Tables Emptied And No Logs To Recover Them!
Aug 6, 2007
Greetings,
I got severe data corruption issue today when I copied a SQLServer2000 database from our remote server to my local PC through enterprise manager. The new copy on my local PC did not have any records in the user tables, and when I looked at the remote server, the records gone either with only table skeletons and procedures there. The mdf file on the remote server is emptied at all, but that on my local PC still has 50MB. I think there are data in this file, but the ldf log was also emptied, but I cannot recover it -- I do not have backup and the ldf file was also emptied.
I ran checkdb, and it did not tell any error but show that all the user defines tables has zero records.
I wonder whether there is now any way to recover the data. They are important and I really dont want to lose them.
Thanks in advance!

A mistake was made and "old" transaction logs (and old backups) weredeleted. It appears that a long living transaction was living in one ofthose logs. Now the EP shows (no items). The DBs themselves are stillfunctioning OK, just the EP shell that's not working.What's the proper resolution?Thank you in advance,FBCK

Good day. I am a non-programmer but one tasked to "check" on the recent error in our company's systems.
In summary, most, if not all Tables were deleted from the different databases. Add to that, the logs prior to the event were also lost or deleted. Yes we do have back ups but restoring wasn't that simple. Another domain server was corrupted causing further delays in the restoration.
This is the second time it has happened and the events were 31 days apart. We would like to identify the causes for our preventive actions. Is there a hardware/software problem that may have caused these? Of course, we would like to rule out that it was done intentionally... but if you guys think otherwise, i'd like to further ask how we can validate the theory.
Thank you very much...

I have a Db that is 1.7 gigs. The table data takes approximately 200megs. The transaction logs were truncated. Where else can this large size be coming from and how can I confirm?
DB is generally small. ~25 tables, 100 SPs, 10 views, etc.
Note:
I have 4 queues using SQL Notifications, but when selecting from them results in no data.
Thanks
Scott

Hi,
In my case I have to log the errors raised by any task in a package to either windows event log, text file or SQL server. Also I need to send an email notifications to a group of people telling them about the error.
Now can I use SSIS package logging for logging the errors into the required destinations. I mean right clicking on the package and selecting Logging, then adding the required log providers and enabling the events for logging into those. I think I have to upfront select the log providers to log the error, I will not have the liberty to log the error to the destination, the name of which is passed as a variable to the package. This is okay with me though.
Now what will a custom log provider help me to do in this case. Also can I somehow configure my package to call the send mail task everytime an error is raised.
Also, one more option can be developing a package that only does the error handling. It will take in the paramters or the error codes and descriptions, the destination to write to and a flag to send mail or not for that particular type of error.
What do you think? Kindly advise.
Thanks in advance for your help and time.
Regards,
$wapnil

When looking at SQL Server error logs, I noticed that the current error
log had grown to 1MB whereas most of the files are only a few KB.
QUESTION 1: Can I set the max size for an error log file? If so, how?
QUESTION 2: If not, is there a workaround?
Thanks

Hello,
Is it possible to restore a SQL 2000 database with data from a transaction log?
I am not sure what happened to my database, all the data in the tables is gone. I generated a db script to create a duplicate database. I saved the .sql file on my local machine, separate from the db server, renamed the database name in the .sql file to a new database. Tested script in query analyzer for syntax, all was fine. Running it at this point would have created a new database with a different name, right?
Now my original database is empty. Can someone please provide me with information on getting my data back. Is there a way of using the transaction log to recover the data.
Thanks

Paul,
Having read your useful insight into the sorts of issues around the corruptions that folk have posted in this forum I'm interested in preparing for the day when one of our servers gets corrupted :-(
Should I expect to be able to:
Restore FULL backup from Before the corruption first happened
Restore all Tranaction log backups since
and would get me back to ground zero?
I'm thinking:
if I do a DBCC CHECKDB once a week, say, immediately after a FULL backup - then if that gives me some error messages I've got last weeks Full backup and a weeks worth of Trans Log Backups to restore - which is OK for a rare disaster.
I apprecaite that the thing that caused the corruption might be a memory or disk fault, which might also have broken the creation of the backup files too - in which case I'm fairly stuffed!
Does a RESTORE do a checksum of somesort that would detect a corruption caused by, say, a memory fault or a disk controller that wrote the block faultily [twiddled some bits, but did not report error]?
In which case continuous restores of backup files to A.N.Other server would discover the moment at which a backup was "known bad"
Am I close?
Thanks
Kristen

OS: Windows 2003 Standard Edition
MS SQL: Standard Server 2005
I am looking to implement a disaster recovery plan for an MS SQL 2005 server, this is what I have done so far but would like the benefit of your experience to provide feedback and help improve the strategy.
MS SQL Server:
I have two maintenance plans, one to backup the system databases to individual backup files (.bak) and one to backup all the user databases to a backup device (mssql_backup) The backup files & device are in a directory (backup) and is backed up using NFS. I keep a copy of the backups on a USB HD which is stored offsite.
Disaster:
Office burnt down
Recovery:
New server, install OS/MSSQL, patch up to same version as burnt server.
Copy .bak files to new server, copy mssql_backup file to same location as previously held i.e. X:ackupmssql_backup
Start MS SQL in single user mode, restore master database using .bak.
Start MS SQL in normal mode, restore other system databases using .bak
Restore user databases using mssql_backup device
Testing:
Using the above steps I was able to restore up to the point of "user databases" Getting to this point I realised that there are a number of databases to restore, in my novice ways this seems to be a lot of right-clicking and restoring.
1) is there a command that would in effect be able to restore all databases using the backup device?
2) do I have a working version of the databases to the point of the last backup? Or am I missing something?
3) in my current setup in mind (SQL backup to NFS directory and picked up my backup software) is there a 'better' way I could be doing this which would make the restoration procedure more efficient
