I'm afraid you will have to execute the SQL statement undoing it. Of you don't know the previous values, you're out of luck.
Then a backup is your best friend.

Hi friends
I was given a query to update the record in table A with where clause. But I executed it in production mistakenly without where clause so it updated incorrectly for all rows.
How do I resolve this?
