MySQL的 - 为了通过MONTHNAME

Question

我试图通过月份名称订购MySQL查询，如：

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

这里是我的查询，但它不是订购：

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 

请告诉我，我在哪里做错了

Answer 1

你可以指定一个像

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'); 

Answer 2

尝试使用内置的月份函数来获取月份的数量和顺序。例如：

order by month(leave_balance.date_added) 

Answer 3

只需按leave_balance.date_added字段排序。默认情况下，它将按月排序。

Answer 4

只是在结尾处加上：

ORDER BY str_to_date(MONTH,'%M')
