自动清除替换ACCESS(MDB)数据库的日文字符的ASP代码

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

Set objRS=Nothing

End Function
