Sample Solution:

-- Selecting color, total list price, and total standard cost for products with names starting with 'Mountain'
SELECT Color, SUM(ListPrice), SUM(StandardCost)  
-- From the Product table in the Production schema
FROM Production.Product  
-- Filtering records where Color is not NULL, ListPrice is not zero, and the product name starts with 'Mountain'
WHERE Color IS NOT NULL   
    AND ListPrice != 0.00   
    AND Name LIKE 'Mountain%'  
-- Grouping the results by Color
GROUP BY Color  
-- Ordering the results by Color
ORDER BY Color;

Explanation:

• This SQL query retrieves the total list price and total standard cost for products with names starting with 'Mountain', grouped by color.
• The SELECT clause specifies the columns to be retrieved: Color, the sum of ListPrice, and the sum of StandardCost.
• The FROM clause indicates the source table, which is Product in the Production schema.
• The WHERE clause filters the records based on specific conditions:
• Color IS NOT NULL: Ensures that only records with non-null color values are included.
• ListPrice != 0.00: Filters out products with a list price of zero.
• Name LIKE 'Mountain%': Selects only products whose names start with 'Mountain'.
• The GROUP BY clause groups the results by Color, so the aggregate functions (SUM) are applied to each distinct color category.
• The ORDER BY clause arranges the output by Color in ascending order.

Sample Output:

color |sum     |sum       |
------+--------+----------+
Black |27404.84|15214.9616|
Silver|26462.84|14665.6792|
White |    19.0|    6.7926|
