Using Detach/Attach Database To Copy/move

May 9, 2001

This might sound dumb, but BOL says you can use detach/attach to "MOVE" a database but can you detach and copy the files to a new server, leaving the files on the original and running the attach on the new and the old? (effectually a way to copy)? I know how to use data transformations/import,export was curious?

Help appreciated!!

Detach, Move, Attach Again

Mar 23, 2006

I created a db in ssms; I detached it and moved it into a subdirectory of a vb app. Now sql server says the database does not exist. If I recreate the database in smss, I can run an INSERT INTO using that db as the destination. However, this only works if I keep it in the mssql data directory. How can I move it to the apps subdirectory so that it can be deployed with the app and still work? BTW, I also tried creating the databases in VS2005 with same results.

This is the connection string (tried this and non-express version with same results):

  strDbConn = "Provider=SQLNCLI;Data  Source=.SQLEXPRESS; AttachDbFilename=" & DbPath & ";User Instance=True;Trusted_Connection=Yes"

This is the sql statement:

  sqlCopyTable = "SELECT * INTO "
  sqlCopyTable = sqlCopyTable & CleanDbName & ".dbo." & CleanTableName
  sqlCopyTable = sqlCopyTable & " FROM " & RawTableName & ";"
  ConnectSQLExpress RawDbPath, "Source"
  ConnectSQLExpress CleanDbPath, "Destination"
  SourceDbConn.Execute sqlCopyTable

Detach-copy-attach: Can Not Copy Files - Getting Access Denied

Feb 28, 2008



Hi!
I did:
alter database mydb set single_user with rollback immediate;
exec sp_detach_db @dbname='mydb', @keepfulltextindexfile='true';

then I tried to copy files to new location on other drives, same server but got
>>Cannot copy <myfile>: Access is denied
Make sure the disk is not full or write-protected and that the file is not currently in use<<

I also tried rename of file without success.
I also tried with db service stoppet (not preferred) without success.

How to find out, which process locks the files?
Best regards

Detach/attach Move Fails To Bring Over Roles & Logins Correctly

May 23, 2001

A database move was accomplished by detaching the database from the legacy server and attaching it to the new server. The servers ran NT 4, SP6a, SQL 7 SP2. The new server had the same name and IP as the old server.

However that process (detach attach) does not bring over the users (who had access to the database on the legacy systems) correctly.

Under databases, roles the users existed. Under security, logins they did not.

We were obliged to drop the roles and recreate the logins and assign new roles. In the case of an NT user group we were unable to drop it. We had to create a new one and add the users to that group under User Manager.


So far I have not found anything that deals with the user account/role problem.

We have to move a similar database tonight. Do any of you know of an alternative "move" that brings the user roles/logins across correctly?

Thanks in advance.

Database Detach/attach

Jan 2, 2004

An original database (eg A.mdf) is imported/exported to a different server as named B.mdf. The detach of A.mdf was unitentionally not done. It seems that both the database were updated.

A.mdf - 123000KB 25/12/2003
A_log.ldf - 14000KB 25/12/2003
B.mdf - 67000KB 25/12/2003
B_log.ldf - 1024KB 25/12/2003

In this case, which mdf & ldf should be the correct database?
If I I remove A.mdf database by "detach", will B.mdf database work?

SQL server 2000 and SP3 installed.

Assistance is appreciated

Question On Detach/attach Database

May 21, 2007

Hi, all experts here,

Thank you for your kind attention.

I am having a question on detach/attach database. As when we detach/attach database, we have to copy both of .mdf and .ldf files to the targeted filepaths, in this case, when the database is large, then it takes a pretty while to copy the physical files though. In this case, I dont really see the point to detach/attach the database? Instead, backup/restore may be faster? (also, as detach the database, the files has to be taken offline)

Just confused about the way we trasfer database files with detach/attach. I am looking forward to hearing from you shortly for any advices for that.

With best regards,

Yours sincerely,

Detach,attach Db And Login,user And Master Database

Jan 30, 2000

I have similar question like Tim asked but from a different angle. I wish I pose my question here too anybody can help answer this.

I tried to use detach and attach method to do backup of the user database (not master, maybe we can do master too) on another server, but it looks the login and permission credential would not go together. I come to see different kind of message I tried to login as non-sa user after I attatch the database on different machine. I would be denied for SQL timeout. It looks like loginand user dose not exist in new server because I did not move master database too. But even if I recreate the login when I tried to associate user with login I will see a message saying user or role already exist in database. If I go back to check the user it did not show up on enterprize manager on that database.

So my question would be
1). how to move login and user together with user database.
2) do we have to move master database where the login infor. reside
3). if so how to move master database from one server to another when other server already have master database exist?

Hope somebody can answer this.

Backup/Restore Vs Attach/Detach 2000 Database To 2005

Jul 15, 2006

I'm trying to see the differences between Backup/Restore and Attach/Detach. I backup and detach a database from SQL Server 2000 SP3 and then attach and restore it to SQL Server 2005 SP1.

The differences I noticed are:

1. The restored database has a much larger initial size (database size is same) for data and log.
2. The attached database has a last backup date
3. If the backup is restored over a database, the restored database is showing owned by the database owner of the database restored over but syslogins and sysusers do not match.

I don't understand why #1 happens.

Are there any other differences between Backup/Restore and Attach/Detach?



Thanks,

Peter

Attach And Detach Db Woes

Jan 4, 2002

I have developed a db on a local machine (98) and would like to move it to another machine running nt 4 where it will function as a production db. I am mapped to see the other server (called "labnt"). The drive on "labnt" is partitioned, with the c drive holding programs, and the e drive designed to hold the data.

I would like to move the db (called SNB01) to the MSSQLData subdirectory on the e-drive. I have tried the following sproc to detach:

EXEC sp_detach_db 'SNB01', 'true'

And the following to reattach:
EXEC sp_attach_db @dbname = 'SNB01',
@filename1 = 'labntewmssqldataSNB01_Data.mdf',
@filename2 = 'labntewmssqldataSNB01_log.ldf'

The above path was given me by our network admin guy.


QA gives the following error:
Server: Msg 5105, Level 16, State 4, Line 1
Device activation error. The physical file name 'labntewmssqldataSNB01_Data.mdf' may be incorrect.


Please help. I am thrashing about. D. Lewis

Detach/Attach DB VS Stopping SQL Server

Mar 21, 2002

What problems could be invoked by stopping SQL Server and copying a user databases data and log files and pasting these files over existing files on another machine.

Ex:
MyDB on Server1
MyDB on Server2
Stop SQL Server Server1 and Server2
Copy Server1.MyDB files
Over write Server2.MyDB files
Start SQL Server Server1 and Server2

Make sense. This scenerio seems to work but wonder what side affects could result.

Any comments would be helpful!!

Will this work.

TIA

Moving Db Via Detach Then Copy And Paste 44 Gig Db File?

Aug 21, 2000

Hi,

I have a 44 gig db that I moved to another server via the NT copy and paste method. The db has gotten a little larger, and now NT gets almost to the end, but can not complete -- either starts over completely and just does the last few minutes over and over.

Is there an NT copy and paste limit? Any ideas what the problem is? Is the db mixed up?

Thanks for any help.

Copy .mdf And Attach As New Db

May 2, 2008

I have copied the .mdf and .ldf files from one db and I'd like to attach the copies to a new db on the same server. When I try to attach the copied files I get the error, "the physical file name may be incorrect". Original db filename is "MC_DISC_Data.mdf", I copied this and renamed it to, "MC_Data.mdf" in my sqldata folder. I can see the physical file name is still the original name when I'm trying to attach db using EM, how can I change it to the copied name?

Detach Database .

Feb 12, 2002

Hello Everybody ..

I am trying to detach and attach a database on SQL 7.0 Server with SP 2 through Enterprise manager . However if i right click o the Database and go to all task , i see the ' detach database' greyed out .
The same thing is seen for ' attach Database 'when i try to attach the database .

Although it can done through T-SQL commands also , does any body know the reason why this field is greyed out ?

Does it depend on the SQL 7.0 Service pack or any kind of special permissions ? The same is visible on SQL 2000 Server Enterprise Manager .

Has anybody come across this problem ?

Many thanks in advance
Yatin.
