我是靠谱客的博主愉快红牛，最近开发中收集的这篇文章主要介绍asp 自定义分段函数/求第N名成绩，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

Function splitx(strs1 As String, strs2 As String, n As Integer) 

'自定义分段函数 splitx([字符串],"分隔符",第n段) 
Dim groupST() As String 
groupST = Split(strs1, strs2) 
If UBound(groupST) < n - 1 Then 
splitx = 0 
Else 
splitx = groupST(n - 1) 
End If 
End Function 

'/------------------------------------- 
Function minx(KSMC As String, lb As String, kmi As String, n As String) 

'第N名的成绩 minx([考试名称],[类别],[科目],n) 
Dim con As Object 
Dim RS As Object 
Dim stsql As String 
Dim kmf As String 
kmf = Mid(kmi, 1, 1) & "组" 

Set con = Application.CurrentProject.Connection 
Set RS = CreateObject("ADODB.Recordset") 
STRSQL = "SELECT top 1 " & kmi & " as 达标分 FROM 成绩总表 " 
STRSQL = STRSQL + " WHERE ((( " & kmf & " ) <= " & n & ") And ((类别) = '" & lb & "' and 考试名称='" & KSMC & "'))" 
STRSQL = STRSQL + " ORDER BY " & kmi 
RS.Open STRSQL, con, 3, 3 
If RS.EOF Then 
minx = 0 
Else 
minx = RS("达标分") 
End If 
RS.Close 
Set RS = Nothing 
Set con = Nothing 
End Function
