1.2. Naming in SQL
Most naming requirements in SQL are actually requirements of the Oracle database; names that are acceptable for schema objects (defined in the next section) in the Oracle database are acceptable in SQL, and vice versa. The following rules apply to the names of schema objects in Oracle:
They may comprise 1 to 30 alphanumeric characters.
They must begin with a letter.
They may include an underscore ( _ ).
They may include a dollar ($) or pound sign (#), although Oracle discourages the use of these characters.
They may not be a reserved word.
They may not be the name of a SQL command.
