Chapter 6. Identifiers

When you write SQL statements, you use names to refer to databases and objects contained in databases such as tables, stored routines, and triggers. Some of these objects have components with their own names. For example, tables have columns and indexes. It's also possible to create aliases, which act as synonyms for table and column names.

This chapter discusses the use of identifiers in SQL statements. It covers the following exam topics:

• Identifier syntax

• Identifier case sensitivity

• Using qualified names

• Using reserved words as identifiers
