Duplicate a Database in SQL Server 2014 - sql-server

I have a live database. I need to create a test database with all the data from the live one, but I've encoutneered an error. I've tried to create this new one by restoring from a "live database .bak", but an error message appears saying that could not do the process because the database is in use. Also, I don't know why but after that, the live database starts restoring and keep on it until getting stuck. It does not finish restoring and I have to force stop, deleting the live database and restoring from scratch. Checking the activity log it seems that it goes to restoring mode after failing to create a backup of the database log and that's what happens right after I try to create the new test database using the .bak.
What am I doing wrong? Is there another way to duplicate the live database to use it as a test one?
Note: I've done the process when nobody is using the DB or connected to it but no success.

You need to relocate/rename the Files. Just changing the Database name that you are restoring to may not be changing the Database File and Log File that SQL is trying to actually create when you perform the restore. Go to the Option page of the Restore Database and ensure the files are pointing to Valid locations and not trying to utilize the same files as the Live database.

--At First take ypur database backup and restore it as DatabaseName_Test and also change Datafiles As database _test.mdf and DatabaseName_test_log.ldf
--try to follow as below script
USE master
GO
BACKUP DATABASE [DatabaseName]
TO DISK = N'D:\SQLSERVER_Installation\setup\MSSQL12.SQLSERVER2014\MSSQL\Backup\DatabaseName.bak'
WITH COPY_ONLY, NOFORMAT, NOINIT,
NAME = N'DatabaseName-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10
GO
USE [master]
RESTORE DATABASE [DatabaseName_Test] FROM
DISK = N'D:\SQLSERVER_Installation\setup\MSSQL12.SQLSERVER2014\MSSQL\Backup\DatabaseName.bak'
WITH FILE = 2,
MOVE N'DatabaseName' TO N'D:\SQLSERVER_Installation\setup\MSSQL12.SQLSERVER2014\MSSQL\DATA\DatabaseName_test.mdf',
MOVE N'DatabaseName_log' TO N'D:\SQLSERVER_Installation\setup\MSSQL12.SQLSERVER2014\MSSQL\DATA\DatabaseName_test_log.ldf', NOUNLOAD, STATS = 5

Restoring database from script

I have created a small scrip to restore databases from backups. Once the script is run it displays
RESTORE DATABASE successfully processed 28818 pages in 1.568 seconds
(143.584 MB/sec).
I have more code to alter the database, alter a few views and sp too but I am getting the following error; User does not have permission to alter database 'GreyGoo', the database does not exist, or the database is not in a state that allows access checks.
I have noticed too that I cannot see the database in the object explorer
this is what I use to restore the DB from a backup
if DB exists set to a single user
if DB exist drop database
Ran the below script
RESTORE DATABASE GreyGoo FROM DISK = 'C:\Bkp\GreyGoo_backup_2020_03_02_180002_5403592.bak'
WITH
MOVE 'GreyGoo' TO 'C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\DATA\GreyGoo.mdf',
MOVE 'GreyGoo_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\DATA\GreyGoo.ldf',
REPLACE;
set DB to multi-users and other properties
So what is the problem and how can I solve it, I am currently testing my code on SQL Server 2008
Thanks
During your restore process, you will need to ensure your
login / permissions are correct.
if another previous database with same name is not there, if so delete it. Perhaps from a previous attempt
You can also turn off recovery option like below, recovery is default
RESTORE FILELISTONLY
Sample -- MSDN
USE master;
GO
-- First determine the number and names of the files in the backup.
-- AdventureWorks2012_Backup is the name of the backup device.
RESTORE FILELISTONLY
FROM AdventureWorks2012_Backup;
-- Restore the files for MyAdvWorks.
RESTORE DATABASE MyAdvWorks
FROM AdventureWorks2012_Backup
WITH RECOVERY,
MOVE 'AdventureWorks2012_Data' TO 'D:\MyData\MyAdvWorks_Data.mdf',
MOVE 'AdventureWorks2012_Log' TO 'F:\MyLog\MyAdvWorks_Log.ldf';
GO
EXEC msdb.dbo.sp_delete_database_backuphistory #database_name = N'MYDB'
GO
USE [master]
GO
/* Database [MYDB] */
DROP DATABASE [MYDB]
GO
USE [master]
RESTORE DATABASE [MYDB] FROM DISK = N'E:\FTP\local_MYDB_01.bak' WITH FILE = 1, MOVE N'blank' TO N'E:\DBs\2019\MYDB.mdf', MOVE N'blank_log' TO N'E:\DBs\2019\MYDB.ldf', NOUNLOAD, STATS = 5
GO

Database restore is missing tables

I am using SSMS 2017 and attempting to restore a SQL Server 2016 backup (.bak) file to a new database (the data file and log file names in the original backup are different from the new database I am restoring to), so for example, db1.bak is being used to create a new database called db2 through a restore operation.
After the restore completes, all stored procedures and views are present, but none of the tables are there.
These are the steps I've taken in SSMS to perform the restore:
Right click the Databases folder
Select "Restore Database"
Under the General Page: For "Source" I choose Device and select the db1.bak file, and for "Destination" I enter the name of the new database to be created from the backup (db2)
Under the Files Page I select Relocate all files to folder (both Data and Log folder paths have been pre-populated with the correct names) as have the Logical File Name and the Restore As paths.
Under the Options Page I either select nothing or select Overwrite the existing database (WITH REPLACE).
Once the restore completes "successfully" I expand the newly created db2 and click to expand the tables and receive this error message:
What am I doing wrong?
Here is the script:
USE [master]
RESTORE DATABASE [PdsClone] FROM DISK = N'F:\SQLBackups\PDS_backup_2017_12_12_001015_0199267.bak' WITH FILE = 1, MOVE N'PDS_Data' TO N'E:\Program Files\Microsoft SQL Server\MSSQL13.PDS\MSSQL\DATA\PdsClone.mdf', MOVE N'PDS_Log' TO N'E:\Program Files\Microsoft SQL Server\MSSQL13.PDS\MSSQL\DATA\PdsClone_log.ldf', NOUNLOAD, REPLACE, STATS = 5 GO
UPDATE
I had the server group add another disk to that server and moved the SQL backups there, and I was able to successfully complete the restore this morning. I had previously cleaned off most of the backup files, but could it have been a space issue that prevented the tables from showing up in the restore? Every try it indicated success but no tables. They are there now, and I am thankful for your suggestions and help!
Not really an answer to what happened, but perhaps SSMS was doing something a little buggy as #JeroenMostert suggested.

How do I make a copy of an SQL Server database and connect to it?

I'm working on vb.NET 2013 and SQL server 2008R2.
I have this situation to resolve:
I have a database "DB1". I want to create a copy of this database on the same SQL server with another name "DB2", and after make this database ready to connect.
How can I do this through code from Vb.NET?
Check out this tech net link for restore with new file names.
http://technet.microsoft.com/en-us/library/ms190447(v=sql.105).aspx.
Take a backup of database one (DB1).
Verify backup is valid.
Get correct logical and physical file names
Restore with a move command to create database two (DB2).
Change ownership to SA. Defaults to SQL login that creates the database
Here is a script that I tested on my laptop. Nice thing about backup is no need for down time. If you decide to take off line, copy data files, and create database for attach, down time is created.
-- Sample database
USE AdventureWorks2012;
GO
-- 1 - Make a backup
BACKUP DATABASE AdventureWorks2012
TO DISK = 'C:\mssql\backup\AdventureWorks2012.Bak'
WITH FORMAT,
MEDIANAME = 'SQLServerBackups',
NAME = 'Full Backup of AdventureWorks2012';
GO
-- Use master
USE master
GO
-- 2 - Is the backup valid
RESTORE VERIFYONLY
FROM DISK = 'C:\mssql\backup\AdventureWorks2012.Bak';
GO
-- 3 - Check the logical / physical file names
RESTORE FILELISTONLY
FROM DISK = 'C:\mssql\backup\AdventureWorks2012.Bak';
GO
-- 4 - Restore the files change the location and name
RESTORE DATABASE Adv2012
FROM DISK = 'C:\mssql\backup\AdventureWorks2012.Bak'
WITH RECOVERY,
MOVE 'AdventureWorks2012_Data' TO 'c:\mssql\data\MyAdvWorks_Data.mdf',
MOVE 'AdventureWorks2012_Log' TO 'c:\mssql\log\MyAdvWorks_Data.ldf';
GO
-- 5 - Switch owner to system admin
ALTER AUTHORIZATION ON DATABASE::Adv2012 TO SA;
GO

Create Duplicate SQL Database for Testing

I have created a database on SQL server and a front end user application in winforms c#.
It's up and running and working fine, but I've now been asked to set up a test version by the client for training new employees, so they can put in dummy data whilst they are trained without effecting the 'real' live database.
When I installed the database I had it all scripted, but things have changed since, and I don't particularly want to script all the tables again.
Is there a fast, convenient way of duplicating the database (and its data) on the same server, but under a different name?
EDIT (subsequent to Tony Hopkinson post)
I've got as far as this
exec sp_addumpdevice 'Disk','MyDatabaseBackup',N'D:\MyDatabaseBackup'
Restore Database MyDatabase From MyDatabaseBackup With File = 1,
Move 'MyDatabase' To N'C:\Program Files\Microsoft SQL
Server\MSSQL11.SQLE\MSSQL\DATA\MyDatabaseTEST.mdf',
Move 'MyDatabase_Log' To N'C:\Program Files\Microsoft SQL
Server\MSSQL11.SQLE\MSSQL\DATA\MyDatabaseTEST_log.ldf',
NORECOVERY, NOUNLOAD, STATS = 10
RESTORE LOG [MyDatabaseTEST] FROM [MyDatabaseBackup] WITH FILE = 2, NOUNLOAD, STATS = 10
exec sp_dropdevice MyDatabaseBackup
But I'm getting the following error message
Msg 3234, Level 16, State 2, Line 2
Logical file 'MyDatabase' is not part of database 'MyDatabase'. Use RESTORE FILELISTONLY to list the logical file names.
Msg 3013, Level 16, State 1, Line 2
RESTORE DATABASE is terminating abnormally.
Msg 3154, Level 16, State 4, Line 6
The backup set holds a backup of a database other than the existing 'MyDatabaseTEST' database.
Msg 3013, Level 16, State 1, Line 6
RESTORE LOG is terminating abnormally.

use copy database option in SQL server management studio
I found this method to be most effective on SQL Server 2005 and 2008, Express Editions:
From the Microsoft Docs:
Right click on the database you want to duplicate and choose Tasks->"Back Up..."
Save the back up to a .bak file
Right click on the "Databases" folder in the Object Explorer in SQL Server Management Studio
Choose "Restore Database"
As the source, select "File" and point to the .bak file you created earlier.
Change the name of the database to restore to (this was the key step for me - you are not constrained to the options in the dropdown.)
SSMS will restore your .bak file to a new database, according to the name that you give it.
First do a full backup your current database, which of course you have :)
The you restore it to another one
e.g. something like
exec sp_addumpdevice 'Disk','LiveDataBackup',N'Insert backup file name here including path'
Restore Database TestData From LiveDataBackup With File = 1,
Move 'LiveData' To N'Path to where sqlserver expects the mdfs to be\TestData.mdf',
Move 'LiveData_Log' To N'Path to where sqlserver expects the ldf to be\TaxData1.ldf',
NORECOVERY, NOUNLOAD, STATS = 10
RESTORE LOG [TestData] FROM [LiveDataBackup] WITH FILE = 2, NOUNLOAD, STATS = 10
exec sp_dropdevice LiveDataBackup
Above assume your live database is cunningly named LiveData and test, TestData.
The path to where the mdf and ldf will be depends on the version of sql server and the instance name
It should be something like
C:\Program Files\Microsoft SQL Server\MSSQL11.DENALI\MSSQL\DATA\
MSSQL11 because it's sql 2012, and DENALI is my instance name and it was installed by default in C: \Program Files
Also there's no with replace, so if you wanted to run it again, you'd need to Drop your test database.
There's probably some way to do this from the GUI, but I found it a massive PIA trying to relate the UI, to what I wanted to do.
using MS SQLServer 2012, you need to perform 3 basic steps
first, generate .sql file containing only the structure of the source DB
=> right click on the source DB and then Tasks then Generate Scripts
=> follow the wizard and u can save the .sql file locally
Second, replace in .sql file the source db with the destination one
=> right click on the destination file, open the .sql file and press New Query and Ctrl-H or (edit - find and replace - Quack replace)
finally, populate with data
=> right click on the detination DB, then Tasks and then Import Data
=> Data source drop dow set to ".net framework data procider for sql server" + set connection string text field under DATA ex: Data Source=Mehdi\SQLEXPRESS;Initial Catalog=db_test;User ID=sa;Password=sqlrpwrd15
=> Same thing to do with the destination
=> check the table you want to transfer or check box besides "source :....." to check all of them
you are done.
You want to copy one Database_Production to Database_Testing in the same server. I would take database_production database as an example. I tested it in my server successfully.
Firstly, backup the database Database_Production.
BACKUP DATABASE Database_Production TO DISK ='H:\test\Database_Production.bark';
Secondly, restore Database_Production and this could rename the database name to Database_Testing.
RESTORE DATABASE Database_Testing
FROM DISK='H:\test\Database_Production.bark'
WITH
MOVE 'Database_Production_Data' TO 'H:\test\Database_Testing_Data.mdf',
MOVE 'Database_Production_log' to 'H:\test\Database_Testing_Data.ldf';
GO
Then the database Database_Production is copied to database Database_Testing. The MOVE statement causes the data and log file to be restored to the specified locations. You do not need to create database Database_Testing and the script would create it.
Dump your database into a backup file
Re-create your database from your dump - that is a script which you can run - with different name (that you have to change into the script)
You can follow (this)
If you need to create a database on the same server just create the empty database. Right Click on it and Select Restore-> Choose the database you want to make a copy of and click okay.

How to recover database from MDF in SQL Server 2005?

I have an MDF file and no LDF files for a database created in MS SQL Server 2005. When I try to attach the MDF file to a different SQL Server, I get the following error 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.
I would like to accomplish any one of the following options:
Attach the database without data loss (unlikely but would save me some time).
Attach the database with data loss (whatever transactions were open are lost).
Recover the schema only (no data) from the MDF file.
What SQL commands can I try to get my database going again?
I found the following document on Experts Exchange.
patrikt:
You will have data loss but it can be done.
1. Detach database and move your mdf to save location.
2. Create new databse of same name, same files, same file location and same file size.
3. Stop SQL server.
4. Swap mdf file of just created DB to your save one.
5. Start SQL. DB will go suspect.
6. ALTER DATABASE yourdb SET EMERGENCY
7. ALTER DATABASE yourdb SET SINGLE_USER
8. DBCC CHECKDB (yourdb, REPAIR_ALLOW_DATA_LOSS)
9. ALTER DATABASE yourdb SET MULTI_USER
10. ALTER DATABASE yourdb SET ONLINE
Here are details that cover parts 2) and 3) in case re-creating log doesn’t work which can happen if MDF file is corrupted.
You can recover data and structure only by reading MDF file with some third party tool that can de-code what’s written as binary data but even with such tools you can’t always do the job completely.
In such cases you can try ApexSQL Recover. From what I know this is the only tool that can do this kind of job but it’s quite expensive.
Much better idea is to try to recover these from any old backups if you have any.
FROM a post at SQL Server Forums Attaching MDF without LDF:
If you want to attach a MDF without LDF you can follow the steps below
It is tested and working fine
Create a new database with the same name and same MDF and LDF files
Stop sql server and rename the existing MDF to a new one and copy the original MDF to this location and delete the LDF files.
Start SQL Server
Now your database will be marked suspect 5. Update the sysdatabases to update to Emergency mode. This will not use LOG files in start up
Sp_configure "allow updates", 1
go
Reconfigure with override
GO
Update sysdatabases set status = 32768 where name = "BadDbName"
go
Sp_configure "allow updates", 0
go
Reconfigure with override
GO
Restart sql server. now the database will be in emergency mode
Now execute the undocumented DBCC to create a log file
DBCC REBUILD_LOG(dbname,'c:\dbname.ldf') -- Undocumented step to
create a new log file.
(replace the dbname and log file name based on ur requirement)
Execute sp_resetstatus
Restart SQL server and see the database is online.
UPDATE: DBCC REBUILD_LOG does not existing SQL2005 and above. This should work:
USE [master]
GO
CREATE DATABASE [Test] ON
(FILENAME = N'C:\MSSQL\Data\Test.mdf')
FOR ATTACH_REBUILD_LOG
GO
have you tried to ignore the ldf and just attach the mdf:
sp_attach_single_file_db [ #dbname = ] 'dbname' , [ #physname = ] 'physical_name'
i don't know exactly what will happen to your open transactions (probably just lost), but it might get your data back online.
-don
See here : Rebuild master and restore system databases from complete disk failure which has a very nice explanation
Just had this problem myself, but none of the above answers worked for me.
But instead, I found this which worked a treat and so I thought I'd share this for everyone else:
http://www.kodyaz.com/articles/sql-server-attach-database-mdf-file.aspx
Found a another way that works completely:
Create new database with same name to default database location.
Stop SQL server.
Copy old mdf file to overwrite newly created mdf file and delete new ldf file
Start SQL Server, database will be in emergency mode
Detach the emergency mode database
Copy original ldf file to default database location (where new LDF file as created and deleted under step 3 above.
Attach the database MDF file.
I got a working database after trying all of the above that failed for me.
I hope it is easy to do so,
Open SQL Server
Click New Query
Execute the following query
sp_attach_single_file_db #dbname='dbname',#physname='C:\Database\dbname.MDF'
Where dbname is you want to show in Object Explorer, where #physname is the local filepath location of your mdf file.
Hope it will help someone, i done by above, got both structure and also data.
Tested in Sql Server 2000 and 2008. In Sql Server 2000 it is not working, but works perfectly in 2008.
