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

235 -- Description:
236 -- The Convert_Defs procedure has one very important function:
237 -- It must return the record structure for the row with all system defaulted
238 -- values converted into its corresponding parameter value for update. When
239 -- we attempt to update a row through the Upd process , certain
240 -- parameters can be defaulted which enables flexibility in the calling of
241 -- the upd process (e.g. only attributes which need to be updated need to be
242 -- specified). For the upd process to determine which attributes
243 -- have NOT been specified we need to check if the parameter has a reserved
244 -- system default value. Therefore, for all parameters which have a
245 -- corresponding reserved system default mechanism specified we need to
246 -- check if a system default is being used. If a system default is being
247 -- used then we convert the defaulted value into its corresponding attribute
248 -- value held in the g_old_rec data structure.
249 --
250 -- Prerequisites:
251 -- This private function can only be called from the upd process.
252 --

254 -- A Pl/Sql record structure.
255 --
256 -- Post Success:
257 -- The record structure will be returned with all system defaulted parameter
258 -- values converted into its current row attribute value.
259 --
260 -- Post Failure:
261 -- No direct error handling is required within this function. Any possible
262 -- errors within this procedure will be a PL/SQL value error due to
263 -- conversion of datatypes or data lengths.
