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