Fetching A Record From The Database Within A Function.

Can I do something like this in RS -

I would like to call a function in a calculated field like
=code.GetNHW(Fields!id1.Value,Fields!date1.Value)
where the GetNHW() function would return a double value based on some conditions-
The code I would like to write in Code window-
Public Function GetNHW(ByVal ID As Integer, ByVal attDate As Date) As Double
Dim dsDTConfig As New DataSet
Dim NHW As Double
dsDTConfig = GetDS("tblEmployee_DailyTimingsConfig", "id=" & ID & " and '" & attDate & "' between configStartDate and configExpiryDate", False)
If dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = True Then
NHW = 0.01
ElseIf dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = False Then
NHW = 0.05
End If
Return NHW
End Function
What I am looking for is - I would want to get the record(dataset) within the function from the database
and based on the values got, I would check few conditions and calculate NHW.
