SQL SERVER - Restore Database Without or With Backup - Everything Abou

The questions I received in last two weeks: “I do not have backup, is it possible to restore database to previous state?” “How can restore the database without using backup file?” “I accidentally deleted tables in my database, how can I revert back?” “How to revert the changes, I have only logs but no complete backup?” “How to rollback the database changes, my backup file is corrupted?” Answer: You need complete backup to rollback your changes. If you do not have complete backup you can not revert back. Sorry.
