MySQL计算环比、同比（年、月、季度）

环比

所谓“环比”即连续2个单位周期（比如连续两月）内的量的变化比。如今年8月比今年7月。当然这里的单位不一定是月,可以是任何时间单位。

环比增长率=（本期数-上期数）/上期数×100%。

反映本期比上期增长了多少；环比发展速度，一般是指报告期水平与前一时期水平之比，表明现象逐期的发展速度。

同比

所谓“同比”即同期比较，可以是本年度与上年度，也可以是上年同一个月份或季度与本年同期。

同比增长率=（本期数-同期数）/|同期数|×100%。

案例

按年月统计不同年份的销售总值，并计算环比（销售总额同比上期）、同比（销售总额同比去年同期）

备注：需要统计的是每个月的销售金额，而销售金额=出库金额-运费，即

sale_money= out_stock_money-freight_money；

create_time字段为下单时间，这里可以理解为销售时间

计算环比

思路：表a统计出每个年月份的销售总额，表b统计出上一个月的销售总额（在表a的基础上加上一个月，可得到上个月的销售量，这里可能有点绕），然后再将两个表进行左联接（通过now_time进行关联）。

#当前月份的销售额

select 
date_format(a.create_time,'%Y-%m') as now_time,
sum( a.out_stock_money) AS  a_out_money,
sum( a.freight_money) AS a_fre_money,
CONVERT (sum( a.out_stock_money)-sum( a.freight_money),DECIMAL ( 10,2 )) as a_sale_money
from food_orders_info a
where a.state=1
and a.order_state=60
GROUP BY date_format(a.create_time,'%Y-%m')

#上个月的销售额

select 
date_format(DATE_ADD(b.create_time,INTERVAL 1 MONTH ), '%Y-%m')   as now_time,
sum( b.out_stock_money) AS bout_money,
sum( b.freight_money) AS bfe_money,
CONVERT (sum(b.out_stock_money)-sum( b.freight_money),DECIMAL ( 10,2 )) as bsale_money
from food_orders_info b
where b.state=1
and b.order_state=60
GROUP BY date_format(DATE_ADD(b.create_time,INTERVAL 1 MONTH ), '%Y-%m')

备注：

DATE_ADD(b.create_time,INTERVAL 1 MONTH )  #表示加一个月

#当前月和上月销售额进行关联

SELECT
  now_sale.now_time,
  now_sale.now_year,
CASE
    WHEN a_sale_money IS NULL 
    OR a_sale_money = 0 THEN
      0 ELSE a_sale_money 
    END this_sale_money,

CASE
    WHEN b_sale_money IS NULL 
    OR b_sale_money = 0 THEN

  ORDER BY
    date_format( a.create_time, '%Y-%m' ) ASC 
  ) now_sale
  LEFT JOIN (

  ) old_sale ON now_sale.now_time = old_sale.now_time
ORDER BY
  now_sale.now_year DESC,
  now_sale.now_time ASC

得到的关联表

由于数据库销售金额有为空的情况，所以的加上判断条件，让为空或被除数为空的值，返回0。

再查询去年同期的销售金额

SELECT
    date_format( DATE_ADD( c.create_time, INTERVAL 1 YEAR ), '%Y-%m' ) AS last_year_time,
    sum( c.out_stock_money ) AS bout_money,
    sum( c.freight_money ) AS bfe_money,
    CONVERT ( sum( c.out_stock_money ) - sum( c.freight_money ), DECIMAL ( 10, 2 ) ) AS last_year_money 
  FROM
    food_orders_info c 
  WHERE
    c.state = 1 
    AND c.order_state = 60 
  GROUP BY
  date_format( DATE_ADD( c.create_time, INTERVAL 1 YEAR ), '%Y-%m' )

DATE_ADD( c.create_time, INTERVAL 1 YEAR ) 表示加一年。

得到的表如下：

最后，整合当前年月销售、上个月销售、去年同期销售。

  now_sale.now_time,
  now_sale.now_year,

    WHEN a_sale_money IS NULL

查询得到

month_radio即环比，year_ratio即同比。

按季度统计销售总额、环比

查询季度主要使用 QUARTER ( 时间)函数

方法和按年月统计类似，就直接上sql语句了

#查询当前季度销售总额
SELECT
    date_format( a.create_time, '%Y' ) AS now_year,
    QUARTER ( a.create_time ) a_quarter,
    CONCAT( YEAR ( a.create_time ), QUARTER ( a.create_time ) ) now_quarter,
    sum( a.out_stock_money ) AS a_out_money,
    sum( a.freight_money ) AS a_fre_money,
    CONVERT ( sum( a.out_stock_money ) - sum( a.freight_money ), DECIMAL ( 10, 2 ) ) AS a_sale_money 
  FROM
    food_orders_info a 
  WHERE
    a.state = 1 
    AND a.order_state = 60 
  GROUP BY
    CONCAT( YEAR ( a.create_time ), QUARTER ( a.create_time )),date_format( a.create_time, '%Y' ),  QUARTER ( a.create_time )

QUARTER ( a.create_time ) 指查询当前时间在哪一个季度

查询上一季度销售总额

SELECT
    CONCAT( YEAR ( b.create_time ), QUARTER ( DATE_ADD( b.create_time, INTERVAL 1 QUARTER ) ) ) AS last_quarter,
    sum( b.out_stock_money ) AS b_out_money,
    sum( b.freight_money ) AS b_fre_money,
    CONVERT ( sum( b.out_stock_money ) - sum( b.freight_money ), DECIMAL ( 10, 2 ) ) AS b_sale_money 
  FROM
    food_orders_info b 
  WHERE
    b.state = 1 
    AND b.order_state = 60 
  GROUP BY
  CONCAT( YEAR ( b.create_time ), QUARTER ( DATE_ADD( b.create_time, INTERVAL 1 QUARTER ) ) )

查询去年同季度销售额

SELECT
    CONCAT(YEAR( DATE_ADD( c.create_time, INTERVAL 1 year )),QUARTER(c.create_time)) as last_year_quarter,
    sum( c.out_stock_money ) AS c_out_money,
    sum( c.freight_money ) AS c_fre_money,
    CONVERT ( sum( c.out_stock_money ) - sum( c.freight_money ), DECIMAL ( 10, 2 ) ) AS c_sale_money 
  FROM
    food_orders_info c 
  WHERE
    c.state = 1 
    AND c.order_state = 60 
  GROUP BY
  CONCAT(YEAR( DATE_ADD( c.create_time, INTERVAL 1 year )),QUARTER(c.create_time))

查询本季度、上一季度的销售额，并统计环比
