The savepoint statement declares a savepoint within a multi-query transaction (MQT). Savepoints are used in conjunction with the abort statement. Abort allows you to specify a savepoint. An abort to that savepoint undoes all updates performed between the savepoint and the abort statement. Savepoint_name must be a valid, unquoted object name. Declaring a savepoint closes any open cursors.

There is no limit to the number of savepoints that you can declare within an MQT. You can use the same savepoint_name more than once. However, only the most recently declared use of a savepoint_name is active within the MQT. In other words, if you abort to a savepoint whose name is used more than once, the transaction is backed out to the most recent use of the savepoint_name.

All savepoints within a transaction are rendered inactive when the transaction is terminated (either committed with end transaction, or aborted with abort or by the system as the result of deadlock or timeout).
