注意:很多时候不能直接还原,因为数据不是独占打开.可能用到下面的过程
1: --Kill掉访问某个数据库的连接
2: CREATE PROC KillSpid(@DBName varchar)
3: AS

5: DECLARE @SQL varchar
6: DECLARE @SPID int
7: SET @SQL=\'DECLARE CurrentID CURSOR FOR
8: SELECT spid FROM sysprocesses WHERE dbid=db_id(\'\'\'+@DBName+\'\'\') \'
9: FETCH NEXT FROM CurrentID INTO @SPID
10: WHILE @@FETCH_STATUS <>-1
11: BEGIN
12: exec(\'KILL \'+@SPID)
13: FETCH NEXT FROM CurrentID INTO @SPID
14: END
15: CLOSE CurrentID
16: DEALLOCATE CurrentID
17: END
当kill掉用户后最好使用单用户操作数据库
SP_DBOPTION @DBName,\'single user\',\'true\'
