sql 数据库还原脚本 （kill链接+独占

　　在开发过程中经常会碰到数据库还原，要是sql 连接没完全释放掉，那么还原就会受到阻碍。此脚本就是为了解决这个问题。

USE [master]

GO



/****** Object: StoredProcedure [dbo].[sp_backrecovery] Script Date: 03/12/2014 09:42:38 ******/

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[sp_backrecovery]') AND type in (N'P', N'PC'))

DROP PROCEDURE [dbo].[sp_backrecovery]

GO



USE [master]

GO

/****** Object: StoredProcedure [dbo].[sp_backrecovery] Script Date: 03/12/2014 09:35:55 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

--执行自动还原

/*

exec [master].[dbo].sp_backrecovery 'D:\SQLSERVER\back\uiaa','uiaa_test'

*/

create procedure [dbo].[sp_backrecovery]

(

@Path nvarchar(260),

@dbname varchar(200)

)

as 

begin



if RIGHT(@Path, 1) <> '\'

set @Path = @Path + '\'



declare @back table(

id int identity,

directory nvarchar(260),

depth int,

IsFile bit

)

insert @back exec master.dbo.xp_dirtree 

@path = @path,

@depth = 0,

@file = 1



DECLARE @depth int, @depthMax int

UPDATE @back SET 

directory = @Path + directory

WHERE depth = 1

SELECT 

@depth = 2,

@depthMax = MAX(depth)

FROM @back

WHILE @depth <= @depthMax

BEGIN

UPDATE A SET 

directory = (

SELECT TOP 1 

directory

FROM @back

WHERE depth = @depth - 1

AND IsFile = 0

AND id < A.id

ORDER BY id DESC

) + N'/' + directory

FROM @back A

WHERE depth = @depth

SET @depth= @depth + 1

END



 



--kill 连接

declare @kills table

(

id int identity(1,1),

spid varchar(10)

)

insert into @kills

select spid from sysprocesses where dbid=db_id(@dbname)



declare @i int

declare @icount int

set @i=1

select @icount=count(1) from @kills



while @i<=@icount

begin



declare @spid varchar(10)

select @spid=spid from @kills where id=@i



declare @killsql varchar(200)

set @killsql='kill '+ @spid

exec (@killsql)



set @i=@i+1

end



--完整备份恢复

declare @filepath varchar(1000)

select top 1 @filepath=directory from @back order by directory desc



declare @sql varchar(1000)

set @sql='alter database '+@dbname+' set single_user ' 

exec (@sql)

set @sql=' restore database '+@dbname+' from disk ='''+@filepath+''' with replace,recovery'

exec (@sql)

set @sql=' alter database '+@dbname+' set multi_user '

exec (@sql)

end
