超有用。如何将SQL的MODE在MULTI USER和SINGLE USER之间切换

从多用户切换单用户简单，麻烦的是从单用户切换到多用户。可能会总是出现提示有用户连接的情况。

我试过很多其它办法，都遇阻。

以下代码，完美解决。快，准，狠。

推荐。

f you try to access the database which is already in the Single-User mode, you need to close all the connections to the database first, otherwise you will get an error message:


The following query kills the processes accessing the database:

-- Create the sql to kill the active database connections
declare @execSql varchar(1000), @databaseName varchar(100)
-- Set the database name for which to kill the connections
set @databaseName = 'DatabaseName'

set @execSql = ''
select  @execSql = @execSql + 'kill ' + convert(char(10), spid) + ' '
from    master.dbo.sysprocesses
where   db_name(dbid) = @databaseName
and
DBID <> 0
and
spid <> @@spid
exec(@execSql)
GO

Then you should be able to bring the database back to Multi-User mode as usual:

ALTERDATABASE'DatabaseName'SET MULTI_USER
