查找所有Access数据库，以及压缩和修复

Question

我试图在目录中查找所有Access数据库，并且每次都压缩和修复而不每次都打开Access。我发现以下文章解释了如何找到它们并将其写入文件： 批处理文件以查找所有Access数据库，但理想情况下，我只想找到它们并压缩而不写文件。

我已经搜索了如何调用/compact命令行功能，但是我不知道如何在找到的数据库上执行该功能。可以.bat写一个文件来做到这一点吗？就像是：

@echo off

"C:\Program Files\Microsoft Office\Office14\MSACCESS.EXE" "C:\Databases\ /s" *.accdb /compact

非常感谢语法的任何帮助。

考虑使用Access专用的CompactRepair方法，该方法可以在VBA中运行（在Access数据库内部或外部，如Excel宏）。需要注意的是，Compact＆Repair实际上会创建一个现有数据库的副本并将其替换为原始数据库，因此需要一些文件处理。

VBA （在MSAccess.exe内部）

Sub RunCompactDBs()
    Dim path As String
    Dim accfile As Variant

    path = "C:\Databases\"
    accfile = Dir(path & "*.accdb", vbDirectory)

    Do While Len(accfile) > 0
        bkfile = Replace(accfile, ".accdb", "_bk.accdb")

        ' CREATE COMPACTED BACKUP
        Application.CompactRepair path & accfile, path & bkfile, False      
        ' COPY TO ORIGINAL PATH
        FileCopy path & bkfile, path & accfile     
        ' DESTROY COMPACTED BACKUP
        Kill path & bkfile                    

        accfile = Dir
    Loop

    Set accApp = Nothing
End Sub

VBA （MSAccess.exe外部）

Sub RunCompactDBs()
    Dim path As String
    Dim accfile As Variant
    Dim accApp As Object

    Set accApp = CreateObject("Access.Application")

    path = "C:\Databases\"
    accfile = Dir(path & "*.accdb", vbDirectory)

    Do While Len(accfile) > 0
        bkfile = Replace(accfile, ".accdb", "_bk.accdb")

        accApp.CompactRepair path & accfile, path & bkfile, False      

        FileCopy path & bkfile, path & accfile                           
        Kill path & bkfile

        accfile = Dir
    Loop

    Set accApp = Nothing        
End Sub

而且没有理由坚持使用VBA。可以与Access对象库建立COM接口的任何语言都可以运行紧凑和修复过程，例如开源语言：

蟒蛇

import os, glob, shutil
import win32com.client

# LAUNCH ACCESS APP
oApp = win32com.client.Dispatch("Access.Application")

for file in glob.glob("C:\\Databases\\*.accdb"):       
    bkfile = file.replace(".accdb", "_bk.accdb")

    oApp.CompactRepair(file, bkfile, False)

    shutil.copyfile(bkfile, file)
    os.remove(bkfile)

oApp = None

[R

library(RDCOMClient)

# LAUNCH ACCESS APP
oApp = COMCreate("Access.Application")

accfiles <- list.files(path="C:\\Databases\\", pattern="\\.accdb", full.names=TRUE)

for (file in accfiles){      
  bkfile = sub(".accdb", "_bk.accdb", file)

  oApp$CompactRepair(file, bkfile, FALSE)

  file.copy(bkfile, file, overwrite = TRUE)
  file.remove(bkfile)      
}

oApp <- NULL
gc()

的PHP

# LAUNCH ACCESS APP
$acc = new COM("Access.Application", NULL, CP_UTF8) or Die ("Did not instantiate Access");

foreach (glob("C:\\Databases\\*.accdb") as $file) {            
    $bkfile = str_replace(".accdb", "_bk.accdb", $file);

    $acc->Application->CompactRepair($file, $bkfile, false);

    copy($bkfile, $file);
    unlink($bkfile);    
}

$acc = NULL;
unset($acc);
