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.

240 -- {Start Of Comments}
241 --
242 -- Description:
243 --   The Convert_Defs procedure has one very important function:
244 --   It must return the record structure for the row with all system defaulted
245 --   values converted into its corresponding parameter value for update. When
246 --   we attempt to update a row through the Upd process , certain
247 --   parameters can be defaulted which enables flexibility in the calling of
248 --   the upd process (e.g. only attributes which need to be updated need to be
249 --   specified). For the upd process to determine which attributes
250 --   have NOT been specified we need to check if the parameter has a reserved
251 --   system default value. Therefore, for all parameters which have a
252 --   corresponding reserved system default mechanism specified we need to
253 --   check if a system default is being used. If a system default is being
254 --   used then we convert the defaulted value into its corresponding attribute
255 --   value held in the g_old_rec data structure.
256 --
257 -- Prerequisites:
258 --   This private function can only be called from the upd process.
259 --
260 -- In Parameters:
261 --   A Pl/Sql record structure.
262 --
263 -- Post Success:
264 --   The record structure will be returned with all system defaulted parameter
265 --   values converted into its current row attribute value.
266 --
267 -- Post Failure:
268 --   No direct error handling is required within this function. Any possible
269 --   errors within this procedure will be a PL/SQL value error due to
270 --   conversion of datatypes or data lengths.
