Re: [MS_AccessPros] Re: BEST SIX SUBJECTS

 

Hi Ade,


Is there a StudentID in your table/query? I assume you would like a query that returns for each student their math mark as well as their top five subjects by mark excluding math. 


How would you handle ties?


Can you provide actual table and field names?


Here is a query from the Northwind Orders table that displays the top 3 orders for each customer by Freight:


SELECT Orders.CustomerID, Orders.OrderDate, Orders.Freight
FROM Orders
WHERE (((Orders.OrderDate) In (SELECT TOP 3 O.OrderDate FROM Orders O where O.CustomerID = Orders.CustomerID ORDER BY O.OrderDate DESC )))
ORDER BY Orders.CustomerID, Orders.OrderDate DESC;

Regards,

Duane

Thanks Bill. Scores in Maths must be in regardless of the marks obtained. The others are the highest marks in five subjects among the remaining subjects.

Hi all,

the data below is hypothetical results of a student for simplicity in a situation where there are thousands of students who study varying number of subjects, with Maths being compulsory.

Would you know of a function that will help calculate the total marks in six best subjects ?

Thanks.

Ade
