NB. I don't want to mark the check box in the wizard for deletion. This question's strictly about scripting the behavior.
When I run the following script to get a fresh start, I get the error that the database Duck can't be deleted because it's currently in use.
use Master
drop database Duck
drop login WorkerLogin
drop login AdminLogin
go
Be that as it may (even though I'm the only user currently in the system and I run no other queries but that's another story), I need to close all the existing connections. One way is to wait it out or restart the manager. However I'd like to script in that behavior so I can tell the stubborn server to drop the duck down. (Yes, "typo" intended.)
What do I need to add to the dropping statement?
Try below code.
USE master;
ALTER DATABASE [Duck] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
DROP DATABASE [Duck] ;
For deep discussion see this answer.
You have to kill first all active connections before you can drop the database.
ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE
--do you stuff here
ALTER DATABASE YourDatabase SET MULTI_USER

How do you kill all current connections to a SQL Server 2005 database?
if you're ssms tab is not currently on the db to be dropped (meaning you are in the master db), then these will help:

I need to rename one of my database and tried a query like this
ALTER DATABASE Test MODIFY NAME = NewTest
But this throws an error
Msg 5030, Level 16, State 2, Line 1
The database could not be exclusively locked to perform the operation.
Can any one give me any suggestion?
Try something like;
USE master
GO
ALTER DATABASE Test
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE
GO
ALTER DATABASE Test MODIFY NAME = NewTest
GO
ALTER DATABASE NewTest
SET MULTI_USER
GO
Be aware of the fact that this may not rename the physical file on the hard drive though.
There are a couple of things you need to investigate. The reason you're getting that error could be due to one or more of the following things:
The account you're using does not have permission to run the command
The DB is locked by another process/user
The database contains a file group that is read-only
You can try and force single user mode to check 2.
ALTER DATABASE SINGLE_USER ROLLBACK IMMEDIATE.
That will kill any concurrent connections to the DB allowing you to rule out number two.
You have two options:
Look for and kill all connections like OMG Priories suggest
Open the database in Single Server Mode as described here:
http://technet.microsoft.com/en-us/library/ms345598(v=sql.105).aspx
I need help with setting a database that was restored in SINGLE_USER mode to MULTI_USER. Every time I run
ALTER DATABASE BARDABARD
SET MULTI_USER;
GO
I get this error:
Changes to the state or options of database 'BARDABARD' cannot be made at this time.
The database is in single-user mode, and a user is currently connected to it.
It needs to be in non-SINGLE_USER mode to set it to another mode, but I can’t set the database in any another mode while it is SINGLE_USER mode.
The “user is currently connected to it” might be SQL Server Management Studio window itself. Try selecting the master database and running the ALTER query again.
That error message generally means there are other processes connected to the DB. Try running this to see which are connected:
exec sp_who
That will return you the process and then you should be able to run:
kill [XXX]
Where [xxx] is the spid of the process you're trying to kill.
Then you can run your above statement.
You can add the option to rollback your change immediately.
ALTER DATABASE BARDABARD
SET MULTI_USER
WITH ROLLBACK IMMEDIATE
GO
SQL Server 2012:
right-click on the DB > Properties > Options > [Scroll down] State > RestrictAccess > select Multi_user and click OK.
Voila!
I had the same issue and it fixed by the following steps - reference: http://giladka8.blogspot.com.au/2011/11/database-is-in-single-user-mode-and.html
use master
GO
select
d.name,
d.dbid,
spid,
login_time,
nt_domain,
nt_username,
loginame
from sysprocesses p
inner join sysdatabases d
on p.dbid = d.dbid
where d.name = 'dbname'
GO
kill 56 --=> kill the number in spid field
GO
exec sp_dboption 'dbname', 'single user', 'FALSE'
GO
This worked fine for me.
Step 1. Right click on database engine, click on activity monitor and see which process is having connection. Kill that particular user and execute the query Immediately.
Step 2.
USE [master];
GO
ALTER DATABASE [YourDatabaseNameHere] SET MULTI_USER WITH NO_WAIT;
GO
and refresh the database.
I have just fixed using following steps, It may help you.
Step: 1
Step: 2
Step: 3
Step: 4
Step: 5
Then run following query.
ALTER DATABASE YourDBName
SET MULTI_USER
WITH ROLLBACK IMMEDIATE
GO
Enjoy...!
I actually had an issue where my db was pretty much locked by the processes and a race condition with them, by the time I got one command executed refreshed and they had it locked again... I had to run the following commands back to back in SSMS and got me offline and from there I did my restore and came back online just fine, the two queries where:
First ran:
USE master
GO
DECLARE #kill varchar(8000) = '';
SELECT #kill = #kill + 'kill ' + CONVERT(varchar(5), spid) + ';'
FROM master..sysprocesses
WHERE dbid = db_id('<yourDbName>')
EXEC(#kill);
Then immediately after (in second query window):
USE master ALTER DATABASE <yourDbName> SET OFFLINE WITH ROLLBACK IMMEDIATE
Did what I needed and then brought it back online. Thanks to all who wrote these pieces out for me to combine and solve my problem.
It may be best to log onto the server directly instead of using SQL Management Studio
Ensure that the account you login as is dbowner for the database you want to set to MULTI_USER. Login as sa (using SQL server authentication) if you can
If your database is used by IIS, stop the website and the app pool that use it - this may be the process that's connected and blocking you from setting to MULTI_USER
USE MASTER
GO
-- see if any process are using *your* database specifically
SELECT * from master.sys.sysprocesses
WHERE spid > 50 -- process spids < 50 are reserved by SQL - we're not interested in these
AND dbid=DB_ID ('YourDbNameHere')
-- if so, kill the process:
KILL n -- where 'n' is the 'spid' of the connected process as identified using query above
-- setting database to read only isn't generally necessary, but may help:
ALTER DATABASE YourDbNameHere
SET READ_ONLY;
GO
-- should work now:
ALTER DATABASE Appswiz SET MULTI_USER WITH ROLLBACK IMMEDIATE
Refer here if you still have trouble:
http://www.sqlservercentral.com/blogs/pearlknows/2014/04/07/help-i-m-stuck-in-single-user-mode-and-can-t-get-out/
AS A LAST ALTERNATIVE - If you've tried everything above and you're getting desperate you could try stopping the SQL server instance and start it again
You couldn't do that becouse database in single mode. Above all right but you should know that: when you opened the sql management studio it doesn't know any user on the database but when you click the database it consider you the single user and your command not working.
Just do that: Close management studio and re open it. new query window without selecting any database write the command script.
USE [master];
GO
ALTER DATABASE [tuncayoto] SET MULTI_USER WITH NO_WAIT;
GO
make f5 wolla everything ok !
The code below has worked for me when I didn't know the specific SPID that was used to change into singleuser mode.
use master
GO
select
d.name,
d.dbid,
spid,
login_time,
nt_domain,
nt_username,
loginame
from sysprocesses p
inner join sysdatabases d
on p.dbid = d.dbid
where d.name = 'dbname'
GO
kill 52 -- kill the number in spid field
GO
exec sp_dboption 'dbname', 'single user', 'FALSE'
GO
Tried everything didn't work
Login to that server remotely as we gonna kill all connections
run the below code more than once till it returns completed and no "killing process" test anymore
reactivate it again using the code below the below code
use master GO declare #sql as varchar(20), #spid as int
select #spid = min(spid) from master..sysprocesses where dbid =
db_id('DB_NAME') and spid != ##spid
while (#spid is not null) begin
print 'Killing process ' + cast(#spid as varchar) + ' ...'
set #sql = 'kill ' + cast(#spid as varchar)
exec (#sql)
select
#spid = min(spid)
from
master..sysprocesses
where
dbid = db_id('DB_NAME')
and spid != ##spid end
then to bring it back alive
ALTER DATABASE DB_NAME SET MULTI_USER; GO
This worked fine for me
Take a backup
Create new database and restore the backup to it
Then Properties > Options > [Scroll down] State > RestrictAccess > select Multi_user and click OK
Delete the old database
Hope this work for all
Thank you
Ramesh Kumar
If the above doesn't work, find the loginname of the spid and disable it in Security - Logins
I have solved the problem easily
Right click on database name rename it
After changing, right click on database name --> properties --> options --> go to bottom of scrolling RestrictAccess (SINGLE_USER to MULTI_USER)
Now again you can rename database as your old name.
On more than 3 occasions working with SQL Server 2014, I have had a database convert to Single User mode without me changing anything. It must have occurred during database creation somehow. All of the methods above never worked as I always received an error that the database was in single user mode and could not be connected to.
The only thing I got to work was restarting the SQL Server Windows Service. That allowed me to connect to the database and make the necessary changes or to delete the database and start over.
just go to database properties
and change SINGLE USER mode to MULTI USER
NOTE:
if its not work for you then take Db backup and restore again and do above method again
*
Single=SINGLE_USER
Multiple=MULTI_USER
Restricted=RESTRICTED_USER
After going in to the Single-User mode, a client can establish only ONE connection with the SQL Server, remember that "Object Explorer" takes up a (separate) connection, so if you are trying run a Multi-User statement in a query window, you will get error that in Single-User mode you can't establish another connection.
For me this wasn't the issue though, in my case, there were few automated processes that were persistently (in every few seconds) establishing connections, so as soon as I took the DB into Single-User mode and disconnected myself, one of the processes established/occupied the connection (before I could start my Restore operation). As soon as I'd kill those connections - they'd reconnect and when I ran the Restore command, I would get the error that connection is already occupied.
To resolve this I had to write the kill statements, change of User-Mode statements and Restore operations all in one query window and when I ran them all in one go, voila!!! it worked.
Hope this helps others.
I was having trouble with a local DB.
I was able to solve this problem by stopping SQL server, and then starting SQL server, and then using the SSMS UI to change the DB properties to Multi_User.
The DB went into "Single User" Mode when i was attempting to restore a backup. I hadn't created a backup of the target database before attempting to restore (SQL 2017). this will get you every time.
Stop SQL Server, Start SQL Server, then run the above Scripts or use the UI.
I googled for the solution for a while and finally came up with the below solution,
SSMS in general uses several connections to the database behind the scenes.
You will need to kill these connections before changing the access mode.(I have done it with EXEC(#kill); in the code template below.)
Then,
Run the following SQL to set the database in MULTI_USER mode.
USE master
GO
DECLARE #kill varchar(max) = '';
SELECT #kill = #kill + 'KILL ' + CONVERT(varchar(10), spid) + '; '
FROM master..sysprocesses
WHERE spid > 50 AND dbid = DB_ID('<Your_DB_Name>')
EXEC(#kill);
GO
SET DEADLOCK_PRIORITY HIGH
ALTER DATABASE [<Your_DB_Name>] SET MULTI_USER WITH NO_WAIT
ALTER DATABASE [<Your_DB_Name>] SET MULTI_USER WITH ROLLBACK IMMEDIATE
GO
To switch back to Single User mode, you can use:
ALTER DATABASE [<Your_DB_Name>] SET SINGLE_USER
This should work. Happy coding!!
Thanks!!
What I do:
First I kill all database process, to certificate that database isn't in use.
After I alter the user mode.
Sometimes a process is quickly grabed again from an aplication, and I need run this process one more time...
Replace the expression DATABASE_NAME below, to use your database name.
--Kill process
USE Master
GO
declare #sql as varchar(20), #spid as int
select #spid = min(spid) from master..sysprocesses where dbid = db_id('DATABASE_NAME') and spid != ##spid
while (#spid is not null)
begin
print 'Killing process ' + cast(#spid as varchar) + ' ...'
set #sql = 'kill ' + cast(#spid as varchar)
exec (#sql)
select
#spid = min(spid)
from
master..sysprocesses
where
spid > 50 AND dbid = db_id('DATABASE_NAME')
and spid != ##spid
end
print 'Killing Process completed...'
GO
**--Alter user mode**
ALTER DATABASE DATABASE_NAME SET MULTI_USER;
GO
print 'Alter Database Process completed...'
I need to restart a database because some processes are not working. My plan is to take it offline and back online again.
I am trying to do this in Sql Server Management Studio 2008:
use master;
go
alter database qcvalues
set single_user
with rollback immediate;
alter database qcvalues
set multi_user;
go
I am getting these errors:
Msg 5061, Level 16, State 1, Line 1
ALTER DATABASE failed because a lock could not be placed on database 'qcvalues'. Try again later.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.
Msg 5061, Level 16, State 1, Line 4
ALTER DATABASE failed because a lock could not be placed on database 'qcvalues'. Try again later.
Msg 5069, Level 16, State 1, Line 4
ALTER DATABASE statement failed.
What am I doing wrong?
After you get the error, run
EXEC sp_who2
Look for the database in the list. It's possible that a connection was not terminated. If you find any connections to the database, run
KILL <SPID>
where <SPID> is the SPID for the sessions that are connected to the database.
Try your script after all connections to the database are removed.
Unfortunately, I don't have a reason why you're seeing the problem, but here is a link that shows that the problem has occurred elsewhere.
http://www.geakeit.co.uk/2010/12/11/sql-take-offline-fails-alter-database-failed-because-a-lock-could-not-error-5061/
I managed to reproduce this error by doing the following.
Connection 1 (leave running for a couple of minutes)
CREATE DATABASE TESTING123
GO
USE TESTING123;
SELECT NEWID() AS X INTO FOO
FROM sys.objects s1,sys.objects s2,sys.objects s3,sys.objects s4 ,sys.objects s5 ,sys.objects s6
Connections 2 and 3
set lock_timeout 5;
ALTER DATABASE TESTING123 SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
Try this if it is "in transition" ...
http://learnmysql.blogspot.com/2012/05/database-is-in-transition-try-statement.html
USE master
GO
ALTER DATABASE <db_name>
SET OFFLINE WITH ROLLBACK IMMEDIATE
...
...
ALTER DATABASE <db_name> SET ONLINE
Just to add my two cents. I've put myself into the same situation, while searching the minimum required privileges of a db login to run successfully the statement:
ALTER DATABASE ... SET SINGLE_USER WITH ROLLBACK IMMEDIATE
It seems that the ALTER statement completes successfully, when executed with a sysadmin login, but it requires the connections cleanup part, when executed under a login which has "only" limited permissions like:
ALTER ANY DATABASE
P.S. I've spent hours trying to figure out why the "ALTER DATABASE.." does not work when executed under a login that has dbcreator role + ALTER ANY DATABASE privileges. Here's my MSDN thread!
I will add this here in case someone will be as lucky as me.
When reviewing the sp_who2 list of processes note the processes that run not only for the effected database but also for master. In my case the issue that was blocking the database was related to a stored procedure that started a xp_cmdshell.
Check if you have any processes in KILL/RollBack state for master database
SELECT *
FROM sys.sysprocesses
WHERE cmd = 'KILLED/ROLLBACK'
If you have the same issue, just the KILL command will probably not help.
You can restarted the SQL server, or better way is to find the cmd.exe under windows processes on SQL server OS and kill it.
In SQL Management Studio, go to Security -> Logins and double click your Login. Choose Server Roles from the left column, and verify that sysadmin is checked.
In my case, I was logged in on an account without that privilege.
HTH!
Killing the process ID worked nicely for me.
When running "EXEC sp_who2" Command over a new query window... and filter the results for the "busy" database , Killing the processes with "KILL " command managed to do the trick. After that all worked again.
I know this is an old post but I recently ran into a very similar problem. Unfortunately I wasn't able to use any of the alter database commands because an exclusive lock couldn't be placed. But I was never able to find an open connection to the db. I eventually had to forcefully delete the health state of the database to force it into a restoring state instead of in recovery.
In rare cases (e.g., after a heavy transaction is commited) a running CHECKPOINT system process holding a FILE lock on the database file prevents transition to MULTI_USER mode.
In my scenario, there was no process blocking the database under sp_who2. However, we discovered because the database is much larger than our other databases that pending processes were still running which is why the database under the availability group still displayed as red/offline after we tried to 'resume data'by right clicking the paused database.
To check if you still have processes running just execute this command:
select percent complete from sys.dm_exec_requests
where percent_complete > 0
How can I kill or rollback, uncommitted transaction?
I am listing my active transactions with the following sql:
SELECT * FROM sys.dm_tran_session_transactions
My result is:
session_id transaction_id transaction_descriptor enlist_count is_user_transaction is_local is_enlisted is_bound
----------------------------------------------------------------------------------------------------------------------
54 117260 0x0100000036000000 0 1 1 0 0
I dont want to kill the session (54)...
Thanks all
To clear all transaction, Use this only as a temp solution
ALTER DATABASE DatabaseName
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE;
ALTER DATABASE DatabaseName
SET MULTI_USER;
refer this site for more info
Points to check - it also rollbacks committed transactions
You can't kill/rollback a transaction from another session without killing the owner session.
I think, allowing to kill/rollback a transaction from another user's session means many design and security rule violations because it requires entering another user session (in the context of the current sql server engine design). That's probably why it is not implemented.
