28 -- Description:
29 -- This function will return the current g_api_dml private global
30 -- boolean status.
31 -- The g_api_dml status determines if at the time of the function
32 -- being executed if a dml statement (i.e. INSERT, UPDATE or DELETE)
33 -- is being issued from within an api.
34 -- If the status is TRUE then a dml statement is being issued from
35 -- within this entity api.
36 -- This function is primarily to support database triggers which
37 -- need to maintain the object_version_number for non-supported
38 -- dml statements (i.e. dml statement issued outside of the api layer).
39 --
40 -- Prerequisites:
41 -- none
42 --
43 -- In Parameters:
44 -- None.
45 --
46 -- Post Success:
47 -- Processing continues.
48 -- If the function returns a TRUE value then, dml is being executed from
49 -- within this api.
50 --
51 -- Post Failure:
52 -- None.

67 -- Description:
68 -- This procedure is called when a constraint has been violated (i.e.
69 -- The exception hr_api.check_integrity_violated,
70 -- hr_api.parent_integrity_violated, hr_api.child_integrity_violated or
71 -- hr_api.unique_integrity_violated has been raised).
72 -- The exceptions can only be raised as follows:
73 -- 1) A check constraint can only be violated during an INSERT or UPDATE
74 -- dml operation.
75 -- 2) A parent integrity constraint can only be violated during an
76 -- INSERT or UPDATE dml operation.
77 -- 3) A child integrity constraint can only be violated during an
78 -- DELETE dml operation.
79 -- 4) A unique integrity constraint can only be violated during INSERT or
80 -- UPDATE dml operation.
81 --
82 -- Prerequisites:
83 -- 1) Either hr_api.check_integrity_violated,
84 -- hr_api.parent_integrity_violated, hr_api.child_integrity_violated or
85 -- hr_api.unique_integrity_violated has been raised with the subsequent
86 -- stripping of the constraint name from the generated error message
87 -- text.
88 -- 2) Standalone validation test which corresponds with a constraint error.
89 --
90 -- In Parameter:
91 -- p_constraint_name is in upper format and is just the constraint name
92 -- (e.g. not prefixed by brackets, schema owner etc).
93 --
94 -- Post Success:
95 -- Development dependant.
96 --
97 -- Post Failure:
98 -- Developement dependant.
99 --
100 -- Developer Implementation Notes:
101 -- For each constraint being checked the hr system package failure message
102 -- has been generated as a template only. These system error messages should
103 -- be modified as required (i.e. change the system failure message to a user
104 -- friendly defined error message).

119 -- Description:
120 -- This function is used to populate the g_old_rec record with the
121 -- current row from the database for the specified primary key
122 -- provided that the primary key exists and is valid and does not
123 -- already match the current g_old_rec. The function will always return
124 -- a TRUE value if the g_old_rec is populated with the current row.
125 -- A FALSE value will be returned if all of the primary key arguments
126 -- are null.
127 --
128 -- Prerequisites:
129 -- None.
130 --
131 -- In Parameters:
132 --
133 -- Post Success:
134 -- A value of TRUE will be returned indiciating that the g_old_rec
135 -- is current.
136 -- A value of FALSE will be returned if all of the primary key arguments
137 -- have a null value (this indicates that the row has not be inserted into
138 -- the Schema), and therefore could never have a corresponding row.
139 --
140 -- Post Failure:
141 -- A failure can only occur under two circumstances:
142 -- 1) The primary key is invalid (i.e. a row does not exist for the
143 -- specified primary key values).
144 -- 2) If an object_version_number exists but is NOT the same as the current
145 -- g_old_rec value.

165 -- Description:
166 -- The Lck process has two main functions to perform. Firstly, the row to be
167 -- updated or deleted must be locked. The locking of the row will only be
168 -- successful if the row is not currently locked by another user.
169 -- Secondly, during the locking of the row, the row is selected into
170 -- the g_old_rec data structure which enables the current row values from
171 -- the server to be available to the api.
172 --
173 -- Prerequisites:
174 -- When attempting to call the lock the object version number (if defined)
175 -- is mandatory.
176 --
177 -- In Parameters:
178 -- The arguments to the Lck process are the primary key(s) which uniquely
179 -- identify the row and the object version number of row.
180 --
181 -- Post Success:
182 -- On successful completion of the Lck process the row to be updated or
183 -- deleted will be locked and selected into the global data structure
184 -- g_old_rec.
185 --
186 -- Post Failure:
187 -- The Lck process can fail for three reasons:
188 -- 1) When attempting to lock the row the row could already be locked by
189 -- another user. This will raise the HR_Api.Object_Locked exception.
190 -- 2) The row which is required to be locked doesn't exist in the HR Schema.
191 -- This error is trapped and reported using the message name
192 -- 'HR_7220_INVALID_PRIMARY_KEY'.
193 -- 3) The row although existing in the HR Schema has a different object
194 -- version number than the object version number specified.
195 -- This error is trapped and reported using the message name
196 -- 'HR_7155_OBJECT_INVALID'.
197 --
198 -- Developer Implementation Notes:
199 -- For each primary key and the object version number arguments add a
200 -- call to hr_api.mandatory_arg_error procedure to ensure that these
201 -- argument values are not null.
