PHP Mysql GET 上个月和当月数据

Question

我想检索m上个月的数据和当月的数据

我的查询正常工作

上个月的数据从当前日期计算 1 个月。但我希望我的数据按日历月计算，而不是从当前日期计算。

喜欢

我当前的日期是 2014-07-23

现在我的计算通过从当前日期计算月份来返回数据。

但我想根据日历一月、二月、三月范围进行获取。

我上个月当前的查询

SELECT (100*AVG((m.carbs)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_carbs,(100*AVG((m.fat)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_fat,(100*AVG((m.protein)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_protein
FROM `meal` AS m,`user_history` as u where u.meal_id=m.id and u.user_id=$user_id and date(FROM_UNIXTIME(u.create)) BETWEEN SUBDATE(CURDATE(), INTERVAL 1 MONTH) AND NOW() 

本月我当前的查询

SELECT (100*AVG((m.carbs)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_carbs,(100*AVG((m.fat)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_fat,(100*AVG((m.protein)/((m.carbs)+(m.fat)+(m.protein)))) AS Percantage_protein
FROM `meal` AS m,`user_history` as u where u.meal_id=m.id and u.user_id=$user_id and YEARWEEK(date(FROM_UNIXTIME(u.create))) = YEARWEEK(CURRENT_DATE)

Answer 1

上个月

year(date(FROM_UNIXTIME(u.create))) = year(CURDATE() - INTERVAL 1 MONTH)
and month(date(FROM_UNIXTIME(u.create))) = month(CURDATE() - INTERVAL 1 MONTH)

本月

year(date(FROM_UNIXTIME(u.create))) = year(CURDATE())
and month(date(FROM_UNIXTIME(u.create))) = month(CURDATE())
