無組件的資料庫的備份與還原

作者：Eve Cole 更新時間：2009-06-23 17:05:34

看過資料庫的備份與還原。大多數都是用組件來完成的。其實可透過sql語句來完成。
由於時間關係，未對參數進行驗證和介面美化。代碼僅供參考。
共4個檔案：下載位址： function rec(rs,sql)
set rs = server.CreateObject("ADODB.Recordset")
rs.Activeconnection = conn
rs.Source = sql
rs.CursorType = 0
rs.Cursorlocation = 3
rs.LockType = 1
rs.Open
if rs.eof and rs.bof then
rec= false
else
rec= true
end if
end function
function cmd(sql)
dim cmd1
set cmd1 = server.CreateObject("ADODB.Command")
cmd1.ActiveConnection = conn
cmd1.CommandText = sql
cmd1.CommandType = 1
cmd1.CommandTimeout = 0
cmd1.Prepared = true
cmd1.Execute()
end function
function cdb(rs)
rs.close()
set rs=nothing
end function
%>
dev.asp

<%
if request("AddDev") <> "" then
sql="select name,phyname from master..sysdevices where status=16 and name='"&request("devname")&"'"
rec chk,sql
if chk.eof and chk.bof then
sql = "sp_addumpdevice 'disk','"&request("devname")&"','"&request("phyname")&"'"
cmd sql
response.Write "<script language=javascript>window.location=reload;</script>"
else
response.Write "<script language=javascript>alert('資料庫中已存在"&request("devname")&"裝置！');window.location='cmd.asp';</script>"
end if
end if
if request("deldev") <> "" then
sql = "sp_dropdevice '"&request("devname")&"'"
cmd sql
response.Write "<script language=javascript>window.location=reload;</script>"
end if
rec li,"select name,phyname from master..sysdevices where status=16"
if li.eof and li.bof then
response.Write "<font color=#ff0000>請新備份設備用來備份還原資料庫</font>"
