DbPath = "test.mdb"’数据库位置
ConnStr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = " & Server.MapPath(DbPath)
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.open ConnStr
Class Class_Read
Public Arr,Rs,SQL,ArrTR,ArrTD,Page,TotalRead,TotalPage
Public Function Read(SQL,TD,TR,PG)
SQL = Replace(SQL,"’","")
Page= Int(PG)
Set Rs = Server.CreateObject("ADODB.Recordset") : Rs.open SQL,conn,1,1
TotalRead= Rs.RecordCount
If TotalRead>0 Then
If TR>0 Then : Rs.PageSize = TR : Else : TR=TotalRead
If TD>Rs.Fields.Count or TD<1 Then TD = Rs.Fields.Count
If TotalRead Mod TR <>0 Then TotalPage = 1 : End If : TotalPage = TotalPage + Int(TotalRead/TR)
If Page>=TotalPage Then Page=TotalPage : TR = TotalRead-TR*(TotalPage-1)
If Page>1 Then Rs.absolutePage=Page Else Page=1
End If
reDim Arr(TD-1,TR)
For ArrTR = 0 to TR-1 : If Rs.Eof Then Exit For
For ArrTD = 0 to TD-1 : Arr(ArrTD,ArrTR) = Rs(ArrTD) : Next : Rs.MoveNext
Next
ArrTR = ArrTR-1
Rs.Close
Set Rs=Nothing
End Function
End Class
’使用方法
Dim C:Set C = New Class_Read
C.Read ("SQL语句","读取列数","读取行数[既每页显示条数]","当前页数")
Dim i
For i=0 To C.ArrTR
Response.Write "<br>内容:"&C.Arr(0,i)
Next
Response.Write "<br>总记录条数:"&C.TotalRead
Response.Write "<br>总页数 :"&C.TotalPage
Response.Write "<br>当前页 :"&C.Page
Response.Write "<br>当前记录数:"&C.ArrTR+1
