我有两个表,一个是WeekNr和OrderNum,一个是OrderNum,Article和ammount
表一
WeekNr OrderNum
35 10001
35 10003
35 10008
36 10006
36 10005
37 10004
38 10007
39 10002
表2
OrderNum Article Ammount
10001 A 5
10001 B 2
10002 A 2
10003 A 1
10003 B 2
10004 A 10
10005 B 1
10007 B 3
如何获得像
这样的结果Article Total WeekNr35-36, Total WeekNr 37-38, Total WeekNr 39-40
A 8 10 2
B 5 3 0
答案 0 :(得分:0)
您可以使用以下查询
select b.article,
sum(case when a.weeknr in (35,36) then b.amount end ) as "Total WeekNr35-36",
sum(case when a.weeknr in (37,38) then b.amount end ) as "Total WeekNr37-38",
sum(case when a.weeknr in (39,40) then b.amount end ) as "Total WeekNr39-40"
from table_one a inner join table_two b
on a.ordernum=b.ordernum
group by b.article

定义句点表,以便更轻松地对数据进行分组,以便在以后需要延长句点或者需要制作自定义标题时更加简单。我的建议是:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<div class="row">
<div id="left" class="col-sm-3">
<div class="row">
<h1 class="col-sm-12">TEST TITLE</h1>
</div>
</div>
<div id="right" class="col-sm-9">
<nav class="row">
<ul>
<li class="header_sm_text col-sm-12">TEST LINK</li>
</ul>
</nav>
</div>
</div>
</div>
然后创建一个分组数据集,使用pivot函数
进行转换Period, PeriodText, Week
1, 'Weeks 24 and 25', 24
1, 'Weeks 24 and 25', 25
此外,我建议合并你的两个表,并将周数放入订单表。 此外,您可以插入一个运行一周功能的订单日期。
