自動清除替換ACCESS(MDB)數據庫的日文字符的ASP代碼

我們都知道 access是asp的親密伙伴。因為兩種最簡單的東西碰在一起總能迸發出火花。
然而，當我們過濾不嚴格的時候經常出現日文字符，這個時候搜索之后就會出現日文溢出。
此時我們通常能想到的想法是找一個exe程序，把這個問題解決掉。我原來用C#寫過這樣一個類似的程序。
Google里面應該能找到我以前寫的那個。就不說了。
后來某一天，我發現ASP就能實現。我當時真的覺得自己太屎了。
不過ASP的這種方法很不好。容易造成系統崩潰（如果數據庫大）。
所以只是寫在這里。算是拋磚引玉。

'下面我解釋一下下：
Function TransferJapanDc9CnInDB()

On Error Resume Next
Err.Clear
Dim objRS,i
Set objRS=Server.CreateObject("ADODB.Recordset")
objRS.CursorType = adOpenKeyset
objRS.LockType = adLockReadOnly
objRS.ActiveConnection=objConn
objRS.Source="SELECT * FROM [blog_Comment]"
objRS.Open()

If (Not objRS.bof) And (Not objRS.eof) Then

    For i=1 to objRS.RecordCount
'遍歷，看看有沒有日文，如果有，就溢出了，隨便搜索一個東西就行了。搜什么無所謂。因為是遍歷ACCESS只要指針移動到日文就溢出。
    objConn.Execute("SELECT * FROM [blog_Comment] WHERE comm_ID="&objRS("comm_ID")&" AND [comm_Content] LIKE '%URL%'")
    If Err.Number=-2147217900 Then
'因為是on err繼續所以這里找到溢出的錯誤代碼，這個是自己debug出來的，實際上不是從什么地方找的。
      objConn.Execute("UPDATE [blog_Comment] SET [comm_Content]='"&FilterSQL(Japan2Html(objRS("comm_Content")))&"',[comm_Author]='"&FilterSQL(Japan2Dc9CnHtml(objRS("comm_Author")))&"' WHERE comm_ID="&objRS("comm_ID")&" ")
'這個就是把日文替換一下，思路是不是很巧妙。恩。不過數據庫龐大的化，反復溢出就會很出問題的。內存寶寶會哭的。
      Err.Clear
    End If
    objRS.MoveNext
    Next

End If

objRS.Close
Set objRS=Nothing
