Question

This gives me the top 5 category/year combinations by spending:

SELECT TOP 3 [Category],
             SUM([Spending]),
             Year
FROM Data
GROUP BY [Category], [Year]
;

I would like to look at the overall top 5 categories for every year.

eg If the top spending categories over the 3 year period are A,B,C (but not D) I would like to output this:

  Category   Total Spending   Year
  A          123              1  
  A          321              2
  A          987              3
  B          798              1
  B          465              2 
  B          153              3
  C          654              1
  C          486              2
  C          759              3

This is solved here, but only with two fields- SQL: Select Top 3 Records + Sum of Quantity

Answer 1

Try in this way:

SELECT [Category], SUM([Spending]) as TotalSpending, Year
FROM Data
WHERE Year IN (SELECT TOP 5 Year FROM Data ORDER BY Year DESC)
GROUP BY [Category], [Year]
ORDER BY SUM([Spending])  DESC, [Year] DESC
