SAVEPOINT statement to create a name for a system change number (SCN), to which you can later roll back.
Oracle Database Concepts for information on savepoints.
ROLLBACK for information on rolling back transactions
SET TRANSACTION for information on setting characteristics of the current transaction
Specify the name of the savepoint to be created.
Savepoint names must be distinct within a given transaction. If you create a second savepoint with the same identifier as an earlier savepoint, then the earlier savepoint is erased. After a savepoint has been created, you can either continue processing, commit your work, roll back the entire transaction, or roll back to the savepoint.
Creating Savepoints: Example
To update the salary for
Greene in the sample table
hr.employees, check that the total department salary does not exceed 314,000, then reenter the salary for
UPDATE employees SET salary = 7000 WHERE last_name = 'Banda'; SAVEPOINT banda_sal; UPDATE employees SET salary = 12000 WHERE last_name = 'Greene'; SAVEPOINT greene_sal; SELECT SUM(salary) FROM employees; ROLLBACK TO SAVEPOINT banda_sal; UPDATE employees SET salary = 11000 WHERE last_name = 'Greene'; COMMIT;
