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

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

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

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