java.lang.Object | +--com.ibm.as400.access.AS400JDBCSavepoint
The AS400JDBCSavepoint class is the Toolbox JDBC driver's
representation of a savepoint. A savepoint is a point within the current
transaction that can be referenced from the
Connection.rollback(savepoint)
method.
When a transaction is rolled back to a savepoint, all changes made
after the savepoint was created are undone.
Savepoints can be either named or unnamed. The OS/400 server does not support nnnamed savepoints so internally the Toolbox JDBC driver will create a name to send to the server. The format is T_JDBCINTERNAL_n where 'n' is a counter that is incremented every time an unnamed savepoint is created.
Considerations:
The release after OS/400 V5R1 or later is required to use savepoints. Savepoint support is new in modification 5 of the Toolbox JDBC driver.
