When an applications programmer or end user creates a database object or refers to it by
name, case is unimportant. The following limitations on naming database objects must
be observed:
— Start each name with an alphabetic character (A–Z or a–z).
— Restrict object names to 31 characters, including dollar signs ($), underscores (_), 0 to 9,
A to Z, and a to z. Some objects, such as constraint names, are restricted to 27 bytes in
length.
— Keep object names unique. In all cases, objects of the same type—all tables, for
example—must be unique. In most cases, object names must also be unique within the
database.
— To use keywords, ASCII characters, case-sensitive strings, or spaces in an object name,
enclose the name in double quotes. It is then a delimited identifier. Delimited identifiers
must always be referenced in double quotes.
