16 -- Description:
17 -- This procedure controls the actual dml delete logic. The functions of
18 -- this procedure are as follows:
19 -- 1) To set and unset the g_api_dml status as required (as we are about to
20 -- perform dml).
21 -- 2) To delete the specified row from the schema using the primary key in
22 -- the predicates.
23 -- 3) To trap any constraint violations that may have occurred.
24 -- 4) To raise any other errors.
25 --
26 -- Prerequisites:
27 -- This is an internal private procedure which must be called from the del
28 -- procedure.
29 --
30 -- In Parameters:
31 -- A Pl/Sql record structre.
32 --
33 -- Post Success:
34 -- The specified row will be delete from the schema.
35 --
36 -- Post Failure:
37 -- On the delete dml failure it is important to note that we always reset the
38 -- g_api_dml status to false.
39 -- If a child integrity constraint violation is raised the
40 -- constraint_error procedure will be called.
41 -- If any other error is reported, the error will be raised after the
42 -- g_api_dml status is reset.
43 --
44 -- Developer Implementation Notes:
45 -- None.
46 --
47 -- Access Status:
48 -- Internal Row Handler Use Only.
