rollback

The rollback() operator aborts an active transaction.

Synopsis

rollback();

Summary

Allows the user to abort the transaction, rolling back all queries up to this point in the transaction. All resources held by the transaction will be released.

AFL% rollback(); Transaction rollback successful

Invoking rollback() outside of a transaction is an error.

When the user disconnects (legacy client API) or the user session expires (HTTP API) an implicit system rollback() occurs.

[TBD An administrator should be permitted to rollback a transaction using the cancel operator]
