MySql - order by monthname

问题

I am trying to order mysql query by month name like:

January --  5
February -- 2
March    -- 5
and so on

Here is my query, but its not ordering:

SELECT leave_balance.balance, MonthName(leave_balance.date_added) AS month 
FROM leave_balance WHERE leave_balance.staff_id_staff = $iid 
GROUP BY month,  leave_balance.leave_type_id_leave_type 
HAVING leave_balance.leave_type_id_leave_type = $leaveBalTypID 
ORDER BY month

Kindly tell me where I am doing wrong

回答1:

you can specify like

ORDER BY FIELD(MONTH,'January','February','March',...)


SELECT leave_balance.balance, MonthName(leave_balance.date_added) AS month 
FROM leave_balance WHERE leave_balance.staff_id_staff = $iid 
GROUP BY month,  leave_balance.leave_type_id_leave_type 
HAVING leave_balance.leave_type_id_leave_type = $leaveBalTypID 
ORDER BY FIELD(MONTH,'January','February','March',...,'December');

回答2:

try using the built in month function to get the month's number and order by that. For example:

order by month(leave_balance.date_added)

回答3:

Just add at the end:

ORDER BY str_to_date(MONTH,'%M')

回答4:

simply order by leave_balance.date_added field. By default it will sort by month.
