Using .Fields() method in Recordsets for calculations.

Using .Fields() method in Recordsets for calculations.

(OP)
Hi all,
I was fiddling around with Recordsets in VBA and I noticed that you can do things like this

CODE --> VBA

"SELECT TOP 1 TotalCost/Amount FROM Sales WHERE [SalesDate] <= " & strDate & _
         " And [ProductID] = " & PID & _
                " ORDER BY [SalesDate] Desc;" 


also

CODE --> vba

With CurrentDb.OpenRecordset(strLastUnitCost)
        If Not (.BOF And .EOF) Then
            fncLastUnitCost = .Fields(4) / .Fields(3) 'Field(4) is Total and Field(3) is Amount
        End If
    End With 

Is it wise to pass those calculations through Recordsets??

RE: Using .Fields() method in Recordsets for calculations.

You can do your calculations in your code, or you can 'delegate' it to your DB:

CODE

Select ...,
Total / Amount As UnitCost, ...
From ... 

And use (calculated) field UnitCost from your recordset smile

Instead of .Fields(4) / .Fields(3) I would rather do this since the order of your fields could/may change if you modify your strLastUnitCost

CODE

With CurrentDb.OpenRecordset(strLastUnitCost)
    If Not (.BOF And .EOF) Then
        fncLastUnitCost = !Total.value / !Amount.value
    End If
End With
