数据库还原,高分求救!

[guge]

dm.ADOCon.Connected:=false;
sqls:='use master restore database exam from disk='''+ss+''' with REPLACE ';
dm.DBSetQ.ConnectionString:=MainFrm.cons;
dm.DBSetQ.Close;
dm.DBSetQ.SQL.Clear;
dm.DBSetQ.SQL.Add(sqls);
dm.DBSetQ.ExecSQL;
语句能够执行，但执行的结果是数据库没任何改变。
在sql server的事件跟踪器中显示Reads,Writes项均比手工还原的数值小！
不知是何原因，请教各位有没遇到类似情形！

其中的SS是还原的文件名!

怎么连个进来看一下的都没有啊!

转贴:
当我恢复时出错：
with query1 do
begin
close;
sql.Clear;
sql.Add(format('RESTORE DATABASE tushu FROM DISK=''%s''',[gn]));
execsql;

错误提示为：
因为数据库正在使用，未能获得数据库的排它访问权
请问该怎么做？？？
在查询分析器中运行
use master
go

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_killspid]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[p_killspid]
GO

create proc p_killspid
@dbname sysname--要关闭进程的数据库名
as
declare @s nvarchar(1000)
declare tb cursor local for
select s='kill '+cast(spid as varchar)
from master..sysprocesses
where dbid=db_id(@dbname)

open tb
fetch next from tb into @s
while @@fetch_status=0
begin
exec(@s)
fetch next from tb into @s
end
close tb
deallocate tb
go

procedure TForm3.Button2Click(Sender: TObject);
begin
if opendialog1.Execute then
begin
adoquery1.SQL.Text:='use master;exec p_killspid mydatabase;Restore database madatabase From disk='''+opendialog1.FileName+''';Use mydatabase';
adoquery1.ExecSQL;
application.MessageBox('数据库完成恢复','提示',MB_OK);
end;
end;

/*
我也是这么写的
（还原过程中不能有任何程序访问数据库）
还原后强制退出软件，再登陆
如果没有其他程序访问数据库的话，一般能还原成功
*/
ExecuteSql('use master');
ExecuteSql(Format('RESTORE DATABASE %s FROM DISK =''%s'' with replace',[g_sDefaultdb,FileName]));

fmMain.bsSkinMessage1.MessageDlg('数据库恢复已完成，请重新启动程序!',mtInformation,[mbOK],0);
Application.Terminate;
Abort;

在master里创建存储过程

create proc p_killspid
@dbname sysname--要关闭进程的数据库名
as
declare @s nvarchar(1000)
declare tb cursor local for
select s='kill '+cast(spid as varchar)
from master..sysprocesses
where dbid=db_id(@dbname)

open tb
fetch next from tb into @s
while @@fetch_status=0
begin
exec(@s)
fetch next from tb into @s
end
close tb
deallocate tb
go

以上这个最重要，没有这个不可以换原的


procedure TForm23.Button2Click(Sender: TObject);
begin
if opendialog1.Execute then
begin
adoquery1.SQL.Text:='use master;exec p_killspid mydatabase;Restore database madatabase From disk='''+opendialog1.FileName+''';Use mydatabase';
adoquery1.ExecSQL;
application.MessageBox('数据库完成恢复','警告',MB_OK);
end;
end;


我就是这么恢复的，绝对可行，不行的话大概是你哪个环节没处理好

谢谢以上各位的热心回复,关键我的程序是能执行,并没报错,只是执行完了的结果是数据库并没有任何改变.不知是何原因!
