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 am working on SQL Server 2008 R2 and unfortunately I have lost my .mdf file after detaching it from my database, but the .ldf is still in my system. Is there a way to recover my database from .ldf file?
View 3 Replies View RelatedRecently 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 have SQL server 2000 which recently crashed. I try to recover it andfound out that the Master database is corrupt.

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!

Database File Placement Layout? We are planning to implement a new SQL Server 2014 OLTP Database with a 1 TB Data file and 1 TB Log File. I am looking at the possible layout of the database files and trying to determine the best possible configuration. My knowledge/research tells me that items which need separate storage due to constant simultaneous access are:
Data files – should go on the fastest reading storage.
Log files – should go on the fastest writing storage.
TempDb – involves a lot of writing at the same time the data files are being read.
Indexes - (including full text indexes) - involves a lot of writing at the same time the data files are being read.
Also, are there any benefit to having multiple OLTP Database Log files? Because SQL Server writes to the log file sequentially, I do not see any advantages to having multiple database log files. In a SQL Server 2012 Class I took last summer, under “Determining File Placement and Number of Files”, it states “Use a single log file in most situations as log files are written sequentially.”
I have installed SQL 2014 (Evaluation Version) on testing machine. We want to import some excel files on database. I manually created one Test Database and now trying to import excel file.

View 3 Replies View RelatedHi,
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.
Is there any way to recover my data ??
Thanks in advance

One of the database in our SQL Server 2000 environment is in the suspect status. We need to bring it back to the normal status.
The problem occurred because the disk on which the data file and log file for this database were placed ran out of space.
Pls note other databases in the same server are working fine.
Later on more space was made available on this disk. We tried the following options but with no success.
1. Reset the status of database and restarted the SQL Server. After restarting the SQL Server, the database once again was showing the suspect status.
2. Used the same data and log file in another SQL Server and attached with the database in this another SQL Server.
3. Tried dbcc chkdb with repair_allow_data_loss.
Since the database is in suspect status, we are neither able to export the data nor able to back up the database.
Please suggest some options to recover the database from the suspect status. Also it would be great if we can get the commands, scripts to find if the data/log file is corrupt and a way to correct it (even with data loss is fine).
I know that there was huge tempdb usage and may be the disk was full but SQL server is not suppose to restart in this case.What could be the reason behind this? SQL server restarted and is currently up and running.We are using SQL server 2008 SP3
View 10 Replies View RelatedMy Client Accidently Deleted Somes Rows From Database Now. Now We are Struggling For Almost 2 Days To Get Them Backup. I Even Checked LDF File From Notepad It Have Those Rows But Not Formatted. (Some Similar Text From Some Column Which Got Deleted.)And The Database has no Backup which i Go to Task -> Restore...Server is Running on Sql Server 2008.
View 7 Replies View RelatedAs I know the database should be restored from backup and logs reapplied. That’s the first and generally recommended approach any time a DB is suspect, whether it’s from log or data file corruption.But if I have no backups then we follow below steps ( after Googling I found these steps on most of the websites ):
1.EXEC sp_resetstatus ‘yourDBname’;
2.ALTER DATABASE yourDBname SET EMERGENCY
3.DBCC checkdb(’yourDBname’)
4.ALTER DATABASE yourDBname SET SINGLE_USER WITH ROLLBACK IMMEDIATE
5.DBCC CheckDB (’yourDBname’, REPAIR_ALLOW_DATA_LOSS)
6.ALTER DATABASE yourDBname SET MULTI_USER
Now my question is,
1. If after executing DBCC CHECKDB at 3rd step, it shows inconsistency.Then I will execute SET SINGLE USER WITH ROLLBACK & if after executing DBCC CHECKDB at 3rd step, no errors found. Then what will be the steps?
2. When we execute DBCC CHECKDB (' DBNAME ', REPAIR_ALLOW_DATA_LOSS) how can we recover lost data during process.As far as I know some data will loss and if it will happen then business will get suffered.
3. Why run DBCC CHECKDB() WITH REPAIR_ALLOW_DATA_LOSS if there are no consistency errors in the database?
For a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?
In a server we had File Growth,And then We had to Add New Hard Drive And New File On It.And Now We have New server with a Huge Hard Drive.But all files remaind.Can I Reduce This files to One data file or not ?
View 3 Replies View RelatedI need to recover some data in a table but i'm not 100% sure the right way to do this safely.
I'll need to query the two tables to compare the before and after but how do i go about restoring/attaching the backup database to SQL without causing conflicts?
If I restore, I assume this would just overwrite which is obviously the worst thing that can happen. if i attach the backup, how does this affect the current live DB? how do i make sure that it's not getting accessed and mistaken for the live DB?

Hi,
View 12 Replies View RelatedRecently, 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
View 1 Replies View RelatedHello!
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?
Thanks in advance.
Greetings,
Rens Voogd
