ORACLE SQL：合並 2 行 2 個單獨的選擇查詢

Question

你好，我對 SQL 很陌生，我有一個問題。 我有 3 表工作、收入和成本。 job.unid = cost.job_unid 和 Revenue.job_unid

我想找到每項工作的總收入和成本，然后在一行中找到每項工作的利潤：

標題看起來像這樣：工作編號、總收入、總成本、損益 (Rev-Cost)

我試圖做一個單一的查詢，但在互聯網上搜索解決方案后，我似乎應該單獨查詢收入和成本，然后使用聯合所有進行組合。

現在我這樣做：

  select m,
rlc,
rvatlc,
rtotlc,
clc,
cvatlc,
ctotlc
from(

(select decode(j.consolno,null,j.shpno,j.consolno) m,

sum(nvl(r.amtlc,0)) rlc,
sum(nvl(r.vatamtlc,0)) rvatlc,
sum(nvl(r.amtlc,0))+sum(nvl(r.vatamtlc,0)) rtotlc,
0 clc,
0 cvatlc,
0 ctotlc


from 
job j
full join revenue r on j.unid=r.job_unid
where j.voidby is  null and decode(j.consolno,null,j.shpno,j.consolno)='SHSEM00131'
group by decode(j.consolno,null,j.shpno,j.consolno)
)







union all




(select decode(j.consolno,null,j.shpno,j.consolno) m,


0 rlc,
0 rvatlc,
0 rtotlc,
sum(nvl(c.amtlc,0)) clc,
sum(nvl(c.vatamtlc,0)) cvatlc,
sum(nvl(c.amtlc,0))+sum(nvl(c.vatamtlc,0)) ctotlc


from 
job j, cost c 
where j.voidby is  null and j.unid=c.job_unid and decode(j.consolno,null,j.shpno,j.consolno)='SHSEM00131'
group by decode(j.consolno,null,j.shpno,j.consolno)
))

結果是：我不確定你是否能看到，但它是 2 行：1 是收入，1 是成本。
我想結合這兩行

Answer 1

嘗試這個。

   select m,
    sum(rlc),
    sum(rvatlc),
    sum(rtotlc),
    sum(clc),
    sum(cvatlc),
    sum(ctotlc)
    from(

    (select decode(j.consolno,null,j.shpno,j.consolno) m,

    sum(nvl(r.amtlc,0)) rlc,
    sum(nvl(r.vatamtlc,0)) rvatlc,
    sum(nvl(r.amtlc,0))+sum(nvl(r.vatamtlc,0)) rtotlc,
    0 clc,
    0 cvatlc,
    0 ctotlc


from 
job j
full join revenue r on j.unid=r.job_unid
where j.voidby is  null and decode(j.consolno,null,j.shpno,j.consolno)='SHSEM00131'
group by decode(j.consolno,null,j.shpno,j.consolno)
)

union all

(select decode(j.consolno,null,j.shpno,j.consolno) m,


0 rlc,
0 rvatlc,
0 rtotlc,
sum(nvl(c.amtlc,0)) clc,
sum(nvl(c.vatamtlc,0)) cvatlc,
sum(nvl(c.amtlc,0))+sum(nvl(c.vatamtlc,0)) ctotlc


from 
job j, cost c 
where j.voidby is  null and j.unid=c.job_unid and decode(j.consolno,null,j.shpno,j.consolno)='SHSEM00131'
group by decode(j.consolno,null,j.shpno,j.consolno)
)) group by m;
