Class jdbcSavepoint

public class jdbcSavepoint extends Object implements Savepoint

The representation of a savepoint, which is a point within the current transaction that can be referenced from the 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.

HSQLDB-Specific Information:

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
