.MDF file issue.

hi team,
we have one old database, this old database we don't have any backup.
here problem is this database datafile(.MDF) file was corrupted unable to access the this database, what we can do how we access the this database.

here we don't have any database backup,that is the problem .
how we can resolve this issue, this issue happen past 5 days on words,
You resolve this issue by restoring a clean backup, and if you don't have any you are in serious trouble, at least if this database is critical to you.
Well, you "only" have a checksum error. This could mean that the data is largely correct. This is the scope about the checksum: When SQL Server writes a page to disk, it computes a checksum which it stores on the disk.
When SQL Server reads the page, it recomputes the checksum and compares with what is stored on the page. If there is a mismatch, it sounds the alarm, becuase it indicates that the data has been altered when it was supposed to be at rest on the disk.
First, run DBCC CHECKDB, to see how wide the range of corruption is. I don't know for sure, but I suppose that it will produce an error for page with an incorrect checksum. It may also produce more errors, if the bits that have been flipped are in the
internal page structure.
I could go on, but I have not performed this sort of exercise myself, and I don't want to give half-hearted advice in a potentially serious situation. I would recommend that you open a case with Microsoft. They will not repair your database, but they
may help you with the process how to copy data out of the database. They should also help you with interpreting the error messages, so you that can judge exactly how critical these pages are.
And keep in mind that these errors do not come out of the blue. You should consider the hardware on which you have this file to be suspect and replace it. And you should make sure that if you have other databases that are dear to you that they are backed
up properly...

You are trying to attach SQL Server 2012 database files to SQL Server 2008 R2 which is not allowed, you either need to upgrade your SQL Server 2008 to 2012 or alternatively you can generate all scripts from SQL Server 2012 and execute it in SQL Server
2008 R2.
You can refer below link to how to generate script.

Connecting to a local SQL server .mdf file

Hi all,
In doing some prototyping of my database I started working with a local copy of an SQL Server database since it so conveniently integrated with the Visual Studio .NET tools I use. Now that I have spent far too much time working on a local prototype, I would very much like to migrate it to our in-house database rather than rewrite the whole thing (it is quite large in terms of tables and constraints and none of our in-house tools generate code from ER diagrams).
Seeing that SQL Developer had a migration utility I pounced at a chance to use it. I installed it as well as the recommended JDBC driver; however, it occurs to me that I have no idea how to connect to a local database file using the host name and port fields given to me. Is there some convenient way to configure SQL Server 2005 to forward this file to some kind of local host? Or is there any other driver for use with a local .mdf file? Help would be greatly appreciated.

While it does come with a copy of SQL Server with it, visual studio suspiciously just asks for a file name, so I would assume it reads directly from the .mdf
I have a copy of SQL Server 05 on the machine, but I haven't done anything in the way of server side configuration before, so I can't even guess how to direct it to serve the file.
All software packages involved are:
Windows XP
SQL Server 2005
Visual Studio .NET 2005
SQL Developer 1.5.1
Oracle client 10g connecting to an Oracle 9i release 2 server
Any pointers to the right direction or alternate migration solutions would be great.
Edit: I am highly suspicious that Visual Studio was connecting to this file through SQL Server Express and not my standard edition copy, and it is therefore not attached to the database, the solution is not looking entirely easy, so an alternate migration may be a better choice. Thanks in advance for any help.
Edit: Well my suspicions were confirmed. I attempted several solutions. First of which being the MS SQL Express publishing wizard so that I could publish to SQL and run the script via Toad or SQL Plus; however, it only targets MS SQL Server 2000 or 2005 which would result in a lot of hand editing in terms of migration. Attempting to find a script converter did not help as they all either failed outright or demanded a connection to the datbase via ODBC or JDBC (which doesn't support SQL Express' less than clever attach on connection ideas). This led me to the alternate solution of trying to attach the file to my main database and connect to it; however, the SQL Server command prompt has some sort of permissions issue with my office security setting (though I can edit files fine) and results in failure.
I think it is about time to throw in the towel and just work it out by hand. This would be greatly expedited by any visual database tools that generate code from ER diagrams if you happen to know of a freeware solution. We lack an internal copy of Oracle Designer and the free license only permits a single prototype. So any suggestions on the front of freebie visual object relational tools and alternate migration ideas would be of great help. Until then I'll be grinding through it with moderate dissatisfaction.
Thanks again.

How to recover database from .mdf file

create a database of
equal size to the one you're trying to attach
shutdown the server (Stop)
swap in the old mdf file (replace new .mdf file with .mdf file to be recovered )
Location: C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA
bring up the server (start) and let the database attempt to be recovered and then go into suspect mode
put the database into emergency mode with ALTER DATABASE
run DBCC CHECKDB (dbname, REPAIR_ALLOW_DATA_LOSS) which will rebuild the log and run full repair
Your database will be available again but you'll have lost data and the data won't be transactionally consistent
USE [master]
GO
ALTER DATABASE [RdmStoreInformation] SET EMERGENCY
GO
ALTER DATABASE [RdmStoreInformation] SET SINGLE_USER
GO
DBCC CHECKDB ([RdmStoreInformation], REPAIR_ALLOW_DATA_LOSS)
GO
ALTER DATABASE [RdmStoreInformation] SET MULTI_USER
GO
ALTER DATABASE [RdmStoreInformation] SET ONLINE
GO
This is a issue I had to fix and it's solution listed here for your reference(I gathered all the In-formations by surfing web)

Interesting, did you get any errors trying to attach the .mdf file?

Opening MDF files in Diadem generated with Vector CANape v7.0?

Hi all,
I have a Vector CANape v7.0 data aquisition system that generates files in MDF format. I found the Diadem data plugin for MDF files and installed it. I can open the files, see the parameter names, but all the data is 0 (and it should not be).
The plugin looks up to date and the description mentions MDF version 3.0 & 3.2. We have CANape version 7.0. How do those numbers correspond? How can I open this file correctly?
Plugin Description:
This DataPlugin supports reading / importing of Bosch MDF data files, ETAS INCA® MDF data and Vector CANape® and other products from Vector. The DataPlugin supports MDF files up to version 3.2. The MDF DataPlugin also supports writing of MDF 3.0 and 3.2 files. Writing behavior is controlled by the root property 'version'; set version to "MDF 3.2" to write MDF 3.2 files.
The Measure Data Format (MDF) is well established in the automotive industry for recording, exchanging, and post-measurement analysis. MDF files are produced by eg. INCA® from ETAS, and by CANape® and other products from Vector.
Thanks- Dshow
P.S. I have tried this on Diadem v10.1 and 11 with the same results. Thx
Message Edited by Dshow on 07-13-2009 02:12 PM
Solved!
Go to Solution.

Hello Dshow,
Since I don' have any MDF files to test this with, I can't help with your immediate question. I can offer up an alternative though:
With version 11.1, DIAdem has gained the ability to load CAN files directly through the "CAN Converter" that can be found in the NAVIGATOR "File" menu. You can test this with the free evaluation version that can be found at http://www.ni.com/diadem/ - this might take care of the issue you are having. It also offers a number of additional features you might be interested in ...

How to restore .MDF file to other instance

Hi All
I need your help, one of my sql cluster crashed. I rebuild SQL Cluster with same instance name and cluster name. I want to know how to restore one of our user database .MDF database file. By mistaken i deleted .LDF file. And now i'm facing challenge
to restore .MDF file.
If anyone face this issue, please share you experience.
Regards
Rinks

I entirely agree with Dan that you should restore the database from a clean backup.
Since the cluster crashed, I suspect that the database was not shut down cleanly and in this case you will not be able to attach the MDF with the suggestions Dan made.
It is possible to what Paul Randall calls a "hackattach", but I am not going to describe this here. You will be able to access the database, but the database may be full of corruptions. So I really hope that you have a backup.

Cannot navigate to some folders when attempting to attach .MDF files to database in Management Studio

Hello,
I have Windows 7 ultimate, SP1 and login to a SBS2003 R2 domain as administrator.
I use SQL Server Management Studio 10.50.2500.0 to connect to a local instance of SQL Server 2008 R2 using Windows Authentication.
When I attempt to attach a database .MDF file that is not in the C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA folder, the Locate Database Files dialog box will not allow me to navigate to other folders to find databases.
It does not give an error, it simply does not open the selected folder.
How do I allow the Locate Database Files dialog box to navigate to other folders to locate other .MDF files?
Any help would be grate fully appreciated.
Thanks,
Tony

I’m not sure of what you mean by “the rights”, but I can see all folders and files on all machines when using Windows Explorer. I cannot navigate to them through the Locate Database Files

Also, this has nothing to do with the server. This issue involves my local computer.

If tempdb .mdf file out of disk space and we do nothing to fix, what could happen? Will anything crash?

Will anything crash or stop working if tempdb .mdf file out of disk space?

It might crash, sql server will stop responding or you may not able to perform any action until space allocated to tempdb.
Running out of disk space in tempdb can cause significant disruptions in the SQL Server production environment and can prohibit applications that are running from completing operations.

Thanks
I loaded the MDF plugin and started DIAdem.
I have since loaded the data into the Data portal but DIAdem is cycling between "Not Responding" and "Responding" and has been doing so for over 2 hours now. I am not sure if it is working, but I will give it some more time before I kill the process.
Thanks for your help nonetheless.

Connecting to sql server database mdf file without installing sql server on client machine?

I am creating a window application that need to use sql server database. I want to install this application to client machine without installing sql server so that my application can still connect to a database i.e mdf file that i will be providing at client
system.
How can i connect to a database(mdf) on client machine through my window application without installing sql server. ? I dont know is it possible or not.
If possible what will be the connection string in that case. Database need not be used in network.

you cant connect and view the internals of mdf file unless it being attached to a sql server instance as a database.
The sql server instance can be installed in any box which is in the same domain and then you can connect from your application to it.

Need help changing from SQL dbo to mdf file

My project was started using dbo is there a way to change this to an mdf without changing out the database.

I think you answered my question the datasets in my project are connected to sqlexpress instance, Iwant to remove this connection and add a connection to an MDF file in my project. Maybe this will help explain my question better.
You cannot directly add connection to mdf file.But you can achieve this by first attching this MDF file to SQL express( this has some limitations like max of 4 Gfile can be attached to Sql server 2008 and 10 G for 2012).Is this you want to achieve ?

Existing Replica MDF file size is increased in size than the New replica install

Please I need help here.I really really appreciate your help.
Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to
the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs.
I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs.
I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool.
The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initiall replica set up times. Any input will be greatly appreciated.
Thanks,
Asha.

Creating mdf file from a database project in Visual Studio for Web

I am very new to database programming in Visual Studio and SQL Server Express LocalDB. I went through a walk through of setting up a database project (using visual studio express 2013 for web and SQL Server Express LocalDB), adding tables and entering data
and everything worked fine:
http://msdn.microsoft.com/en-us/library/ms233763.aspx
Then I wanted to move on to trying to build a simple application to access this database so I looked into the following tutorial:
http://msdn.microsoft.com/en-us/library/ms171890.aspx
In a nutshell the tutorial says to add a new datasource and navigate to the database file, and it is looking for an .mdf file.
The database project that I created does not have an mdf file in it, only sql file, visual studio project, dbmdl file, options file, source browser database, etc.
How do I create this .mdf file, that step didn't seem to be explained in the first tutorial. I tried running the project, but didn't see any build options for creating the .mdf file. Again, sorry for the absolute beginner question.
