public class jdbcSavepoint extends Object implements Savepoint
Connection.rollback
method. When a transaction
is rolled back to a savepoint all changes made after that
savepoint are undone.
Savepoints can be either named or unnamed. Unnamed savepoints are identified by an ID generated by the underlying data source.
As the SQL 2003 standard does not provide for unnamed savepoints, this feature is not supported.
If the connection is autoCommit, setting savepoints has no effect as any such savepoint is cleared upon the execution of the first transactional statement.
Since: JDK 1.4, HSQLDB 1.7.2
