大家来看看 为什么这段代码无法删除数据记录
<%
        Dim   ids
        ids   =   Request.QueryString( "id ")
                If   Not   isEmpty(ids)   Then
                          If   inStr(ids, ", ")> 0   Then
                                  Dim   idArr
                                  idArr=split(ids)
                                  Dim   id
                                  For   i   =   0   To   ubound(idarr)
                    id=cLng(idarr(i))
                    sql   =   "DELETE   FROM   BOOK   WHERE   ID   =   ' "   &   id   & " ' "
      conn.Execute(sql)
                Next
        Else
                                  sql   =   "DELETE   FROM   BOOK   WHERE   ID   =   ' "   &   ids   & " ' "
                conn.Execute(sql)       //第38行
        End   If
    End   If

sql   =   "DELETE   FROM   BOOK   WHERE   ID   IN   ( "   &   ids   &   ") "
conn.Execute(sql)
%>


运行之后,提示:
Microsoft   JET   Database   Engine   '80040e07 '  
标准表达式中数据类型不匹配。
\bookDelt.asp,   line   38

------解决方案--------------------
<%
Dim ids
ids = Request.QueryString( "id ")
If Not isEmpty(ids) Then
If inStr(ids, ", ")> 0 Then
Dim idArr
idArr=split(ids)
Dim id
For i = 0 To ubound(idarr)
id=cLng(idarr(i))
sql = "DELETE FROM BOOK WHERE ID = " & id conn.Execute(sql)
Next
Else
sql = "DELETE FROM BOOK WHERE ID = " & ids 'ID 为整型不用引号
conn.Execute(sql)
End If
End If

sql = "DELETE FROM BOOK WHERE ID IN ( " & ids & ") "
conn.Execute(sql)
%>


------解决方案--------------------
sql = "DELETE FROM BOOK WHERE ID = " & id & " "
