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.

Sample Output:

color       |totallist|totalcost |

Black       |67436.260|38636.5002|
