在线压缩Access数据库
时间:2022-06-30 10:23:38 编辑:袖梨 来源:一聚教程网
While working on BuildDB/Buildapp online Demo, I developed a little function that will compact Access databases over the web. Here's a "no-frills" page that'll compact the databases for you.
One problem with Access databases is that "holes" are created when records are deleted, making the database fluffy and bloated. Compacting the database makes it lean and efficient again.
Note: This function/page can easily be combined with the Buildapp front end file navigation and search pages (Installment II), to create an application that'll make it easy to handle this formerly troublesome chore for all the databases on your machine/web site..
++++++++++++ Begin Compact.asp +++++++++++++++++++++++++++++

option explicit
Const JET_3X = 4
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")
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
fso.CopyFile strDBPath & "temp.mdb",dbpath
fso.DeleteFile(strDBPath & "temp.mdb")
Set fso = nothing
Set Engine = nothing
CompactDB = "Your database, " & dbpath & ", has been Compacted" & vbCrLf
Else
CompactDB = "The database name or path has not been found. Try Again" & vbCrLf
