MS Access select between two dates?

Question

I have searched, but all results didn\'t help me to understand.

I need to select names of people who are 18-23 years old. So my try was:

WHERE ((People.         


        

Answer 1

For a true solution, you need to use DateAdd and a function like this:

Public Function AgeSimple( _
  ByVal datDateOfBirth As Date) _
  As Integer

' Returns the difference in full years from datDateOfBirth to current date.
'
' Calculates correctly for:
'   leap years
'   dates of 29. February
'   date/time values with embedded time values
'
' DateAdd() is used for check for month end of February as it correctly
' returns Feb. 28. when adding a count of years to dates of Feb. 29.
' when the resulting year is a common year.
' After an idea of Markus G. Fischer.

  Dim datToday  As Date
  Dim intAge    As Integer
  Dim intYears  As Integer

  datToday = Date
  ' Find difference in calendar years.
  intYears = DateDiff("yyyy", datDateOfBirth, datToday)
  If intYears > 0 Then
    ' Decrease by 1 if current date is earlier than birthday of current year
    ' using DateDiff to ignore a time portion of datDateOfBirth.
    intAge = intYears - Abs(DateDiff("d", datToday, DateAdd("yyyy", intYears, datDateOfBirth)) > 0)
  End If

  AgeSimple = intAge

End Function

Then your query will have this where clause:

WHERE AgeSimple(People.Birth) Between 18 And 23

Finally solved it by simple

WHERE ((People.Birth) Between (Now()- 365*18) And (Now()-365*23))
