ASP读取数据库中数据到数组的类

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
