15 -- Description:
16 -- This procedure controls the actual dml update logic. The processing of
17 -- this procedure is:

19 -- is defined as an attribute for this entity.
20 -- perform dml).
21 -- 3) To update the specified row in the schema using the primary key in
22 -- the predicates.
23 -- 4) To trap any constraint violations that may have occurred.
24 -- 5) To raise any other errors.
25 --
26 -- Prerequisites:
27 -- This is an internal private procedure which must be called from the upd
28 -- procedure.
29 --
30 -- In Parameters:
31 -- A Pl/Sql record structre.
32 --
33 -- Post Success:
34 -- The specified row will be updated in the schema.

36 -- Post Failure:
37 -- On the update dml failure it is important to note that we always reset the
38 -- If a check, unique or parent integrity constraint violation is raised the
39 -- constraint_error procedure will be called.
40 -- If any other error is reported, the error will be raised after the

44 -- attributes are not updateable.

181 -- Description:
182 -- The Convert_Defs procedure has one very important function:
183 -- It must return the record structure for the row with all system defaulted
184 -- values converted into its corresponding parameter value for update. When
185 -- we attempt to update a row through the Upd process , certain
186 -- parameters can be defaulted which enables flexibility in the calling of
187 -- the upd process (e.g. only attributes which need to be updated need to be
188 -- specified). For the upd process to determine which attributes
189 -- have NOT been specified we need to check if the parameter has a reserved
190 -- system default value. Therefore, for all parameters which have a
191 -- corresponding reserved system default mechanism specified we need to
192 -- check if a system default is being used. If a system default is being
193 -- used then we convert the defaulted value into its corresponding attribute
194 -- value held in the g_old_rec data structure.
195 --
196 -- Prerequisites:
197 -- This private function can only be called from the upd process.
198 --
199 -- In Parameters:
200 -- A Pl/Sql record structre.
201 --
202 -- Post Success:
203 -- The record structure will be returned with all system defaulted parameter
204 -- values converted into its current row attribute value.
205 --
206 -- Post Failure:
207 -- No direct error handling is required within this function. Any possible
208 -- errors within this procedure will be a PL/SQL value error due to conversion
209
210 -- of datatypes or data lengths.
