17 -- Description:
18 -- This procedure controls the actual dml update logic. The processing of
19 -- this procedure is:
20 -- 1) Increment the object_version_number by 1 if the object_version_number
21 -- is defined as an attribute for this entity.
22 -- 2) To set and unset the g_api_dml status as required (as we are about to
23 -- perform dml).
24 -- 3) To update the specified row in the schema using the primary key in
25 -- the predicates.
26 -- 4) To trap any constraint violations that may have occurred.
27 -- 5) To raise any other errors.
28 --
29 -- Prerequisites:
30 -- This is an internal private procedure which must be called from the upd
31 -- procedure.
32 --
33 -- In Parameters:
34 -- A Pl/Sql record structre.
35 --
36 -- Post Success:
37 -- The specified row will be updated in the schema.
38 --
39 -- Post Failure:
40 -- On the update dml failure it is important to note that we always reset the
41 -- g_api_dml status to false.
42 -- If a check, unique or parent integrity constraint violation is raised the
43 -- constraint_error procedure will be called.
44 -- If any other error is reported, the error will be raised after the
45 -- g_api_dml status is reset.
46 --
47 -- Developer Implementation Notes:
48 -- The update 'set' attribute list should be modified if any of your
49 -- attributes are not updateable.

251 -- Description:
252 -- The Convert_Defs procedure has one very important function:
253 -- It must return the record structure for the row with all system defaulted
254 -- values converted into its corresponding parameter value for update. When
255 -- we attempt to update a row through the Upd process , certain
256 -- parameters can be defaulted which enables flexibility in the calling of
257 -- the upd process (e.g. only attributes which need to be updated need to be
258 -- specified). For the upd process to determine which attributes
259 -- have NOT been specified we need to check if the parameter has a reserved
260 -- system default value. Therefore, for all parameters which have a
261 -- corresponding reserved system default mechanism specified we need to
262 -- check if a system default is being used. If a system default is being
263 -- used then we convert the defaulted value into its corresponding attribute
264 -- value held in the g_old_rec data structure.
265 --
266 -- Prerequisites:
267 -- This private function can only be called from the upd process.
268 --
269 -- In Parameters:
270 -- A Pl/Sql record structure.
271 --
272 -- Post Success:
273 -- The record structure will be returned with all system defaulted parameter
274 -- values converted into its current row attribute value.
275 --
276 -- Post Failure:
277 -- No direct error handling is required within this function. Any possible
278 -- errors within this procedure will be a PL/SQL value error due to
279 -- conversion of datatypes or data lengths.
