restore .dat

1 New Member
I am trying to restore a SQL Server database from a .dat file. An earlier question on how to do this elicited the following answer.

"

You need to know how the '.dat' file was created in order to import it. Use
RESTORE FILELISTONLY to determine if this is a database backup:

RESTORE FILELISTONLY
FROM DISK='C:\MyData base.dat'

You can then execute a RESTORE with the desired MOVE options.

RESTORE MyDatabase
FROM DISK='C:\MyData base.dat'
WITH
MOVE 'MyDatabase' TO 'C:\DBDataFiles \MyDatabase.mdf ',
MOVE 'MyDatabase_Log ' TO 'C:\DBDataFiles \MyDatabase_Log .ldf'

If you get an error during the RESTORE FILELISTONLY that states the file
isn't a valid backup, you'll need to investigate further. You might try
opening it using a text editor to see of that provides a clue of the file
format.

"

When I do the RESTORE FILELISTONLY command I get a table with two rows

LogicalName :: PhysicalName :: FileGroupName

Data_V2_1_Data :: C:DATABASES\Dat a_V2_1_Data.MDF :: PRIMARY
Data_V2_1_Log :: C:DATABASES\Dat a_V2_1_Log.LDF :: NULL

The .MDF and .LDF files were not provided to me. Are those something I
need?
What does this result mean? What are possible next steps to extract .MDF, ,LDF files?

The RESTORE with MOVE doesn't work, but I am hoping that if I can get help figuring out teh RESTORE FILELISTONLY commands results the other part will fall into place.

Thank you in advance!

Hello!

Are the column names provided to you legitimate (LogicalName :: PhysicalName :: FileGroupName), you probably have found your answer there...

If you were restoring a database, the extension is the .MDF portion. Although I suspect you alreay know that.

Also, do you have a copy of this database (.MDF file). If you have the data elsewhere, you may find it easier to just make up a different .MDF (database) and update/transfer the data to it.

Not too conventional, but if you need simpler solutions and have a copy, try it:-)
