variables - 如何使用 VBA 遍历 MS Access 记录集并将变量分配给结果？

Question

我的 VBA 很生疏，我似乎在画一个空白。如果重要的话，我正在使用 MS Access 2010。

我有一个查询的结果，它返回两个字段(Field1 是文本，Field2 是 double )和五个记录，我想根据 Field1 中的内容将 Field2 值分配给五个不同的变量。对我来说，这是某种 case 语句 - 我将如何在记录集的 VBA 中执行此操作？

  Private Sub test()

  Dim myRS As DAO.Recordset
  Dim db As Database
  Dim strSQL As String
  Dim v1, v2, v3, v4, v5 As Double

  ' Pretend strSQL is a different query that gives five records

  Set dbs = CurrentDb
  strSQL = "SELECT Field1, BigNumber FROM tmp1"
  Set myRS = dbs.OpenRecordset(strSQL)

  Do While Not myRS.EOF
      v1 = ?         ' I want v1 = Field2 when Field1="A"
      v2 = ?         ' I want v2 = Field2 when Field1="B"
      v3 = ?         ' I want v3 = Field2 when Field1="C"
      v4 = ?         ' I want v4 = Field2 when Field1="D"
      v5 = ?         ' I want v5 = Field2 when Field1="E"
  Loop

  End Sub

非常感谢 !

Private Sub test()

Dim myRS As DAO!Recordset
Dim db As Database
Dim strSQL As String
Dim v1, v2, v3, v4, v5 As Double

' Pretend strSQL is a different query that gives five records

Set dbs = CurrentDb
strSQL = "SELECT Field1, BigNumber FROM tmp1"
Set myRS = dbs!OpenRecordset(strSQL)

Do While Not myRS!EOF
    Select Case myRS.Fields(0)
    Case "A"
        v1 = myRS.Fields(1)
    Case "B"
        v2 = myRS.Fields(1)
    Case "C"
        v3 = myRS.Fields(1)
    Case "D"
        v4 = myRS.Fields(1)
    Case "E"
        v5 = myRS.Fields(1)
    End Select
Loop
