我们都知道ACCESS是ASP的亲密伙伴。因为两种最简单的东西碰在一起总能迸发出火花。
然而，当我们过滤不严格的时候经常出现日文字符，这个时候搜索之后就会出现日文溢出。
此时我们通常能想到的想法是找一个exe程序，把这个问题解决掉。我原来用C#写过这样一个类似的程序。
Google里面应该能找到我以前写的那个。就不说了。
后来某一天，我发现ASP就能实现。我当时真的觉得自己太屎了。
不过ASP的这种方法很不好。容易造成系统崩溃（如果数据库大）。
所以只是写在这里。算是抛砖引玉。
'下面我解释一下下：
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
'遍历，看看有没有日文，如果有，就溢出了，随便搜索一个东西就行了。搜什么无所谓。因为是遍历ACCESS只要指针移动到日文就溢出。
objConn.Execute("SELECT * FROM [blog_Comment] WHERE comm_ID="&objRS("comm_ID")&" AND [comm_Content] LIKE '%URL%'")
If Err.Number=-2147217900 Then
'因为是on err继续 所以这里找到溢出的错误代码，这个是自己debug出来的，实际上不是从什么地方找的。
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")&" ")
'这个就是把日文替换一下，思路是不是很巧妙。恩。不过数据库庞大的化，反复溢出就会很出问题的。内存宝宝会哭的。
Err.Clear
End If
objRS.MoveNext
Next
End If
objRS.Close
