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

223 -- Description:
224 -- The Convert_Defs procedure has one very important function:
225 -- It must return the record structure for the row with all system defaulted
226 -- values converted into its corresponding parameter value for update. When
227 -- we attempt to update a row through the Upd process , certain
228 -- parameters can be defaulted which enables flexibility in the calling of
229 -- the upd process (e.g. only attributes which need to be updated need to be
230 -- specified). For the upd process to determine which attributes
231 -- have NOT been specified we need to check if the parameter has a reserved
232 -- system default value. Therefore, for all parameters which have a
233 -- corresponding reserved system default mechanism specified we need to
234 -- check if a system default is being used. If a system default is being
235 -- used then we convert the defaulted value into its corresponding attribute
236 -- value held in the g_old_rec data structure.
237 --
238 -- Prerequisites:
239 -- This private function can only be called from the upd process.

242 -- A Pl/Sql record structure.

244 -- Post Success:

248 -- Post Failure:
249 -- No direct error handling is required within this function. Any possible
250 -- errors within this procedure will be a PL/SQL value error due to conversion
251
252 -- of datatypes or data lengths.
