我使用sum聚合函数和子查询生成记录,但别名在内部查询中不起作用。 我的查询是
select UPP.item_total,
(select sum(INN.item_value_afs) total_item_value_afs from
(select distinct INN.reg_no,INN.tpt_cuo_nam,INN.item_total,INN.item_value_afs
from sigtasad.customs_import_data INN where INN.reg_no=UPP.reg_no and INN.tpt_cuo_nam=UPP.tpt_cuo_nam)) total_item_value,
sum(UPP.code_tax_amount), UPP.cmp_nam from SIGTASAD.CUSTOMS_IMPORT_DATA UPP where
UPP.reg_no='38699' and UPP.company_tin='9003247336' group by
UPP.reg_no,UPP.tpt_cuo_nam,UPP.cmp_nam,UPP.item_total ;
此查询生成此错误: ORA-00904:" UPP"。" TPT_CUO_NAM":无效标识符
我想要这样的结果!!!

您的查询有很多错误和不良习惯。例如:
select
。sum()
。sum()
根据您展示的图片,您可能想要这样的内容:
select upp.item_total,
sum(item_value_afs) as total_item_value,
sum(upp.code_tax_amount),
upp.cmp_nam
from SIGTASAD.CUSTOMS_IMPORT_DATA upp
where upp.reg_no = '38699' and upp.company_tin = '9003247336'
group by upp.cmp_nam, upp.item_total ;
或者也许:
select upp.item_total,
sum(sum(item_value_afs)) over (partition by upp.cmp_nam, upp.item_total) as total_item_value,
sum(upp.code_tax_amount),
upp.cmp_nam
from SIGTASAD.CUSTOMS_IMPORT_DATA upp
where upp.reg_no = '38699' and upp.company_tin = '9003247336'
group by upp.cmp_nam, upp.item_total ;

你最里面的子查询
(select distinct nn.reg_no,inn.tpt_cuo_nam, inn.item_total, inn.item_value_afs
from sigtasad.customs_import_data inn
where inn.reg_no = upp.reg_no and inn.tpt_cuo_nam = upp.tpt_cuo_nam
)
引用未加入的表(upp
)。它也没有别名,但问题会在以后出现。请注意,似乎还有nn.reg_no
类型而不是inn.reg_no
这里没有显示表格的结构,但修复问题意味着:
(select distinct inn.reg_no,inn.tpt_cuo_nam, inn.item_total, inn.item_value_afs
from sigtasad.customs_import_data inn, SIGTASAD.CUSTOMS_IMPORT_DATA upp
where inn.reg_no = upp.reg_no and inn.tpt_cuo_nam = upp.tpt_cuo_nam
)
