问题 I want to know if there is a way to revover the state of a database at a certain date. Unfortunately I don't have a backup. 回答1: Without backups of any kind, there is nothing you can do - since previous state has been wiped away by checkpoints (even in full recovery, it acts like simple recovery until you've bothered to take a backup). This situation is precisely what backups are for. If you jump out of a plane without a parachute, don't bother looking for the ripcord... 回答2: As Aaron said

问题 My firm was delivered a 20+ GB .sql file in reponse to a request for data from the gov't. I don't have many options for getting the data in a different format, so I need options for how to import it in a reasonable amount of time. I'm running it on a high end server (Win 2008 64bit, MySQL 5.1) using Navicat's batch execution tool. It's been running for 14 hours and shows no signs of being near completion.

When I run following statement on SS Management Studio; EXEC('RESTORE FILELISTONLY FROM DISK = ''C:\backup.bak''') I get a result set in a grid and also I can use INSERT INTO <temp_table> EXEC('RESTORE FILELISTONLY FROM DISK = ''C:\backup.bak''') to populate a temp table.
