List the amount of the total sales of reseller sales by business type.
-- First find the business type to determine you have them all. Then create your query.
-- 3 Rows

I'm not sure how to translate 'First find the business type' to SQL code.

SELECT SUM(ROUND(S.[OrderQuantity] * S.UnitPrice, 2)) AS TotalSales
FROM dbo.DimReseller AS R
INNER JOIN dbo.FactResellerSales AS S
ON R.ResellerKey = S.ResellerKey

They want you to use a GROUP BY with business type.

I think they mean that you need to show the total sales for each business type. So you need to add the business type as a column in the select list. When you do that, it will also require that you add that column in the GROUP BY clause.

SELECT R.BusinessType, SUM(R.AnnualSales) AS TotalSales
FROM dbo.DimReseller AS R
GROUP BY R.BusinessType

I believe this is correct.
