30 -- Description:
31 -- This procedure is called when a constraint has been violated (i.e.
32 -- The exception hr_api.check_integrity_violated,
33 -- hr_api.parent_integrity_violated, hr_api.child_integrity_violated or
34 -- hr_api.unique_integrity_violated has been raised).
35 -- The exceptions can only be raised as follows:
36 -- 1) A check constraint can only be violated during an INSERT or UPDATE
37 -- dml operation.
38 -- 2) A parent integrity constraint can only be violated during an
39 -- INSERT or UPDATE dml operation.
40 -- 3) A child integrity constraint can only be violated during an
41 -- DELETE dml operation.
42 -- 4) A unique integrity constraint can only be violated during INSERT or
43 -- UPDATE dml operation.
44 --
45 -- Prerequisites:
46 -- 1) Either hr_api.check_integrity_violated,
47 -- hr_api.parent_integrity_violated, hr_api.child_integrity_violated or
48 -- hr_api.unique_integrity_violated has been raised with the subsequent
49 -- stripping of the constraint name from the generated error message
50 -- text.
51 -- 2) Standalone validation test which corresponds with a constraint error.
52 --
53 -- In Parameter:
54 -- p_constraint_name is in upper format and is just the constraint name
55 -- (e.g. not prefixed by brackets, schema owner etc).
56 --
57 -- Post Success:
58 -- Development dependant.
59 --
60 -- Post Failure:
61 -- Developement dependant.
62 --
63 -- Developer Implementation Notes:
64 -- For each constraint being checked the hr system package failure message
65 -- has been generated as a template only. These system error messages should
66 -- be modified as required (i.e. change the system failure message to a user
67 -- friendly defined error message).

82 -- Description:
83 -- This function is used to populate the g_old_rec record with the
84 -- current row from the database for the specified primary key
85 -- provided that the primary key exists and is valid and does not
86 -- already match the current g_old_rec. The function will always return
87 -- a TRUE value if the g_old_rec is populated with the current row.
88 -- A FALSE value will be returned if all of the primary key arguments
89 -- are null.
90 --
91 -- Prerequisites:
92 -- None.
93 --
94 -- In Parameters:
95 --
96 -- Post Success:
97 -- A value of TRUE will be returned indiciating that the g_old_rec
98 -- is current.
99 -- A value of FALSE will be returned if all of the primary key arguments
100 -- have a null value (this indicates that the row has not be inserted into
101 -- the Schema), and therefore could never have a corresponding row.
102 --
103 -- Post Failure:
104 -- A failure can only occur under two circumstances:
105 -- 1) The primary key is invalid (i.e. a row does not exist for the
106 -- specified primary key values).
107 -- 2) If an object_version_number exists but is NOT the same as the current
108 -- g_old_rec value.

130 -- Description:
131 -- This procedure will update the specified datetrack row with the
132 -- specified new effective end date. The object version number is also
133 -- set to the next object version number. DateTrack modes which call
134 -- this procedure are: UPDATE, UPDATE_CHANGE_INSERT,
135 -- UPDATE_OVERRIDE, DELETE, FUTURE_CHANGE and DELETE_NEXT_CHANGE.
136 -- This is an internal datetrack maintenance procedure which should
137 -- not be modified in anyway.
138 --
139 -- Prerequisites:
140 -- None.
141 --
142 -- In Parameters:
143 -- p_new_effective_end_date
144 -- Specifies the new effective end date which will be set for the
145 -- row as of the effective date.
146 -- p_base_key_value
147 -- Specifies the primary key value for this datetrack entity.
148 -- (E.g. For this entity the assignment of the argument would be:
149 -- p_base_key_value = :condition_id).
150 --
151 -- Post Success:
152 -- The specified row will be updated with the new effective end date and
153 -- object_version_number.
154 --
155 -- Post Failure:
156 -- Failure might occur if for the specified effective date and primary key
157 -- value a row doesn't exist.

181 -- Description:
182 -- The Lck process for datetrack is complicated and comprises of the
183 -- following processing
184 -- The processing steps are as follows:
185 -- 1) The row to be updated or deleted must be locked.
186 -- By locking this row, the g_old_rec record data type is populated.
187 -- 2) If a comment exists the text is selected from hr_comments.
188 -- 3) The datetrack mode is then validated to ensure the operation is
189 -- valid. If the mode is valid the validation start and end dates for
190 -- the mode will be derived and returned. Any required locking is
191 -- completed when the datetrack mode is validated.
192 --
193 -- Prerequisites:
194 -- When attempting to call the lck procedure the object version number,
195 -- primary key, effective date and datetrack mode must be specified.
196 --
197 -- In Parameters:
198 -- p_effective_date
199 -- Specifies the date of the datetrack update operation.
200 -- p_datetrack_mode
201 -- Determines the datetrack update or delete mode.
202 --
203 -- Post Success:
204 -- On successful completion of the Lck process the row to be updated or
205 -- deleted will be locked and selected into the global data structure
206 -- g_old_rec.
207 --
208 -- Post Failure:
209 -- The Lck process can fail for three reasons:
210 -- 1) When attempting to lock the row the row could already be locked by
211 -- another user. This will raise the HR_Api.Object_Locked exception.
212 -- 2) The row which is required to be locked doesn't exist in the HR Schema.
213 -- This error is trapped and reported using the message name
214 -- 'HR_7220_INVALID_PRIMARY_KEY'.
215 -- 3) The row although existing in the HR Schema has a different object
216 -- version number than the object version number specified.
217 -- This error is trapped and reported using the message name
218 -- 'HR_7155_OBJECT_INVALID'.
