Identifiers

An identifier is a token used to form a name. An identifier in an SQL statement is an SQL identifier, a system identifier, or a host identifier.

Note: $, @, #, and all other variant characters should not be used in identifiers because the code points used to represent them vary depending on the CCSID of the string in which they are contained. If they are used, unpredictable results may occur. For more information about variant characters, see the DB2® and SQL sort sequence topic.
