Kill All Connections to an SQL Server Database


Have you ever tried to restore a database using SQL 2008 and the restore failed since the database is in use? In 2005 we used to open “Detach” database and click on the hyperlink of the existing connection which will open the activity monitor and show existing connections.

Currently in SQL 2008 clicking the hyperlink will only display a message informing you that the database is currently in use without redirecting you to the connections page, and you will have to go to the activity monitor, find connections related to your database and kill them one by one.

However, I found an interesting Stored Procedure that kills all database connections Smile

By Henry Huey’s:

Run the script that follows against the master db, then execute the procedure like this:

sp_KillSpidsByDBName MyDBName
CREATE PROCEDURE [dbo].[sp_KillSpidsByDBName] 
@dbname sysname = ''

-- check the input database name
IF DATALENGTH(@dbname) = 0 OR LOWER(@dbname) = 'master' OR LOWER(@dbname) = 'msdb'

DECLARE @killStmts TABLE (stmt VARCHAR(30))

-- find all the SPIDs for the requested db, and create KILL statements
-- for each of them in the @killStmts table variable
FROM master..sysprocesses pr
INNER JOIN master..sysdatabases db
ON pr.dbid = db.dbid
WHERE = @dbname

-- iterate through all the rows in @killStmts, executing each statement
SELECT @rowCtr = COUNT(1) FROM @killStmts
WHILE (@rowCtr > 0)
SELECT TOP(1) @sql = stmt FROM @killStmts
EXEC (@sql)
DELETE @killStmts WHERE stmt = @sql
SELECT @rowCtr = COUNT(1) FROM @killStmts
