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

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

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

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