我们来看下计算公式：

1、同比环比计算规则

月度环比=（本月-上月）/上月*100%

月度同比=（当年本月-上年本月）/上年本月*100%

年度同比=（今年-去年）/去年*100%

上面是收入表：

我要统计年度同比：（今年-去年）/去年*100%

	select 
	 t1.dtYear,
	 t1.sumAmount,
	 t2.latSumAmount, 
	     CASE
    WHEN latSumAmount IS NULL
     OR latSumAmount = 0 THEN
     0 ELSE ( CONVERT ( ( ( sumAmount - latSumAmount ) / latSumAmount ) * 100, DECIMAL ( 10, 2 ) ) )
      END hb
	 
	  from 
  (SELECT
	   date_format(f.dt,'%Y') dtYear,
		 SUM(f.amount) as sumAmount
 FROM
	   finance f 
		 GROUP BY dtYear) t1
		 
		 left join 
		   (SELECT
	   date_format(f.dt,'%Y') dtYear,
		 SUM(f.amount) as latSumAmount
 FROM
	   finance f 
		 GROUP BY dtYear) t2 on t1.dtYear = t2.dtYear + 1
		 

月度环比：月度环比=（本月-上月）/上月*100%

	select

        t1.sumAmount,

月度同比=（当年本月-上年本月）/上年本月*100%
