Spec Pack UTL_RAW::

CREATE OR REPLACE PACKAGE SYS.utl_raw IS

------------
-- OVERVIEW
--
-- This package provides SQL functions for raws that concat,
-- substr, etc. to/from raws. This package is necessary
-- because normal SQL functions do not operate on raws and
-- PL/SQL does not allow overloading between a raw and a char
-- datatype. Also included are routines which convert various
-- COBOL number formats to/from raws.

-- UTL_RAW is not specific to the database environment and may
-- actually be used in other environments as it exists here.
-- For this reason, the prefix UTL has been given to the package
-- instead of DBMS.

-------
-- USES
--
-- The are many possible uses for the raw functions. The
-- functionality allows a raw "record" to be composed
-- of many elements. By using the raw datatype, character
-- set conversion will not be performed keeping the raw in
-- its original format when being transferred via rpc.
-- The raw functions also give the ability to manipulate
-- binary data which was previously limited to the hextoraw
-- and rawtohex functions.
