restore database 被恢复的数据库名 from disk = ' 备份文件路径 ' ;
Alter Database 被恢复的数据库名 Set OnLine With rollback Immediate;
/////////////////////
string sql = " Alter Database db Set Offline with Rollback immediate; " ; // db 是要备份的数据库名
sql += " restore database db from disk = ' " ;
sql += Server.MapPath( "" ).ToString() + " \\ " ;
sql += bakname + " ' " ; // bakname 是备份文件名
sql += " Alter Database db Set OnLine With rollback Immediate; " ;
try
{
连接 master 数据库 ;
执行 sql 语句;
Response.Write("<script language=javascript>alert('数据恢复成功!');</script>");
}
catch (Exception ex)
{
Response.Write("<script language=javascript>alert('数据恢复失败!');</script>");
this.Label2.Text = ex.ToString();
}
备份数据库:
关键字:backup database 被备份的数据库名 to disk = ' 备份文件路径 ' ;
//////////////////////
string sql = " backup database db to disk = ' " + Server.MapPath( "" ).ToString() + " \\ "
+ bakname // 备份文件名
