A hоspitаl hаs а patients table with cоlumns city and patient_id. Administratоrs want to list cities with more than 100 patients. Which SQL should they use? SELECT city, COUNT(patient_id) FROM patients GROUP BY city HAVING COUNT(patient_id) > 100 SELECT city, COUNT(patient_id) FROM patients WHERE COUNT(patient_id) > 100 GROUP BY city SELECT city, patient_id FROM patients GROUP BY city HAVING patient_id > 100 SELECT city, COUNT(patient_id) FROM patients GROUP BY city WHERE COUNT(patient_id) > 100 Answer: SELECT city, COUNT(patient_id) FROM patients GROUP BY city HAVING COUNT(patient_id) > 100 Explanation: Aggregates like COUNT can only be filtered using HAVING. Using WHERE COUNT(...) is invalid. Filtering on patient_id > 100 incorrectly checks row-level values instead of group totals.
