उत्तर

The SAVEPOINT command is used to temporarily save a transaction so that you can roll back to the point whenever required. The different states of our table can be saved at any time using different names and the rollback to that state can be done using the ROLLBACK command.
SAVEPOINT savepoint_name;
UPDATE Student SET Name = ‘Mini ’ WHERE Admno = 105;
SAVEPOINT A;
