Nested records

Nested records are records contained in fields that are records themselves. Nesting records is a powerful way to normalize data structures and hide complexity within PL/SQL programs. For example:

DECLARE
   -- Define a record.
   TYPE phone_rectype IS RECORD (
      area_code  VARCHAR2(3),
      exchange   VARCHAR2(3),
      phn_number VARCHAR2(4),
      extension  VARCHAR2(4));

   -- Define a record composed of records.
   TYPE contact_rectype IS RECORD (
      day_phone#  phone_rectype,
      eve_phone#  phone_rectype,
      cell_phone# phone_rectype);

-- Declare a variable for the nested record.
 auth_rep_info_rec contact_rectype;
