Add a summary row with totals

Question

I know this sounds crazy and probably should not be done this way but I need something like this - I have a records from SELECT [Type], [Total Sales] From Before

Answer 1

You could use the ROLLUP operator

SELECT  CASE 
            WHEN (GROUPING([Type]) = 1) THEN 'Total'
            ELSE [Type] END AS [TYPE]
        ,SUM([Total Sales]) as Total_Sales
From    Before
GROUP BY
        [Type] WITH ROLLUP
