Final answer:
To select products sold as a set from the SQL Product table, use the LIKE operator with the wildcard character %, as in '%set%', which searches for product names containing the word 'set'.
Step-by-step explanation:
To select all products sold as a set from the Product table in an SQL statement, you need to use the LIKE operator to search for a specific pattern in the ProductName field. You can use the percent sign (%) as a wildcard to indicate that any sequence of characters can precede or follow the specified pattern. The correct SQL statement to find all products with 'set' in their names would look as follows:
SELECT ProductName, Quantity FROM Product WHERE ProductName LIKE '%set%';
This statement will retrieve both the product name and quantity for each product where the ProductName includes the word 'set', regardless of the characters that come before or after it.
