Will crashed transaction be rollbacked?

Hi All,

If the system crashes while a transaction still in progress, what will happen to it in recovery? Will it be rollbacked? For example, if I insert a row and the insertion has been xlogged, then the system crashes before this transaction commits, will this insertion be cancelled in recovery?

Thanks,
Jialun Zhang

The transaction will be rolled back if it hasn't committed.

Thanks,
