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.

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

253 -- A Pl/Sql record structre.
254 --
255 -- Post Success:

257 -- values converted into its current row attribute value.
258 --
259 -- Post Failure:
260 -- No direct error handling is required within this function. Any possible
261 -- errors within this procedure will be a PL/SQL value error due to conversion
262 -- of datatypes or data lengths.
