Question

我有两张桌子HOUR包含3个部分的小时（A0001，B0001，C0001），不同的TYPE（A，B，C）和PART包含3个部分的EAU（A0001，B0001，C0001）来自KEYID-29395 ：

当使用sumproduct

选择KEYID = 29395时，我希望获得3种不同类型的总小时数

TYPEA_TOTAL_HOUR = 1*100 + 4*200 + 7*300 
TYPEB_TOTAL_HOUR = 2*100 + 5*200 + 8*300
TYPEC_TOTAL_HOUR = 3*100 + 6*200 + 9*300

我如何使用SQL Server 2012实现这一目标？

Answer 2

像这样加入两个表和AGGREGATE：

select
    a.keyid,
    sum(a.typea * b.eau) typea_total_hour,
    sum(a.typeb * b.eau) typeb_total_hour,
    sum(a.typec * b.eau) typec_total_hour
from hour a
join part b
on a.partid = b.partid
and a.keyid = b.keyid
group by a.keyid;

如何从两个表中查询（SumProduct）
