Hi,
Can anyone help me to recover or undo this problem?
I did inadvertently run a command, 'update ..set' without where clause and changed every records. Unfortunately our backup didn't run last night.
Is there any way to recover or undo this? Please help me....

I forgot to add some info:
I am using MySQL 5.0
Table type is MyISAM

You can not undo this operation AFAIK except you have backup.

To my knowledge, there is no way to undo. This should be a lesson learned.
Learn to backup or session your changes (Using BEGIN, ROLLBACK, and COMMIT commands) or just make a habit of dumping the database before logging into it.
Never do it again is the only advice at this point I guess. Sorry it's not much help.

I was able to put them back fortunately!
Yesterday I was so frantic/insane enough unable to remember that I had some tags to identify certain records. Big chunk of records are now back by those tags. Thank god!
In fact we had our departmental on-line backup, which coincidently was not running for last couple of days due to changing backup nod.
Definitely this experience is now valuable lesson to me, not to rely on other backup but to have a habit to backup of my own.
Thank you so much for your replies!
Whew~~~~!

Well, here is some weirdness. First, I noticed that I

I need to update tables in access 97. The table names have spaces (not my

Greetings,
I'm trying to update an address field with "standard" abbreviations so
that I can do a comparison of various accounts to one another on the

tried to stack the update clauses, I seem to get random updates within
the file. All the updates are correct, but they're incomplete. Not
sure how this needs to be done, I added a TOP statement but that
didn't work. ...
