ASP在线压缩ACCESS数据库原理很简单：利用JRO.JetEngine的压缩功能建立一个新的数据库文件，然后把原来的删掉、替换！既然这样，压缩程序只需几行就ok了！
把下面的代码保存为**.asp，数据库文件（db.md）放在相同目录下，执行asp搞定！
<%
oldDB = server.mappath("db.mdb") '更改数据库地址
newDB = server.mappath("db_new.mdb") '生成临时文件
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 '删除临时文件
FSO.MoveFile newDB, oldDB
set FSO = Nothing
response.write "OK"
%>
下面是一个ASP在线压缩ACCESS数据库的封装函数
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('无法识别数据库类型.');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('压缩成功！');javascript:history.go(-1);</script>"
Else
CompactDB = "<script>alert('找不到数据库！\n请检查数据库路径是否输入错误！');history.back();</script>"
End If
End Function
