【问题描述】：
我收到了 Firebird 1.5 的查询：
select * from (
select
ddddd.name,
gggg.land,
dd.maskenkey,
ddd.name,
Sum(b.epreis*a.menge),
Sum((kx.epreis / lx.kurs) * a.menge),
sum(case when b.bverpa_id='1' then (a.menge*e.p_volume)/e.pcs_box else a.menge*e.P_PCS_20ST end) as jumlah
from brrcp a
left outer join baufpo b on a.baufpo_id_aufnrpos = b.id
left outer join brrc c on a.brrc_id_rgnr = c.id
left outer join bauf d on b.bauf_id_linkkey = d.id
left outer join bkunde dd on d.bkunde_id_kunr = dd.id
left outer join badr ddd on dd.badr_id_adrnr = ddd.id
left outer join bvert dddd on d.bvert_id = dddd.id
left outer join badr ddddd on dddd.badr_id = ddddd.id
left outer join bbesp kx on b.id = kx.baufpo_id_aufpos
left outer join bbes aa on kx.bbes_id_linkkey = aa.id
left outer join bsal yy on kx.bsal_id = yy.id
left outer join bwaer lx on kx.bwaer_id_waehrungk = lx.id
left outer join bplz zz on ddd.bplz_id_landplz = zz.id
left outer join bland gggg on zz.bland_id_landkennz = gggg.id
left outer join bsa e on a.bsa_id_artnr = e.id
where c.eta_shipment between '01/01/2015' and '6/30/2015'
and dd.maskenkey starting 'AS-' and d.cancel = 'N' and d.confirm = 'N' and aa.status_po <> 'C'
and d.auftrag = 'J' and a.rg_buchungsart Is Null
group by ddddd.name,gggg.land,dd.maskenkey,ddd.name) abc
如何修复它的结构，因为当我想执行这个查询时，我会得到错误？谢谢 ！！

【问题讨论】：
-
我强烈建议使用更有意义的别名
-
我继续我朋友的工作。不是我自己的
-
你为什么还要使用
SELECT * FROM (SELECT ... )在这种情况下这是一个不必要的间接级别。
