- All Implemented Interfaces:
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:
SQL 2003 standard does not support unnamed savepoints. However, this feature is supported from version 2.0.
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
