这样所有的账户都改为dbo，即可。
下一步，把脚本命名为sqlscript.txt, 最好不要叫sqlscript.sql，下面会介绍。
然后通过ftp把脚本放到网站的空间。
编写脚本，例如命名为runsql.aspx ,然后运行该脚本即可还原数据库

}
// Execute T-SQL against the target database
cmd.CommandText = sb.ToString();
cmd.CommandTimeout = timeout;
cmd.ExecuteNonQuery();
}
}
this.Response.Write("T-SQL file executed successfully");
}
catch (Exception ex)
{
this.Response.Write(String.Format("An error occured: {0}", ex.ToString()));
}
finally
{
// Close out the connection
//
if (conn != null)
{
try
{
conn.Close();
conn.Dispose();
}
catch (Exception e)
{
this.Response.Write(String.Format(@"Could not close the connection. Error was {0}", e.ToString()));
}
}
}

需要注意
string fileUrl = @"http://www.sohu.com/sqlscript.txt";
是用户脚本地址，因为很多空间禁止获取sql，所以，改成这样
string fileUrl = @"http://www.sohu.com/sqlscript.sql";
系统可能无法运行。
这样，就完成了数据库转移。
