用ASP.NET还原与恢复SQL Server数据库

asp.net|server|恢复|数据|数据库

需要注意的是还原，还原的时候问题最大了，有别的用户使用数据库的时候无法还原，解决办法就是在MASTER数据库中添加一个存储过程：

create proc killspid (@dbname varchar(20))
as
begin
declare @sql nvarchar(500)
declare @spid int
set @sql='declare getspid cursor for
select spid from sysprocesses where dbid=db_id('''+@dbname+''')'
exec (@sql)
open getspid
fetch next from getspid into @spid
while @@fetch_status<>-1
begin
exec('kill '+@spid)
fetch next from getspid into @spid
end
close getspid
deallocate getspid
end
GO

在还原之前先执行这个存储过程，需要传递dbname，就是你的数据库的名字。下边是类的原代码：（web.config里的数据库连接字符串是constr）

using System;

using System.Configuration;

using System.Data.SqlClient;

using System.Data;

namespace web.base_class

{

/// <summary>

/// DbOper类,主要应用SQLDMO实现对Microsoft SQL Server数据库的备份和恢复

/// <summary>

public class DbOper

{

private string server;

private string uid;

private string pwd;

private string database;

private string conn;

/// <summary>

/// DbOper类的构造函数

/// <summary>

public DbOper()

{

conn=System.Configuration.ConfigurationSettings.AppSettings["constr"].ToString();

server=cut(conn,"server=",";");

uid=cut(conn,"uid=",";");

pwd=cut(conn,"pwd=",";");

database=cut(conn,"database=",";");

}

public string cut(string str,string bg,string ed)

{

string sub;

sub=str.Substring(str.IndexOf(bg)+bg.Length);

sub=sub.Substring(0,sub.IndexOf(";"));

return sub;

}
