纯编码如何实现Access数据库的建立或压缩(4)
Set Ca = Nothing CreateDBfile = True End If End function Public function CompactDatabase(byVal dbFileName,byVal DbVer,byVal SavePath) 压缩 数据库 文件 0 为access 97 1 为access 2000 On Error resume next If Right(SavePath,1) Or Right(SavePat
CreateDBfile = True
End If
End function
Public function CompactDatabase(byVal dbFileName,byVal DbVer,byVal SavePath)
’压缩数据库文件
’0 为access 97
’1 为access 2000
On Error resume next
If Right(SavePath,1)"" Or Right(SavePath,1)"/" Then SavePath = Trim(SavePath) & ""
If Left(dbFileName,1)="" Or Left(dbFileName,1)="/" Then dbFileName = Trim(Mid(dbFileName,2,Len(dbFileName)))
If DbExists(SavePath & dbFileName) Then
Response.Write ("对不起,该数据库已经存在!")
CompactDatabase = False
Else
Dim Cd
Set Cd =Server.CreateObject("JRO.JetEngine")
If Err.number0 Then
Response.Write ("无法压缩,请检查错误信息
" & Err.number & "
" & Err.Description)
Err.Clear
Exit function
End If
If DbVer=0 Then
call Cd.CompactDatabase("Provider=Microsoft.Jet.OLEDB.3.51;Data Source=" & SavePath & dbFileName,"Provider=Microsoft.Jet.OLEDB.3.51;Data
Source=" & SavePath & dbFileName & ".bak.mdb;Jet OLEDB;Encrypt Database=True")
Else
call Cd.CompactDatabase("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
SavePath & dbFileName,"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &
SavePath & dbFileName & ".bak.mdb;Jet OLEDB;Encrypt Database=True")
End If
’删除旧的数据库文件
call DeleteFile(SavePath & dbFileName)
’将压缩后的数据库文件还原
call RenameFile(SavePath & dbFileName & ".bak.mdb",SavePath & dbFileName)
Set Cd = False
CompactDatabase = True
End If
