這篇文章主要介紹了ASP在線壓縮access數(shù)據(jù)庫的方法,本文給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

ASP在線壓縮ACCESS數(shù)據(jù)庫原理很簡(jiǎn)單：利用JRO.JetEngine的壓縮功能建立一個(gè)新的數(shù)據(jù)庫文件，然后把原來的刪掉、替換！既然這樣，壓縮程序只需幾行就ok了！

把下面的代碼保存為**.asp，數(shù)據(jù)庫文件（db.md）放在相同目錄下，執(zhí)行asp搞定！

<%
oldDB = server.mappath("db.mdb") '更改數(shù)據(jù)庫地址
newDB = server.mappath("db_new.mdb") '生成臨時(shí)文件
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
Set Engine = Server.CreateObject("JRO.JetEngine")
prov = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
Engine.CompactDatabase prov & OldDB, prov & newDB
set Engine = nothing
FSO.DeleteFile oldDB '刪除臨時(shí)文件
FSO.MoveFile newDB, oldDB
set FSO = Nothing
response.write "OK"
%>

下面是一個(gè)ASP在線壓縮ACCESS數(shù)據(jù)庫的封裝函數(shù)

Function CompactDB(dbPath, boolIs97)
Dim fso, Engine, strDBPath
strDBPath = left(dbPath,instrrev(DBPath,"\"))
Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FileExists(dbPath) Then
Set Engine = CreateObject("JRO.JetEngine")
On Error Resume Next
If boolIs97 = "True" Then
Engine.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & dbpath, _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDBPath & "temp.mdb;" _
& "Jet OLEDB:Engine Type=" & JET_3X
Else
Engine.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & dbpath, _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDBPath & "temp.mdb"
End If
 
If Err Then
response.write "<script LANGUAGE='javascript'>alert('無法識(shí)別數(shù)據(jù)庫類型.');history.go(-1);</script>"
response.end
end if
fso.CopyFile strDBPath & "temp.mdb",dbpath
fso.DeleteFile(strDBPath & "temp.mdb")
Set fso = nothing
Set Engine = nothing
CompactDB = "<script>alert('壓縮成功！');javascript:history.go(-1);</script>"
Else
CompactDB = "<script>alert('找不到數(shù)據(jù)庫！\n請(qǐng)檢查數(shù)據(jù)庫路徑是否輸入錯(cuò)誤！');history.back();</script>"
End If
End Function
