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

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

130 -- Description:
131 -- The Lck process has two main functions to perform. Firstly, the row to be
132 -- updated or deleted must be locked. The locking of the row will only be
133 -- successful if the row is not currently locked by another user.
134 -- Secondly, during the locking of the row, the row is selected into
135 -- the g_old_rec data structure which enables the current row values from
136 -- the server to be available to the api.
137 --
138 -- Prerequisites:
139 -- When attempting to call the lock the object version number (if defined)
140 -- is mandatory.
141 --
142 -- In Parameters:
143 -- The arguments to the Lck process are the primary key(s) which uniquely
144 -- identify the row and the object version number of row.
145 --
146 -- Post Success:
147 -- On successful completion of the Lck process the row to be updated or
148 -- deleted will be locked and selected into the global data structure
149 -- g_old_rec.
150 --
151 -- Post Failure:
152 -- The Lck process can fail for three reasons:
153 -- 1) When attempting to lock the row the row could already be locked by
154 -- another user. This will raise the HR_Api.Object_Locked exception.
155 -- 2) The row which is required to be locked doesn't exist in the HR Schema.
156 -- This error is trapped and reported using the message name
157 -- 'HR_7220_INVALID_PRIMARY_KEY'.
158 -- 3) The row although existing in the HR Schema has a different object
159 -- version number than the object version number specified.
160 -- This error is trapped and reported using the message name
161 -- 'HR_7155_OBJECT_INVALID'.
162 --
163 -- Developer Implementation Notes:
164 -- For each primary key and the object version number arguments add a
165 -- call to hr_api.mandatory_arg_error procedure to ensure that these
166 -- argument values are not null.
