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 update the specified row in the schema using the primary key in
21 -- the predicates.
22 -- 3) To trap any constraint violations that may have occurred.
23 -- 4) To raise any other errors.
24 --
25 -- Prerequisites:
26 -- This is an internal private procedure which must be called from the upd
27 -- procedure.
28 --
29 -- In Parameters:
30 -- A Pl/Sql record structre.
31 --
32 -- Post Success:
33 -- The specified row will be updated in the schema.
34 --
35 -- Post Failure:
36 -- If a check, unique or parent integrity constraint violation is raised the
37 -- constraint_error procedure will be called.
38 --
39 -- Developer Implementation Notes:
40 -- The update 'set' attribute list should be modified if any of your
41 -- attributes are not updateable.

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