根据FK从SQLAlchemy中的两个表中选择数据

Question

我有两张桌子。表1的product_id是表2的FK。

在SQLAlchemy中，我如何从表1中选择特定的user_id的product_id，并从表2中检索其product_description？

Table 1
user_id, product_id
1           2
2           5
3           2

Table 2
product_id, product_description
1               some product_description
2               some product_description
3               some product_description
4               some product_description

If (Not (IsNull(path))) Then
    Set cn = New ADODB.Connection
    cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & path & ";"
    Set rs = New ADODB.Recordset
    rs.Open "BCIImport", cn, adOpenKeyset, adLockOptimistic, adCmdTable
On Error Resume Next
    Do While Len(Range("B" & r).Formula) > 0
        With rs
            If Not rs.BOF Then
                rs.MoveFirst
            End If

            If (Range("B" & r).Interior.Color = RGB(0, 255, 255)) Then
                .AddNew
                .Fields("LocationID") = Range("B" & r).Value
                .Fields("Priority1") = Range("C" & r).Value
                .Fields("Priority2") = Range("D" & r).Value
                .Update
            End If
        End With
        r = r + 1 'advances to next row
    Loop
    rs.Close
    cn.Close
    Set rs = Nothing
    Set cn = Nothing
End If
