Description of the illustration savepoint.gif

Semantics

savepoint

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.

Example

Creating Savepoints: Example To update the salary for Banda and Greene in the sample table hr.employees, check that the total department salary does not exceed 314,000, then reenter the salary for Greene:

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;
