を返すものです。この

select ace.date, ace.balance, aacs.date, aacs.balance, 
axl.date, axl.balance, la.date, la.balance, 
mrh.date, mrh.balance 
from 
(select * 
from [Entity1] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as ACE 
full join 
(select *

Answer 1

あなたは参加しない組合でこれを行うだろう。次のようなものがあります。

select date, balance 
from [Entity1] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as ACE 
union 
select date, balance 
from [Entity2] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as AACS 
on ACE.GLCredited = AACS.GLCredited 
union 
select date, balance 
from [Entity3] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as AXL 
on AXL.GLCredited = AACS.GLCredited 
union 
select date, balance 
from [Entity4] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as LA 
on LA.GLCredited = AXL.GLCredited 
union 
select date, balance 
from [Entity5] 
where MONTH (date) = 05 AND YEAR (date) = 2017) as MRH 
on MRH.GLCredited = LA.GLCredited 

Answer 2

すべてのサブクエリに簡単にIS NOT NULLを追加できます。したがって、あなたは、サブクエリから取得リターンはあなたがUNIONを使用することができNULL

.... 
    from 
    from [Entity1] 
    where MONTH (date) = 05 AND YEAR (date) = 2017 and *DATE is not null*) as ACE 
    join 
(select * 
    from [Entity2] 
    where MONTH (date) = 05 AND YEAR (date) = 2017 *and BALANCE is not null*) as AACS 
    on ACE.GLCredited = AACS.GLCredited 
    join 

Answer 3

は含まれません：COLUMN_NAMEがNULLでないTABLE_NAME FROM

Select * 
FROM 
(
select 'ACE' as ScheduleName, date, balance from [Entity1] 
union 
select 'AACS' as ScheduleName, date, balance from [Entity2] 
union 
select 'AXL' as ScheduleName, date, balance from [Entity3] 
union 
select 'LA' as ScheduleName, date, balance from [Entity4] 
union 
select 'MRH' as ScheduleName, date, balance from [Entity5] 
)u 
where MONTH (date) = 05 AND YEAR (date) = 2017
