Question

我目前有两个50k +行的文件。它们都包含订单代码。在一个文件中是正确的（＆＃34; AQ列＆＃34;，7），另一个文件在C列中。我想匹配订单代码，并比较值是否相同。此外，在第二个文件中，应该检查不同的列以查看是否存在匹配的字符串＆＃34; SETTLED＆＃34;因为该文件中有重复的订单代码。

我已经尝试了一些方法，我在下面粘贴一个效率不高的方法，以便我想要解决的问题要清楚。 revnW和Wpay是两种不同的工作簿

DesLRow = revnW.Sheets(1).Cells(Rows.Count, 1).End(xlUp).Row
SrcLRow = wPay.Sheets(1).Cells(Rows.Count, 1).End(xlUp).Row

For i = 2 to DesLrow
 for j = 3 to srcLrow
  If right(revnW.Sheets(1).Cells(i,43).text, 7) = wPay.Sheets(1).Cells(j,3).text And_
 Instr(wPay.Sheets(1).Cells(j,5).text, "SETTLED") And value <> value 2 (pseudo code) Then


Do stuff (get transaction number, and some other things)
      exit for   
      next j
Next i

我知道这段代码效率不高，我试图将列加载到数组中，但后来我只能比较一列，而不是值等。

非常感谢任何帮助。

我会用一些SQL处理数据。这是一个在第三个表中连接两个表的示例：

var express = require('express');
var app = express();

// Users routes
var users = require('./routes/users');

// Tell our app to use the Users routes defined in ./routes/users.js
app.use('/users', users);

app.listen(process.env.PORT || 3000, function() {
  console.log('listening');
});

未经测试，但应该给你一个起点：

Sub Tester()

    Dim desLRow As Long, srcLRow As Long
    Dim dictDest As Object, dictSrc As Object

    With revnW.Sheets(1)
       Set dictDest = RowMap(.Range(.Cells(2, 43), .Cells(.Rows.Count, 43).End(xlUp)), 7)
    End With
    With wPay.Sheets(1)
       Set dictSrc = RowMap(.Range(.Cells(3, 3), .Cells(.Rows.Count, 3).End(xlUp)))
    End With

    For Each k In dictDest.keys
        If dictSrc.exists(k) Then

            'do the rest of your checks here....

            Debug.Print "Match between Dest " & dictDest(k).Address & " and " & _
                        dictSrc(k).Address
        End If
    Next k

End Sub

这是“地图”功能：

'Get a "map" of row keys to the
'    rows where they are located (just maps the first cell in each row)
' "rng" is the range to be mapped
' "numright" -  pass a number if you just want a part of the value to be mapped
Function RowMap(rng As Range, Optional numRight As Long = 0)
    Dim rv, nr As Long, nc As Long, r As Long, c As Long
    Dim k, data

    Set rv = CreateObject("scripting.dictionary")

    data = rng.Value
    For r = 1 To UBound(data, 1)
        k = data(r, 1)
        If numRight > 0 Then k = Right(k, numRight)
        If rv.exists(k) Then
            Set rv(k) = Application.Union(rv(k), rng.Columns(1).Cells(r))
        Else
            rv.Add k, rng.Columns(1).Cells(r)
        End If
    Next r
    Set RowMap = rv
End Function
