Sample Solution:
-- Selecting Color, the total ListPrice, and the total StandardCost
SELECT Color, SUM(ListPrice) AS TotalList,
SUM(StandardCost) AS TotalCost
-- From the Product table in the Production schema
FROM production.product
-- Grouping the results by Color
GROUP BY Color
-- Ordering the results by Color
ORDER BY Color;
Explanation:
- This SQL query retrieves the total ListPrice and total StandardCost for each distinct Color of products.
- The SELECT clause specifies the columns to be retrieved: Color, the sum of ListPrice as TotalList, and the sum of StandardCost as TotalCost.
- The FROM clause indicates the source table, which is Product in the Production schema.
- The GROUP BY clause groups the results by the Color column, allowing aggregation to be performed on each color group.
- The ORDER BY clause arranges the output in ascending order based on the Color column.
