How do I kill connections to Azure SQL database if I can't access it?
This issue was caused by Azure automated backups failing to end sessions correctly. None of the other answers worked as they all require you to be able to connect to the database, and I was unable to do this. I ended up speaking on the phone to Microsoft Support for some hours, during which they were also unable to connect to the database for the same reason.
The resolution, from their end, was to migrate the database to a new node, which is not something that Azure users can do, so if you encounter this level of issue, really the best (and only) thing to do is to contact Microsoft support ASAP.
I do recommend trying out some of the other suggestions here first, but without the ability to make any connections you will be stuck.
Because this occurred during the process of upgrading a database on Azure, we implemented a procedure of disabling automated backups before upgrading databases as a precaution, and the problem has not reoccurred for us.
kill Azure SQL DB sessions
I don't recommend killing sessions with out knowing what they are doing first..
so step1 would be to understand their current state..
from sys.sysprocesses sp
The above dmv gives the state of all sessions and you can see if any of them are blocked ,if they are blocked, you can check the blocking session and try knowing why it is blocked by inputting blocking session spid like below
dbcc inputbuffer(blocking session spid)
With this you can try checking if the hung state you are experiencing is due to blocking.You can try resolving the blocking or try killing blocking spid
IF you don't see any blocking,but if think those sessions are hung,try running below dmv to see last read,write state..by this way you can check if the session is really doing some work
Try checking what the session is about before killing it(using input buffer..because, some may be internal processes like
How do I disconnect open connections to an Azure SQL Managed Instance?
In RESTORE FROM URL in Managed Instance you can't even replace existing databases.
So either drop or rename the database before the RESTORE. Both
DROP DATABASE MyDb and
ALTER DATABASE MyDb MODIFY NAME = MyDb_old will kill existing connections to the database.
Alternatively you can use the Managed Point-in-Time Restore to restore an existing database to a previous point-in-time.
