NEW QUESTION # 181
An analyst has written the following code:
SELECT *
FROM Cust_table
WHERE age > 60 AND City = "New York"
Which of the following criteria is the analyst retrieving?

A. All customers older than age 60 in New York state
B. All customers older than age 60 in New York City
C. All customers younger than age 60 in New York City
D. All customers aged 60 and older in New York state

Answer: B

Explanation:
The SQL query provided is selecting all records from the Cust_table where the age column has values greater than 60 and the City column matches "New York". The > operator selects values that are strictly greater than the comparison value, so it does not include customers aged exactly 60. The term "New York" in the context of a city database typically refers to New York City, not the state of New York. Therefore, the correct answer is that the analyst is retrieving data for all customers older than age 60 in New York City.
References:
* The use of the > operator in SQL is to select values greater than the specified value1.
* Understanding the WHERE clause in SQL and its use in filtering records based on specified conditions2.
* Clarification on the distinction between city and state names in database records3.
