php - PHP Mysql GET上个月和当月数据

我想检索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算起1个月。但是我希望我的数据不是从当前日期起算为日历月。

喜欢

我当前的日期是2014-07-23

现在，我的计算通过计算从当前日期开始的月份返回数据。

但我想基于日历1月，2月，3月范围。

我当前查询的上个月

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()

我本月的当前查询

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)

最佳答案

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)

这个月

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