asp 自定义分段函数 计算第N名成绩

asp 自定义分段函数 计算第N名成绩：

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
