15 -- Description:
16 -- This procedure controls the actual dml delete logic. The functions of
17 -- this procedure are as follows:
18 -- 1) To delete the specified row from the schema using the primary key in
19 -- the predicates.
20 -- 2) To trap any constraint violations that may have occurred.
21 -- 3) To raise any other errors.
22 --
23 -- Prerequisites:
24 -- This is an internal private procedure which must be called from the del
25 -- procedure.
26 --
27 -- In Parameters:
28 -- A Pl/Sql record structre.
29 --
30 -- Post Success:
31 -- The specified row will be delete from the schema.
32 --
33 -- Post Failure:
34 -- If a child integrity constraint violation is raised the
35 -- constraint_error procedure will be called.
36 --
37 -- Developer Implementation Notes:
38 -- None.

40 -- Access Status:
41 -- Internal Row Handler Use Only.
