sp_detach_db

Hi,
i need to detach database using osql, even if it's in use.
when detaching database from EM, window appears with option to clear current connection.
how can this be done using T-sql?

You could also do it as follows

alter database <dbname> set single_user with rollback immediate

<....... do your stuff here ..........>
-- also make sure to issue a "use master" before calling sp_detach

alter database <dbname> set multi_user with rollback immediate

Use the following SQL syntax.

sp_detach_db

For example,

EXEC sp_detach_db 'pubs', 'true'

This statement detatches the pubs database with the option to not 'update statistics' after detaching the database

for killing use

DECLARE @Proc varchar(30)

DECLARE Processes CURSOR FOR
SELECT prc.spid
FROM master.dbo.sysprocesses prc
INNER JOIN master.dbo.sysdatabases db
      ON prc.dbid = db.dbid
WHERE
      db.name = ' HERE DB NAME'

OPEN Processes
FETCH NEXT FROM Processes INTO @Proc

WHILE @@FETCH_STATUS = 0
BEGIN
      SET @Proc = 'KILL ' + @Proc
      EXEC(@Proc)
      FETCH NEXT FROM Processes INTO @Proc
END

CLOSE Processes
DEALLOCATE Processes

This is what the SQL Server also internally do when you execute "clear" command..so, to script it..it is like this... (Example for PUBS database)
But, unless it is very much required. I do not recommend to query the system tables directly.


use master
GO

declare @spid int

declare curprocesses cursor
for select spid from master.dbo.sysprocesses WHERE (dbid = (SELECT dbid FROM master.dbo.sysdatabases WHERE (name = 'pubs')))

open curprocesses
fetch next from curprocesses into @spid

while (@@fetch_status = 0)
  begin
   exec ('kill ' + @spid)
   fetch next from curprocesses into @spid
  end

close curprocesses
deallocate curprocesses

EXEC sp_detach_db 'pubs'
