box.rollback()

box.rollback()¶

End the transaction, but cancel all its data-change operations. An explicit call to functions outside box.space that always yield, such as fiber.sleep() or fiber.yield(), will have the same effect.

Example

-- Insert test data -- box.space.bands:insert { 1, 'Roxette', 1986 } box.space.bands:insert { 2, 'Scorpions', 1965 } box.space.bands:insert { 3, 'Ace of Base', 1987 } -- Rollback the transaction -- box.begin() box.space.bands:insert { 4, 'The Beatles', 1960 } box.space.bands:replace { 1, 'Pink Floyd', 1965 } box.rollback()
