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.

26 -- Prerequisites:

28 -- procedure.

31 -- A Pl/Sql record structre.

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.

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

238 -- Post Success:

240 -- values converted into its current row attribute value.

242 -- Post Failure:
243 -- No direct error handling is required within this function. Any possible
244 -- errors within this procedure will be a PL/SQL value error due to conversion
245 -- of datatypes or data lengths.
