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