## Class JDBCSavepoint

- java.lang.Object
- - org.hsqldb.jdbc.JDBCSavepoint

- All Implemented Interfaces:
    java.sql.Savepoint

      public class JDBCSavepoint
      extends java.lang.Object
      implements java.sql.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
