Question

我具有一个季度按月平均产品销售量的汇总输出，如下所示：

汇总输出：

Product    Month    Sales
------------------------------
Product1    MAY    101.27
Product2    MAY    5.47
Product1    JUN    1481.19
Product2    JUN    84.95
ALL         QTR    836.44

我需要以下格式的最终输出：

            Product1  Product2   AverageSales
May         101.27    1481.19    (null)
Jun         5.47      84.95      (null)
Jul         0         0          (null)    
ALL         (null)    (null)     836.44

我尝试对月份应用透视，但是由于月份名称是基于所选季度的动态值，因此我尝试对产品进行透视：

select * from (rollup output) 
PIVOT MIN(Sales) FOR Product IN ('Product1' AS Product1_sales, 'Product2' AS Product2_sales, 'ALL' AS Average Sales');

我收到以下输出：

MONTH  Product1_sales    Product2_sales    Average Sales
MAY    5.47                 (null)              (null)
MAY     (null)              101.27              (null)  
JUN    84.95                (null)              (null)
JUN     (null)              1481.19             (null)
Qtr     (null)              (null)              836.44

但是，我需要上述最终格式的数据。我该如何实现？另外，如果没有该季度给定月份的数据，我想将其值显示为0（也以上述最终格式显示）。考虑到月份名称是动态的，我该如何实现？

编辑：我也可以使用产品进行透视，因为我不希望从动态透视中得到xml输出。

Answer 1

我不确定为什么需要动态调整，因为月数不太可能更改。为什么不只是：

select product
     , nvl(jan,0) as jan
     , nvl(feb,0) as feb
     , nvl(mar,0) as mar
     , nvl(apr,0) as apr
     , nvl(may,0) as may
     , nvl(jun,0) as jun
     , nvl(jul,0) as jul
     , nvl(aug,0) as aug
     , nvl(sep,0) as sep
     , nvl(oct,0) as oct
     , nvl(nov,0) as nov
     , nvl(dec,0) as dec
from   rollup_output
pivot  (min(sales) for (month) in
       ( 'JAN' as jan, 'FEB' as feb, 'MAR' as mar, 'APR' as apr, 'MAY' as may, 'JUN' as jun
       , 'JUL' as jul, 'AUG' as aug, 'SEP' as sep, 'OCT' as oct, 'NOV' as nov, 'DEC' as dec)
       );
