oracle sql-如何按维度列获取全年（12个月）的总和

Question

enter code here ，我有一种情况需要比较2个表，第一个表是Z_F_DDEPL_ALLRPTG，第二个表是F_DDEPL_ALLRPTG，这两个表的耻辱列名称和列数相同。 有几列中有金额（从3月到2月是一年），所以我需要对这些金额列求和，并按剩余的维列分组，比较两个表，看看是否有金额差异。 这是我创建的sql，但是由于某种原因它没有给我我需要的输出，请帮助

select distinct 
YEAR_CD,
SCENARIO_CD,
MANAGEMENT_CD,
PRODUCT_CD,
OPCO_CD,
ACCOUNT_CD,
sum(BEGBALANCE_QTY) as BEGBALANCE_QTY ,
sum(MAR_QTY) as MAR_QTY,
sum(APR_QTY) as APR_QTY,
sum(MAY_QTY) as MAY_QTY,
sum(JUN_QTY) as JUN_QTY,
sum(JUL_QTY) as JUL_QTY,
sum(AUG_QTY) as AUG_QTY,
sum(SEP_QTY) as SEP_QTY,
sum(OCT_QTY) as OCT_QTY,
sum(NOV_QTY) as NOV_QTY,
sum(DEC_QTY) as DEC_QTY,
sum(JAN_QTY) as JAN_QTY,
sum(FEB_QTY) as FEB_QTY
from LND_FPAR.Z_F_DDEPL_ALLRPTG a 
 join LND_FPAR.F_DDEPL_ALLRPTG b
  on a.YEAR_CD=b.YEAR_CD
and a.SCENARIO_CD= b.SCENARIO_CD
and a.MANAGEMENT_CD=b.MANAGEMENT_CD
and a.PRODUCT_CD=b.PRODUCT_CD
 and a.OPCO_CD=b.OPCO_CD
 and a.ACCOUNT_CD=b.ACCOUNT_CD
--where opco_cd='OCO101'
 group by  
YEAR_CD,
SCENARIO_CD,
MANAGEMENT_CD,
PRODUCT_CD,
OPCO_CD,
ACCOUNT_CD
order by year_cd;

您可以使用union all和条件聚合来进行并排比较：

select YEAR_CD, SCENARIO_CD, MANAGEMENT_CD, PRODUCT_CD, OPCO_CD, ACCOUNT_CD,
       sum(case when which = 'a' then MAR_QTY end) as MAR_QTY_a,
       sum(case when which = 'b' then MAR_QTY end) as MAR_QTY_b,
       . . .
from ((select 'a' as which, YEAR_CD, SCENARIO_CD, MANAGEMENT_CD, PRODUCT_CD, OPCO_CD, ACCOUNT_CD,
              MAR_QTY, . . .
       from LND_FPAR.Z_F_DDEPL_ALLRPTG
      ) union all
      (select 'b' as which, YEAR_CD, SCENARIO_CD, MANAGEMENT_CD, PRODUCT_CD, OPCO_CD, ACCOUNT_CD,
              MAR_QTY, . . .
       from LND_FPAR.F_DDEPL_ALLRPTG
      )
     ) ab
group by YEAR_CD, SCENARIO_CD, MANAGEMENT_CD, PRODUCT_CD, OPCO_CD, ACCOUNT_CD;

（填写. . .你要比较的列。）

我不知道你想怎么做比较。
