Re: [MS_AccessPros] Re: BEST SIX SUBJECTS

 

Ade,

I'm confused by your previous remarks "i know you do not like the excel format of tabulation' which I assume is my normal soap box regarding normalizing table structures while your current email suggests the table seems normalized.

So you have a table named [pls see below] with only three fields: [STUDENT EXAM NO], SUBJECT, and MARKS? (sorry, it is Friday afternoon)

Notice how I have taken the time to wrap any field name with spaces in []s for clarity. 

Regards,

Duane

Thanks Duane,

i know you do not like the excel format of tabulation but its easy for me and so I am showing the data here. I have changed i field to make a tie. Really a tie does not make a difference in this case as it leaves the calculation unchanged at 489marks. If there is a tie at higher marks, this only displaces the lower marks that would have been included.

Ade

Exam No	Maths	English	Science	History	Chemistry	Biology	Agric	Physics	Music	Greek
1	70	85	81	90	64	91	72	50	68	72

Please note also that a student can offer anything from 6 to 12 subjects but the best six are counted.

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

S/NO	SUBJECT	MARKS
1	Maths	70
2	English	85
3	Science	81
4	History	90
5	Chemistry	64
6	Biology	91
7	Agric	72
8	Physics	50
9	Music	68
10	Greek	59
	Sum of Best Six Marks	489
