Answer 1

SELECT Phone_number, COUNT(*) AS no_answer_count
FROM Calls
WHERE System_outcome = 'no_answer'
GROUP BY Phone_number
HAVING no_answer_count > 5

Answer 2

你需要使用group by和where where condition

的组合

select Phone_number 
from Calls
where System_outcome='No Answer'
group by Phone_number      
having count(Phone_number) > 5

Answer 3

您可以group by电话号码并过滤那些大于5的having次

select phone_number
from Calls
where System_outcome = 'No Answer'
group by phone_number
having count(*) > 5;

Answer 4

public (bool success, string message, LotInfo lotInfo) GetLotInfo(string SupplierCode)
{
    // collect info
    return (true, "message lot info retrieved successfully", new LotInfo()); // put actual values here
}
