SQL identifiersdefinitionIdentifiersdefinitionAn identifier is the representation within the language of items created
by the user, as opposed to language keywords or commands. Dictionary
objectsdefinitionSome identifiers stand
for dictionary objects, which are the objects you create- such as tables,
views, indexes, columns, and constraints- that are stored in a database. They
are called dictionary objects because stores
information about them in the system tables, sometimes known as a data dictionary.
SQL also defines ways to alias these objects within certain statements.

representing dictionary objects must conform to SQL-92 identifier rules and
are thus called SQL92Identifiers.
