Hi all
I'm a newbie with SQl Server But somewhere i read that SQL server Data can be Recovered through *.LDF files
now i want to know if i open a table in Enterprise-Manager and delete some records through DELETE statement or
manually, is it possible to recover those deleted records or not? if so how?
Thanks in advance.
Regards.
I have an sql 6.5 server that has had it OS (nt4.0) reinstalled on c:.
sql was installed on d: and all of the dat files are still there, i need to recover data from one of these, i tried install on a new machine and creating a device/db with same name and then over writing the file with the old one but enterprise manager shows it as suspect and will not let me work on it.
Any assistance would be appreciated.

Hi,
Bit of a panic here.. Someone accidentally deleted a database device (and
consequentially the associated databases) from MS Sequel 6.5. I don't have a
backup dump of the databases.
Does anyone know how I restore the device? I have the DAT file and I can
see the data in it if I use a text editor.
Thanks

Is there any way to get the deleted records from LDF or MDF file. Today by accidentally I executed one query and that dropped my table Inbox(table name only) from database. And in that table there was more 4,000 records, all these lost. So anybody can help me how to recover this table records?. Is there any way to get these?
I don't have any backup for this table.

A friend of mine called and said that his database was suspect and he detached it and was unable to attach it. The SQL Server Version is 2000 with the latest service packs installed. When I checked it the database (MDF) size was 1MB and the LDF size was 3.8 GB. I was not able to attach the two together and I was not able to attach the database using sp_attach_single_file_db. I did find an old backup of his database and attached that so he can work off of it but it is 1 yr old and he needs recent data. Since the MDF seemed to be blank we cant do much with that, but there seems to be data in the LDF. Is it possible to extract any data from the LDF file?

Hi!
Is it possible to generate a script, that extracts every bit of data it can, from tables which suffers from latch errors;
DBCC CHECKDB ->
Msg 7985, Level 16, State 2, Line 1
System table pre-checks: Object ID 4. Could not read and latch page (1:403) with latch type SH. Check statement terminated due to unrepairable error.
So bad news on that one. There are no backup available that I know off, so all bets are off on that part of the recovery process.
The "good news" part of the problem, is that it is possible to extract some data out of the table, before SQL server 2005 returns the error. So what I want to do, is get every bit out I can, doing it somehow automatically, so I don't have to run bcp on 180 tables :).
Presumeably, this is quite possible, but how?
NB. If I do a complete basic SELECT * FROM tbl1, it returns data, then errors out, but what about the data after the last row SELECT returns? Is it possible, that there might be data in the table that are recoverable after the 'broken row(s)'?
I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

Can anyone give me assistance on trying to restore my master file. I purposely corrupted my dabase on my test box so that I could work on my recovery process. However, during one of the steps I used the:
restore database Master From
disk= 'c:mssql7ackupmaster.bak'
Command. However, I continue to recieve:
Server:Msg3201, Level 16, State 2, Line 1
'Cannont open backup device 'c:mssql7ackupmaster.bak. Device error or device off-line. See the SQL Server error log for more details.
Note I am in single user mode and I have not been able to find anything specific in the error log file.
Can some tell me what possible could be the problem. Thanks.
Any ideas on how long it should take SQL Server 6.5 running on a 8 Gig RAID 0 array to "recover" a 4 GIG database. I rebooted the machine this morning (seldom ever have any problems with it) and it seems to be taking an awfully long time (15 min so far). I'll let you know what happens in any case.
View 2 Replies View Relatedis it possible to recover an existing SQL server? Here is what happened. WNT server 4.0 was corrupted, had no backup, repair did not work. consequently, i had to reformat the C drive and do a clean install of the OS.
my SQL files and user databases were on other drives. can i do a install of SQL server and tell is were the SQL server files (ie., the MSSQLDatamaster.db) are and have it use those files? given that this problem occurred as i tried to backup my SQL server database.
hope you can help or my butt is burned!
We are having major hardware replaced on our W2000 Adv Server and we
need to be prepared to restore the entire system.
If the hardware fix goes badly, worst case, the plan is to
rebuild the server and then REINSTALL SS7 and
then restore all the databases from tape backups.
My question is, which database(s) should we restore first?
Should we restore master and then proceed to restore the user
databases or restore the user databases first and restore master last?
Thank you in advance.
Help !!!!
How would you fix these two problems.
1. On the window of Enterprise Manger and under the databases, the database shows one of the databases like this manag_dat(recovering)rather than manag_dat. (manag_dat is the name of the database). What could cause the probem and how to fix it?
2. Same position as above, but instead it shows manag_dat (loading). I tried to delete its device and the database. it hang. How would it happen and how to fix it?
Thank you ahead of time
I need to recover a database, but unfortunatelly i donīt have any backup... Well, it was not my fault. Anyway, i only have the physical .DAT files of the data and log devices of the database.
Will it work if I create two devices with the same name as the old devices, create a database with the same name as the old database within these devices and then run a full script of my old database, then change the 'phy_name' on the sysdevices to point to where my old dats were, or replacing the current ones with the old ones? If not, will anything else work?
Thanks in advance.
My server crashed i had full back up my .BAK file for every database and i reinstalled a fresh verion of sql server 2000 enterprise and when i comme in enterprise manger to restor the master its telling me i need to be in single user mode what do i do.
View 2 Replies View RelatedAny ideas how I can recover a job that has been deleted (?) from SQL7.0 ? We had one which was used on a regular basis which has nowceased to exists. I've spoken to the people responsible for the serverand was met by blank faces (as usual). They have no idea when it wasdeleted, by whom or when. To make matters worse, they don't think theycan get it off the backup set without a major bit of work to theserver. Suprisingly, none of the users noticed that things had stoppedworking.Unfortunately, I needed to do some work on this in preparation for mymonthly meeting with my boss on Monday. Whilst I'm not to blame, I'dlike to understand a little more about any options available to us forrecovery as he will undoubtedly ask when he finds out.I have an old back up on another server, so it's not the end of theworld re-creating it, but I was under the impression it was backed upproperly. Is this normal or have they missed something ?Are there any ways I can recover this ? What can I get done to thebackup to make sure this is backed up properly ?Thanks in advance.Ryan

I am working on SQL Server Business Intelligence Development Studio - 2005. While working on the same, the studio got closed automatically and I was not able to save my existing file.
When I try to open the last saved file, it is thowing the following error:
Deserialization failed: The element 'QueryParameter' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition' has incomplete content. List of possible elements expected: 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition:Value ##other:*'. Line 277, position 12.

Now I am not able to open the file. Please let me know how can I recover the lost file.

I saw the other thread that is related, but let me give you our circumstances. A drive failed and that drive had the SQL installation and the *.ldf files on it. The MDF files were unscathed.
The drive has been rebuilt and I have reinstalled SQL 2000 SP3A on there (that is what was there before). I have tried attaching the MDF through the GUI and letting it create the log for me. This failed.
I tried sp_attach_single_file_db, but this failed since the db was never dettached.
I tried creating the db again, dettaching it, copying the old (good) MDF file over the newly created one and then attaching (using multiple attach approaches). It knows that the log file and mdf are not matched and won't let me do the attach.
I also found DBCC REBUILD_LOG, but the article in SQL Mag supposes that your instance is still in working order and that there is an entry for the db in sysdatabases. Such is not true in my case.
Can you help? We are trying to get old backup tapes shipped to the site, looking up our Gold Partner contact info, etc., but in the meantime, I am trying to get the data restored even if we lose some transactions.
Thanks for any help!
1) How do I reinstall a fresh copy of the MSDB database (since my current
one is corrupt). Is there any script available?
2) What is the purpose of the MSDB database? Backups and jobs/ Wizards?
Thanks for your help.

Our database -SQL Server 7.0 sp1 (NT 4.0 sp5)- is growing at a very fast rate despite the fact that we are deleting old record. It doesn't seem to be recovering disk space for the deleted records. Please let me know if there is a specific setting that can help us recover disk space. )
View 1 Replies View RelatedI have a 3GB DB that I was running an update script on. The sript failed and ran out of transaction log space. I expanded it and stopped and restarted SQL. The user DB is now marked as recovering. How long should I wait for it to recover? I don't want to have to restore again and start all over with my script. Please help.
(By the way this is a restored DB)
Thanks.

Is there any way to recreate SQL2k cluster recources after someone removed them, which is is quite easy to do in Clustermanager?
We are running testscenarios at the moment with SQL2000Adv on Win2kadv servers. We assume a situation where someone at a client site accidentaly removes one or more of the SQL cluster receources in clustermanager. We can easily re-create the recources manually, but they will not come online. Of course it is always possible to re-install SQL2k on the nodes, but after "accidentaly" removing recources even that seems to be a pain, as the sql2k installer will not uninstall properly or reinstall/overwrite. Usually we get both nodes back up and running after running the uninstaller, cleaning up the registry and reinstalling SQL2k with the previous virtual (sql)server name and all the previous settings.
There must be a more efficient and reliable way to recover from this type of "usererror", but neither technet nor any other site seems to mention anything on a situation like this.
Any thoughts?

I accidentally deleted at SQL 2005 database. Is there any way I can get it back? No, there is no backup.
We occasionally use TruncateTable to delete the contents of a number of tables on our SQL Server 7 database. We then build them anew from an outside source. I am finding that the size of the database (and corresponding backup file) has grown significantly. As I understand it, the space representing the deleted records is retained by the database. I have investigated using various DBCC commands, to no avail. Does anyone have a clue as to how I can recover this lost space? ... Thanking you in advance.

What should I have done? Is there anything that can be done other than restoring from backup?
How does one know if the database is really recovering or is EM just joken? I can wait 2 hours
before starting the restore
I was BCPing 12 million rows into a staging table. II used the '-b' option every 20K which I thought
would do a commit and clear the log in batches. After the process EM appeared to show the transaction log
as empty. Upon inspecting the Bcp output file I discovered the message that the BCP did not complete
because syslogs was full. I could not do a truncate transaction log or a dump database. I tried to
do a truncate transaction with no_log and it appeared to just hang. I stopped the SQL Server thinking
I could dump the transaction log, but could not start the Sql Server again. I then stopped the NT Server
because 'if all else fails'. The SQL Server started but the user database if marked as recovering.
Just upgraded a users computer from 7.0 to 2000. All previous SQL Server Registrations are gone IP Addresses, User Names and Passwords arent readily availiable. Are the old connections stored in a DLL or Ini that I can place in the SQL 2000 folder to regain those or do I need to recreate some DSNs?

We currently have a company program in foxpro which inputs all of our information into its database. We are trying to shift from this to new updated software and a SQL database. There is a program we created which converts all the data from our old database into our new SQL database in preparation for our final move to the newer software. However, some of the tables in SQL were not taken directly from our old database but rather added in directly after our initial use of SQL, so when we ran our conversion software, a couple of specific tables were wiped because there was no equivilant within our old database. We already altered our conversion program to not touch those tables again, but is there any way to do a roll back or to find a backup of specific tables?
View 4 Replies View RelatedI'm having some deadlocking issues in my ASP.Net 2.0 web application with SQL Server 2000. One solution I've come across involves catching the the deadlock error (at the application level) and then retrying the query again, in the hopes that whatever was causing the deadlock is no longer locked.
I've tried to implement such a solution, where I catch the deadlock exception, then try to execute the same query again. Only now I'm getting a "The transaction is in doubt" exception.
So am I going about this wrong? Am I supposed to retry the entire transaction, or is valid to just try to redo the one query that it failed on? Is there some way around the transaction being in doubt?
