Everything checks about right in your query and you are just missing a HAVING COUNT(*)>=2 clause Try This

SELECT City,COUNT(EmployeeID) AS numofsalesrep FROM empolyees WHERE Title='sales representatives' GROUP BY City HAVING COUNT(*)>=2 ORDER BY COUNT(EmployeeID) DESC, City;

CodePudding user response：

SELECT City, COUNT(EmployeeID) AS numofsalesrep  
FROM employees 
WHERE Title = 'sales representative' AND numofsalesrep >= 2 
GROUP BY City
ORDER BY numofsalesrep DESC, City;
