go

insert into a (b) values (1), (2), (3)

select * from a

begin tran

truncate table a

select * from a

rollback tran

select * from a

drop table a

This would ideally give you an exception at the insert statement. Because as far I know the comma seperated value insertion as mentioned in the above insert statement is incorrect. So answer should be an exception/error
