    To retrieve the month portion of a date do something like (use the month() function:
    Code:
     
     Dim varMonth,varDate
     varDate=#1/2/2009#
     varMonth=month(varDate)
     msgbox varMonth
    You can use the month() function in a query like this:
    Code:
     
     Dim strSQL 
     strSQL="SELECT Table1.someDateField " & _
                " FROM Table1 " & _
                 " WHERE Month([someDateField])=4;"
    Please note that the month function returns an integer corresponding to the month. Therefore april is 4

    This code should work (USING THE MONTH FUNCTION)
    Code:
    sqlstr="SELECT Lecturer.LastName, Items.ItemName, 
        Assignments.Date_of_Request
        FROM Lecturer INNER JOIN 
        (Items INNER JOIN Assignments ON Items.ItemCode = Assignments.ItemCode) 
        ON Lecturer.LectId = Assignments.LectID
        WHERE ((Month([date_of_request])=4));"

    This code should also work (USING THE DATEPART FUNCTION)
    Code:
    sqlstr="SELECT Lecturer.LastName, Items.ItemName, 
        Assignments.Date_of_Request
        FROM Lecturer INNER JOIN 
        (Items INNER JOIN Assignments ON Items.ItemCode = Assignments.ItemCode)
        ON Lecturer.LectId = Assignments.LectID
        WHERE (((DatePart("m",[date_of_request]))=4));"

    Therefore this is the SQL string that should be passed to the database:
    Code:
    sqlstr="SELECT Lecturer.LastName, Items.ItemName, " & _
        " Assignments.Date_of_Request " & _
        " FROM Lecturer INNER JOIN " & _
        " (Items INNER JOIN Assignments ON Items.ItemCode = Assignments.ItemCode) " & _
        " ON Lecturer.LectId = Assignments.LectID " & _
        " WHERE ((Month([date_of_request])=" & 4 & "));"
