ORACLE SQL：合并 2 行 2 个单独的 select 查询

Question

你好，我是 SQL 的新手，我有一个问题。我有 3 表工作、收入和成本。 job.unid = cost.job_unid 和 revenue.job_unid

我想找出每项工作的总收入和成本，然后在一行中找到每项工作的利润：

headers 看起来像这样： 作业编号、总收入、总成本、损益表 (Rev-Cost)

我尝试进行单个查询，但在互联网上搜索解决方案后，我似乎应该分别查询 Revenue 和 Cost，然后使用 Union All 合并。

现在我正在这样做：

  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)
))

结果是：我不确定你是否能看到，但它是 2 行： 1 是收入，1 是成本。
我想合并这两行

试试这个。

   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;
