34 -- Description:
35 -- This function will return the current g_api_dml private global
36 -- boolean status.
37 -- The g_api_dml status determines if at the time of the function
38 -- being executed if a dml statement (i.e. INSERT, UPDATE or DELETE)
39 -- is being issued from within an api.
40 -- If the status is TRUE then a dml statement is being issued from
41 -- within this entity api.
42 -- This function is primarily to support database triggers which
43 -- need to maintain the object_version_number for non-supported
44 -- dml statements (i.e. dml statement issued outside of the api layer).
45 --
46 -- Pre Conditions:
47 -- None.
48 --
49 -- In Parameters:
50 -- None.
51 --
52 -- Post Success:
53 -- Processing continues.
54 -- If the function returns a TRUE value then, dml is being executed from
55 -- within this api.
56 --
57 -- Post Failure:
58 -- None.

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

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

170 -- Description:
171 -- The Lck process has two main functions to perform. Firstly, the row to be
172 -- updated or deleted must be locked. The locking of the row will only be
173 -- successful if the row is not currently locked by another user.
174 -- Secondly, during the locking of the row, the row is selected into
175 -- the g_old_rec data structure which enables the current row values from the
176 -- server to be available to the api.
177 --
178 -- Pre Conditions:
179 -- When attempting to call the lock the object version number (if defined)
180 -- is mandatory.
181 --
182 -- In Parameters:
183 -- The arguments to the Lck process are the primary key(s) which uniquely
184 -- identify the row and the object version number of row.
185 --
186 -- Post Success:
187 -- On successful completion of the Lck process the row to be updated or
188 -- deleted will be locked and selected into the global data structure
189 -- g_old_rec.
190 --
191 -- Post Failure:
192 -- The Lck process can fail for three reasons:
193 -- 1) When attempting to lock the row the row could already be locked by
194 -- another user. This will raise the HR_Api.Object_Locked exception.
195 -- 2) The row which is required to be locked doesn't exist in the HR Schema.
196 -- This error is trapped and reported using the message name
197 -- 'HR_7220_INVALID_PRIMARY_KEY'.
198 -- 3) The row although existing in the HR Schema has a different object
199 -- version number than the object version number specified.
200 -- This error is trapped and reported using the message name
201 -- 'HR_7155_OBJECT_INVALID'.
202 --
203 -- Developer Implementation Notes:
204 -- For each primary key and the object version number arguments add a
205 -- call to hr_api.mandatory_arg_error procedure to ensure that these
206 -- argument values are not null.
