rollback_to_savepoint
(savepoint) Do not end the transaction, but cancel all its data-change and box.savepoint() operations that were done after the specified savepoint.
Return: error if the savepoint cannot be set in absence of active transaction. Possible errors: error if the savepoint does not exist.
Example:
function f() box.begin() -- start transaction box.space.t:insert{1} -- this will not be rolled back local s = box.savepoint() box.space.t:insert{2} -- this will be rolled back box.rollback_to_savepoint(s) box.commit() -- end transaction end
