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.

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