which programs and users access data in an Oracle database.

The sections that follow show each SQL statement and its related syntax. Refer to Chapter 5, "Subclauses" for the syntax of the subclauses listed in the syntax for the statements.
