對(duì)于上傳的數(shù)據(jù)庫中的文件有的時(shí)候需要保存成硬盤上的文件，下面的代碼以ACCESS數(shù)據(jù)庫為例,演示怎樣通過Adodb.Stream將文件保存到硬盤

表：Demo的結(jié)構(gòu)
=======================================
id： 自動(dòng)編號(hào)
filename：文本
data: OLE 對(duì)象

Dim Conn,ConnStr,Rs,Sql,MyStream

ConnStr="DBQ=" + Server.Mappath("Demo.mdb") + ";DRIVER={Microsoft Access Driver (*.mdb)};"

Set Conn = Server.CreateObject("Adodb.Connection")

Conn.Open ConnStr

Sql = "select * from demo where id=1"

Set Rs = Server.CreateObject("Adodb.RecordSet")

Rs.Open Sql,Conn,1,3

Set MyStream=Server.CreateObject("Adodb.Stream")

MyStream.Type = 1

MyStream.Open

MyStream.Write Rs("data").GetChunk(rs("data").ActualSize-78)

MyStream.SaveToFile "c:\" & Rs("fileName")

Rs.Close

Set Rs = Nothing

Conn.Close

Set Conn = Nothing
