  org.hsqldb.jdbc.jdbcSavepoint

All Implemented Interfaces:

Savepoint

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 SQL draft standards do not provide for unnamed savepoints, this feature is not supported in 1.7.2.

Named Savepoints can be set if the Connection is autoCommit. Such Savepoints will be cleared when the next statement is issued unless autoCommit is set to false prior to executing any statement.

Since:

JDK 1.4, HSQLDB 1.7.2
