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?”
You need complete backup to rollback your changes. If you do not have complete backup you can not revert back. Sorry.
To restore the database to previous stage if you have full backup:
1) Restore the full backup
2) Restore the latest differential backup.
3) Restore the second most latest (latest – 1) transaction back. Now restore the log to the point step by step.

I want to get all ur interview question. Could I get it in one book. Could u please tell me where to buy these all interview questions books.
I have added tables to the NOTHWIND database. In the past, when I wanted to update NORTHWIND on a new computer to contain the additional tables, I would do the following in SQL Server 2000:
1)I would go to my development computer, that contains NORTHWIND with the additional files, and perform a backup to the disk file myfirstback using the enterprise manager.
2) on the new computer I perform a backup to the disk file myfirstbackup.
3) I overwrite myfirstbackup on the new computer with myfirstbackup from my development computer.
4) I perform a restore on the new computer. NORTHWIND database then contains the added tables.
Please assist me in that SQL SERVER 2005 is not permitting me to use the SQL SERVER 2000 back up file named myfirstback to restore. I created the disk file myfirstbackup while in SQL 2005, overwrite the file with the SQL 2000 version of myfirstbackup and then attempt the restore. SQL 2005 does not permit the operation as I did while in SQL 2000.
What would I do to recover a database if a backup had not been made for 3 months (no transaction logs in that time either, only my current _log.ldf file)? Is this out of the question or could my current log hold the info to restore back from 3 months ago? (It says it’s 120 MB).
Love you blog, I’ve learned a lot.

hi pinaldave ,
May I Help me for this question :
when i use this command :
RESTORE DATABASE Anbartechnical
FROM DISK = ‘D:anb1222.bak’
Sqlserver 2k5 told me :
RESTORE cannot process database ‘Anbartechnical’
because it is in use by this session. It is
recommended that the master database be used
when performing this operation.

i need help restoring my db.
accidently i deleted 2 tables. immediately i did take full backup and log backup. but i couldn’t retrieve my lost tables. unfortunate i have 3 days old full backup and no log backup. is it possible to retrieve my lost table?
10:30 – deleted 2 tables
10.31 – took full backup
10.33 – took log backup
i guess i did blunder!
Thanks in advance
u can get deleted table by restoring 3 days old back up.but the work that perform on these three days is not get. if u restore backup with “10.31 – took full backup ” back up u cannot get the deleted table.
there is no any way to get both last 3 days work and deleted table.
You can get the tables in 3 days old status from 3 days old backup.
If after dropping the tables, you would have taken the transaction log backup first then you would be able to completely recover the tables but by taking the full backup lost the log as well as the possibility to recover later than 3 days old status.
I want to take regular backup of my database that shows along with it month, date & time using stored procedure.
I have written following sql command for that purpose :
DECLARE @str nvarchar(10), @sql NVARCHAR(1024)
SET @sql = N’select @str=Left(CONVERT(VARCHAR(20), GETDATE(), 101),2)+substring(convert(varchar(10),getdate(),101),4,2)+substring(convert(varchar(20),getdate(),108),1,(patindex(”%:%”,convert(varchar(20),getdate(),108))-1))+substring(convert(varchar(20),getdate(),108),(patindex(”%:%”,convert(varchar(20),getdate(),108))+1),2)’
EXEC sp_executesql @query = @sql,@params = N’@str nvarchar(10) OUTPUT’, @str = @str OUTPUT
BACKUP DATABASE [MyDatabaseName] TO DISK = N ‘E:\data\backup\Cmpl’ + @str + ‘.bak’
Then the command returns error near the ‘+’ sign. That is it does not concat the path and string.
Please resolve the error.
