如何用if语言判断查询的数据？

下面代码是我实际中的一个运用，供你参考：

目的是用于判断：当表[DN Summary]中[Total Plts]字段的值为0时，将Printed的字段值设为True。

Sub Count0PltasPrinted()
Dim Rst As Recordset
Dim DNcc As String, LastDN As String
Dim Plts As Currency

    Set Rst = CurrentDb.OpenRecordset("DN Summary")
    Rst.MoveFirst
    LastDN = Rst!DN
    
    Do Until Rst.EOF
        If Int(Rst![Total Plts]) = Rst![Total Plts] And Rst![Total Plts] = 0 Then
           Rst.Edit
           Rst!Printed = True
           Rst.Update
        End If
        Rst.MoveNext
    Loop
    Rst.Close
End Sub
