Using Optimistic Locking, both Transaction 1 and Transaction 2 have read the same row including the RID_BIT and ROW CHANGE TOKEN values. Transaction 1 updates the row after ensuring that the row has not changed after the previous SELECT by adding a RID_BIT and ROW CHANGE TOKEN predicate to the UPDATE statement. Transaction 2 now tries to update that same row using the same predicate as transaction 1. What will be the result?

• A.  The row will not be found because the value of the ROW CHANGE TOKEN has changed in regard to the UPDATE of transaction 1. Transaction 2 will complete with an insert of a new row.
• B.  The row will be found with the same ROW CHANGE TOKEN. Transaction 2 will now insert its values replacing those of transaction 1.
• C.  The row will be found with a different ROW CHANGE TOKEN and Transaction 2 will overwrite the values set in transaction 1.
• D.  The row will not be found because the value of the ROW CHANGE TOKEN has changed in regard to the UPDATE of transaction 1. Transaction 2 has to retry in order to retrieve the current data.
