10 -- Description:
11 -- This procedure controls the actual dml delete logic. The functions of
12 -- this procedure are as follows:
13 -- 1) To set and unset the g_api_dml status as required (as we are about to
14 -- perform dml).
15 -- 2) To delete the specified row from the schema using the primary key in
16 -- the predicates.
17 -- 3) To trap any constraint violations that may have occurred.
18 -- 4) To raise any other errors.
19 --
20 -- Prerequisites:
21 -- This is an internal private procedure which must be called from the del
22 -- procedure.
23 --
24 -- In Parameters:
25 -- A Pl/Sql record structre.
26 --
27 -- Post Success:
28 -- The specified row will be delete from the schema.
29 --
30 -- Post Failure:
31 -- On the delete dml failure it is important to note that we always reset the
32 -- g_api_dml status to false.
33 -- If a child integrity constraint violation is raised the
34 -- constraint_error procedure will be called.
35 -- If any other error is reported, the error will be raised after the
36 -- g_api_dml status is reset.

212 -- row from the HR schema. This process is the main backbone of the del
213 -- business process. The processing of this procedure is as follows:
214 -- 1) The controlling validation process delete_validate is then executed
215 -- which will execute all private and public validation business rule
216 -- processes.
217 -- 2) The pre_delete process is then executed which enables any
218 -- logic to be processed before the delete dml process is executed.
219 -- 3) The delete_dml process will physical perform the delete dml for the
220 -- specified row.
221 -- 4) The post_delete process is then executed which enables any
222 -- logic to be processed after the delete dml process.
223 --
224 -- Prerequisites:
225 -- The main parameters to the business process have to be in the record
226 -- format.

228 -- In Parameters:

287 -- This procedure is the attribute interface for the delete

291 -- 1) The attributes are converted into a local record structure by
292 -- explicitly coding the attribute parameters into the g_rec_type
293 -- datatype.
294 -- 2) After the conversion has taken place, the corresponding record del
