经典 ASP 3.0 从记录集创建数组 [英] Classic ASP 3.0 Create Array from a Recordset

问题描述

我正在尝试修复 ASP Classic 应用程序，当我尝试从 Recordset 对象创建数组时.但是我无法让它正常工作.

I'm trying to fix an ASP Classic app and when I try to create an array from a Recordset Object. However I Can't get it to work correctly.

这段代码给了我一条记录(最后一条)，但据我所知是正确的:

This code gives me a single record (the last one), but as far as I can see it is correct:

Dim Products
Dim Products_cmd
Dim Products_numRows

Set Products_cmd = Server.CreateObject ("ADODB.Command")
Products_cmd.ActiveConnection = Conn
Products_cmd.CommandText = "SELECT prod_id, prod_description FROM dbo.products ORDER BY prod_description ASC" 
Products_cmd.Prepared = true

Set Products = Products_cmd.Execute
Products_numRows = 0

Dim arrProducts()
arrProducts = Products.GetRows()

使用此代码给我一个下标超出范围:'UBound'

Using this code gives me an "Subscript out of range: 'UBound'

Dim Products
Dim Products_cmd
Dim Products_numRows

Set Products_cmd = Server.CreateObject ("ADODB.Command")
Products_cmd.ActiveConnection = Conn
Products_cmd.CommandText = "SELECT prod_id, prod_description FROM dbo.products ORDER BY prod_description ASC" 
Products_cmd.Prepared = true

Set Products = Products_cmd.Execute
Products_numRows = 0
Dim arrProducts()
Dim counter

For counter = 0 to Products.RecordCount - 1
    ReDim Preserve arrProducts(counter,2)
    arrProducts(counter,0) = Products.Fields.Item("prod_id").Value
    arrProducts(counter,1) = Products.Fields.Item("prod_description").Value
    Products.MoveNext
Next
Response.Write(Str(UBound(arrProducts)))

任何想法将不胜感激...

Any ideas would be GREATLY appreciated...

推荐答案

你的差不多了，问题是GetRows()返回的是一个二维数组，需要告诉Ubound 你想要什么尺寸.

Your are almost there, the problem is that GetRows() returns a 2 dimensional array, and you need to tell Ubound what dimension do you want.

工作代码:

Dim Products
Dim Products_cmd
Dim Products_numRows

Set Products_cmd = Server.CreateObject ("ADODB.Command")
Products_cmd.ActiveConnection = Conn
Products_cmd.CommandText = "SELECT prod_id, prod_description FROM dbo.products ORDER BY prod_description ASC" 
Products_cmd.Prepared = true

Set Products = Products_cmd.Execute

Dim arrProducts
arrProducts = Products.GetRows()

dim i
response.write "<table>"
For i = 0 to ubound(arrProducts, 2)
   response.write "<tr>"
   response.write("<td>" + trim(i+1))
   response.write("<td>" + trim(arrProducts(0,i)))
   response.write("<td>" + trim(arrProducts(1,i)))
next
response.write "</table>"
%>
