Which SQL statement would show the type of pet most preferred by retirees?
A. SELECT Species FROM TblPets WHERE OwnerAge >64
B. SELECT OwnerAge FROM Tblowner WHERE OwnerAge >64
C. INSERT INTO TblPets (Owner, Species) VALUES (Retired', 'Pet')
D. SELECT Species FROM TblOwners WHERE Pet 'Yes'
Answer (2)
Option a selects the species of pets where the owner's age is greater than 64.
Option b selects the owner's age where the owner's age is greater than 64.
Option c inserts a new record with a retired owner and a generic pet species.
Option d has a syntax error and doesn't logically connect owners to pets or filter by age. The correct answer is \boxed{a}.
Explanation
Understanding the Problem The question asks us to identify the SQL statement that retrieves the type of pet most preferred by retirees. We need to analyze each option and determine which one correctly filters the data to show pet preferences among owners who are retirees.
Analyzing Each Option Let's examine each option:
Option a: SELECT Species FROM TblPets WHERE OwnerAge > 64 This statement selects the species from the TblPets table where the owner's age is greater than 64. This is likely to represent retirees, so this option seems promising.
Option b: SELECT OwnerAge FROM Tblowner WHERE OwnerAge > 64 This statement selects the owner's age from the Tblowner table where the owner's age is greater than 64. This only gives us the ages of the owners, not the pet types, so it's not helpful.
Option c: INSERT INTO TblPets (Owner, Species) VALUES ('Retired', 'Pet') This statement inserts a new record into the TblPets table, indicating a retired owner and a generic 'Pet' species. This doesn't show any preference, and it's an insertion, not a selection.
Option d: SELECT Species FROM TblOwners WHERE Pet 'Yes' This statement attempts to select the species from the TblOwners table where the 'Pet' column is 'Yes'. This statement has a syntax error ( WHERE Pet 'Yes' ) and doesn't logically connect owners to pets or filter by age.
Determining the Correct Statement Based on the analysis, option a is the most suitable because it selects the species of pets from a table (presumably containing pet information) and filters the results to include only owners older than 64, which is a reasonable proxy for retirees.
Conclusion Therefore, the correct SQL statement is option a.
Examples
Understanding SQL queries is essential in data analysis. For instance, a marketing company might use a similar query to identify the most popular product among a specific demographic, such as senior citizens. By analyzing purchasing patterns, they can tailor their advertising campaigns to better reach their target audience and increase sales. This type of data-driven decision-making is crucial for businesses to stay competitive in today's market.
The correct SQL statement to show the type of pet most preferred by retirees is option A: SELECT Species FROM TblPets WHERE OwnerAge > 64 , as it effectively retrieves pet species for owners aged over 64, likely representing retirees. Other options either fail to connect pet data with age or are irrelevant. Option A directly addresses the preference for pets among retirees.
