Recently i got task from Senior DBA, as : Recover a database without LOG file Currently Data File is available.
Log file is also available, but shows size as 0 KB. Means Log file is corrupted.
Currently existing DB is shown as Offline Mode in SSMS.
So i got below link:
[URL]
When i tried 1st/2nd solution from above link, i got below message:The log cannot be rebuilt because there were open transactions/users when the database was shutdown, no checkpoint occurred to the database, or the database was read-only. This error could occur if the transaction log file was manually deleted or lost due to a hardware or environment failure.
To try that 3rd solution, I had to DELETE/Remove existing DB from SSMS, so i can create New DB with same name.
When i tried to delete Log file from Command Prompt, using below command, Windows replied that File is corrupted, so it cannot be deleted.
DEL /F /Q /A C:Program FilesMicrosoft SQL ServerMSSQL11.SQLEXPRESS2012MSSQLDATAMyDB.ldf
Meanwhile my Senior DBA brought DB in Recovery Pending mode.
So if i want to go for 3rd solution,then i need to DELETE file, But Windows is not allowing me.
I run MSDE on a Windows XP Server and my database was marked as "suspect" by Enterprise Manager and its icon become gray. I detach that database and try to re-attach it but there is an error as the following:
After that, I uninstall the MSDE and re-install new MSDE SP4 and try to re-attach the database file again and there is still an error. Is there anyway i can recover the data from that database?

Our SQL database log file got physically deleted. Now the database is in suspect mode. Is it possible to recover / restore the database just with the data file.
SQL server. By-mistake I updated values of a column in a database hosted online, is there any way undo the transaction. I didn't created any backup of the database. I read that still it can be recoverd through the .ldf (log file) but unable to access it. Is there anyway to get access of the Log file or is there any way to recover the data.
I have SQL server 2000 which recently crashed. I try to recover it andfound out that the Master database is corrupt. I never backup myserver using inline sql backup nor any third party backup program thataware to SQL server. But I have full system backup of volume c on tape(using NTBackup), which includes old version of Master database. Myquestions are:1. How can I recover this file into SQL server?2. If so, it is not risky to recover Master database from two weeksago?Thanks in advance!
what type of replication is best and easiest to startup on the DR site in event of a failover for an SQL server with very high transaction occurring on the database.I normally handle Oracle database and we use SAN to SAN replication to the DR site, all w have to do is mount the replicated disks at the DR site and Startup the database.How do i achieve this on SQL database including having the using logging details work at the DR site.
Recently, one of our database's mdf and ldf was corrupted. We were able tobring back the database with the capability of importing and querying thedata. However, the data is not the full list. Some of the data are stillmissing because the tables we want still has sone 'chain mis linkage' errorwhen we did a DBCC checkdb/checktable. DBCC couldn't fix those errorseither. We're pretty sure that there are some data still burry under thecorruption. Then we thought of the life LDF file. This file should haverecorded every transaction up to the point of failure. So we trying torecover that file, but there are 2 problems. First is we don't have back upof that file and 2nd, that file is also corrupted. I couldn't backup thecorrupted ldf file at its current state. It's giving me some unrelated errormessage like disk space is out. All I know now is the only hope to recoverthose missing data are in this LDF file. We tried to use this software fromLimingent Log Explorer to recover it. So far no such luck with that. SoI'm asking anyone who has similar experience or problem. Please let me know.I need to know anyway to recover this LDF file, either by using sql server'snative tools or 3rd party tools. Any input is helpfull. thanks in advance.Wei
Hopefully someone can help me with the following (potentially huge) problem:
We've got a simple database application running on microsoft sql desktop engine. This database contains two tables. Up until now all worked fine, but probably due to a programma that crashed part of the database seems to be corrupted or broken while today only one table contains/returns data and the other table does not return any values!
When I open the .ldf and .mdf files in notepad I see that there is data belonging to both the tables. But how do I recover it??
The max. size of the database has not been reached by far (it's only 9Mbs), the sql queries are correct.
This .ldf file is a log file (?) I can't find detailed info about the principles of these .ldf and .mdf files on the internet, is it possible to trace back what has happened en recover the database that way?

My database corrupted because when I was running an update query, there is a power failure. After the computer booted, I cannot open the database anymore, it just not responding. Then I stop the sql server service, and tried to rename the .mdf and .ldf. After that it worked normally, but I need the data from the corrupted mdf file, I tried to attach the database but it just hanged. I even tried to attach without the .ldf file but it didn't work either, so I concluded that the problem is with the mdf file.
Last week I backed up my SQL Server by using BE 2012. I named the file "SQL Server BAK" which contained copies of my SQL Server databases. A few days ago I lost some part of my data due to accidental deletion. I backed it up, so I tried to restore the database from the .bkf file. The problem comes here, when I try to to restore my .bkf file, it becomes inaccessible.what causes this?

It's very Urgent,I am not expert in SQL Server 2000.
Our MSSQL 2000 server crashed yesterday and one database cannot be restored. the latest backup we have is june. We can only recover the MDF file from the harddisk and according to our admin, it cannot be restored anymore because no proper shutdown was made.

I am trying to restore a database called BCC_DB (I'm actually just needing one table opened to find some data in one column) so I created a blank database called BCCrestore.
I have a .bak file called BCC_DB_backup_201505020017.bak.
I placed it in my local drive C:BCC_DB_backup_201505020017.bak and tried the SQL:
RESTORE DATABASE BCCrestore FROM DISK = 'C:BCC_DB_backup_201505020017.bak' GO
I get an error:
Msg 3201, Level 16, State 2, Line 1 Cannot open backup device 'C:BCC_DB_backup_201505020017.bak'. Operating system error 2(The system cannot find the file specified.). Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally.
How do I begin? I had previously installed the SQL Server 7.0 with NT Authentication and everything was fine until I Rename domain Name and Computer name. I decided to uninstall SQL Server, and then reinstall it. From this action unable to see my database in enterprise manager. I Rename old domain and computer name again. and reinstall with Upgrade Version. but still same effect. Can anyone help? What do I need to do to get my database to work again? Any input on this will be appreciated. Thanks in advance.

Thanks a lot
P.S.- I also have whole of the earlier MSSQL folder present in the earlier program files backed up.Would that help in anyway.
I've had a powerfailure, that resulted in I had to scratch my DB server, I've managed to get all the .mdf and .ldf files from the server. On the new server I get a "Error 823: I/O error (torn page)" when I'm trying to attach the .mdf file to the New server. Both the new and the old server is a win2003 with SQL 2000 SP3
Is there anybody who knows how I can recover the DB?
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.
Greetings, I have just arrived back into the country (NZ) and back into ASP.NET. I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page. Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer. Cheers ~ J
I have a mirred database and have snapshot created from the mirroed database. I can do data selecting from the snapshot.

finding the database size from the backup file.I have SQL 2012 backup file, is there any way to find the estimated database size from the backup.I tried restoring , i got an error saying " no space need additional xxx bytes " ...does this error gives the exact space needed to restore ?
One more question....one of the backup file size is 7.2 GB, when i try to restore it ....it throws error saying it needs 292GB extra space while only 100 Gb is available. How come 392 Gb sized database becomes 7.2 Gb .bak file ?

I have a production database which uses merge and snapshot replication. The Merge is for 3 tables. The snapshot is to update the rest of the data once daily. I use a Full recovery model and perform database backups (full, differential) and transaction log backups.
I have a database optimization plan which runs 4 times a week. This plan performs and integrity check and rebuilds the indexes. This optimization plan is growing the transaction log by about 8MB each time it is run and we are running out of space on the drive for our log files. The space is not being reused.
I saw in another post where Gail Shaw suggesting using SELECT name, log_reuse_wait_desc FROM master.sys.databases to see why the log space is not being reused. On the database in question, the above returns "REPLICATION".
A colleague tried to backup the transaction log a couple of times to truncate the log this weekend. She was going to perform a DBCC Shrinkfile command afterwards. But the truncate failed. Again looking into things it seems replication prevented the truncation.
We are looking at stopping the merge replication or even removing it to truncate the log file and then recreate the merge replication. How to handle shrinking the log file for now and then seeing if there are any checks or changes I can perform which will allow the transaction log space to be reused.
I need to create a new db from a backup file of an allready existing database (vehicledb) on this server.So i created a new database with name "vehicledb2" .But when i try this, the backup says that this file is used...The backup set holds a backup of a database other than the existing 'Vehicles2' database. Restore of database 'Vehicledb' failed.
I have accidentally taken the backup of a database twice into same .bak file. Now the file is twice the size. Will it be fine if I restore this backup? Or will I screw up any data?
