Question

计算甲骨文第一季度与第二季度的收入增长-> 我有一个销售表，其销售额为dt_invoice_date列。我如何在Oracle中做到这一点。我使用的年度收入增长代码是-

select yr1, yr2, sales1,sales2, (sales1-sales2)/sales2*100 as growth

from 
(select extract(year from dt_invoice_date)  yr1, sum(sale_value) as sales1 from base_sales_data_tbl  
group by  extract(year from dt_invoice_date) )S1

left outer join
 (select  extract(year from dt_invoice_date)  yr2, sum(sale_value) as sales2 from base_sales_data_tbl 
 group by extract(year from dt_invoice_date)
 ) S2
 ON yr1-1= yr2 ;

以类似的方式如何计算Oracle中的Qtr1 vs Qtr2收入增长。感谢您的提前帮助。

Answer 1

一种方法是按年份和季度计算季度和组：

select qtr1, yr1, qtr2, yr2, sales1,sales2, (sales1-sales2)/sales2*100 as growth

from 
(select extract(year from dt_invoice_date)  yr1, TRUNC(EXTRACT(MONTH FROM dt_invoice_date) / 3) qtr1, sum(sale_value) as sales1 from base_sales_data_tbl  
group by  extract(year from dt_invoice_date), TRUNC(EXTRACT(MONTH FROM dt_invoice_date) / 3)
)S1

left outer join
 (select  extract(year from dt_invoice_date)  yr2, TRUNC(EXTRACT(MONTH FROM dt_invoice_date) / 3) qtr2, sum(sale_value) as sales2 from base_sales_data_tbl 
 group by extract(year from dt_invoice_date), TRUNC(EXTRACT(MONTH FROM dt_invoice_date) / 3)
 ) S2
 ON (yr1 = yr2 
AND qtr1-1 = qtr2)
OR (yr1-1 = yr2
AND qtr1 = 1
AND qtr2 = 4);

Answer 2

您还可以使用此：

    with s1 as (select sum(s.sale_value) sales, to_char(dt_invoice_date,'yyyyq') yrq, lag(sum(s.sale_value),1) over (order by to_char(dt_invoice_date,'yyyyq')) sales_pq
    from base_sales_data_tbl s
    -- added to restrict dates to 1st and 2nd quarter
    where to_char (dt_invoice_date,'q') < 3
    group by to_char(dt_invoice_date,'yyyyq'))
    select yrq, lag(yrq,1) over (order by yrq) prev_q, sales, sales_pq, round((sales-sales_pq)*100/sales_pq,2) growth
    from s1
    order by yrq;
