Обсуждение: rollback question...
how many levels of rollbacks can postgres handle? Is it set to only rollback changes for the last transaction done on a database, or can you specify how many transactions to rollback to. lorenzo _________________________________________________________ DO YOU YAHOO!?

Only the current transaction can be rolled back. Lorenzo Huerta wrote: > how many levels of rollbacks can postgres handle?

I think there is confusion here.... every statement between the "begin work;" and the "rollback;" are rolled back... not just one.... If you have not defined where to begin, you cannot roll back... it's not a case of being able to back out individual commands one by one....
