AdventureWorks Database: Using a derived table with multiple values
45. Write a SQL query to find the productid, name, and colour of the items 'Blade', 'Crown Race' and 'AWC Logo Cap' using a derived table with multiple values.
Sample table: Production.Product

Sample Solution:
-- Selecting specific columns from the Product table
SELECT ProductID, a.Name, Color
-- From the Production schema's Product table, aliasing it as 'a'
FROM Production.Product AS a
-- Joining with a derived table using the VALUES clause to create a table with specified values
-- The derived table consists of a single column 'Name' with values 'Blade', 'Crown Race', and 'AWC Logo Cap'
INNER JOIN (VALUES ('Blade'), ('Crown Race'), ('AWC Logo Cap')) AS b(Name)
-- Joining condition: matching product names between the Product table and the derived table
ON a.Name = b.Name;
Explanation:
- The SQL query retrieves data from the Product table within the Production schema.
- It selects three columns: ProductID, Name, and Color.
- The INNER JOIN clause is used to join the Product table with a derived table created using the VALUES clause.
- The VALUES clause generates a table with specified values ('Blade', 'Crown Race', and 'AWC Logo Cap') for the column Name.
- This derived table is aliased as 'b'.
- The join condition links rows from the Product table with rows from the derived table based on matching Name values.
- The result set will include rows from the Product table where the Name matches any of the specified values in the derived table.
- Only matching rows will be returned, and the output will contain the ProductID, Name, and Color columns.
Sample Output:
productid|name |color|
---------+------------+-----+
316|Blade | |
323|Crown Race | |
712|AWC Logo Cap|Multi|
