PHP Mysql GET上個月和當月數據

Question

我想檢索上個月的數據和當月的數據

我的查詢正常工作

上個月的數據從當前日期算起1個月。 但是我希望我的數據不是從當前日期起算為日歷月。

喜歡

我當前的日期是2014-07-23

現在，我的計算通過計算從當前日期開始的月份返回數據。

但我想基於日歷jan，feb，march范圍。

我上個月的當前查詢

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() 

我本月的當前查詢

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

上個月

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

這個月

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