23 -- 4) To trap any constraint violations that may have occurred.
24 -- 5) To raise any other errors.

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

244 -- A Pl/Sql record structre.

246 -- Post Success:

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

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