SQL计数和合并

我正在设置一个查询来更改表单的数据，计算数据并格式化它。现在我得到了一个包含垂直数据的表格。数据如下图所示。

我想做的是根据数字创建Group by，然后计算特定TypePak的次数，并将其向右拆分。如右图所示

我试过做Pivot，它在一定程度上帮助了我，但这不是一个好方法。然后我尝试了XML路径

支点

XML路径

  select distinct Number, abc = STUFF(( 
    select ',' + TypePak 
    from des_ombouw t1
    where t1.Number = t2.Number
    FOR XML PATH ('')),1,1,'')
from des_ombouw t2

在图像中是我想要的。还有更多的列需要添加，比如一些包的重量。

还有一个问题是，会有更多的专栏，所以这还不是全部

使用

row\u number（）

的两个聚合步骤可以实现您想要的功能：

select d.number,
       max(case when seqnum = 1 then cnt end) as cnt_1,
       max(case when seqnum = 1 then typepak end) as typepak_1,
       max(case when seqnum = 2 then cnt end) as cnt_2,
       max(case when seqnum = 2 then typepak end) as typepak_2,
       max(case when seqnum = 3 then cnt end) as cnt_3,
       max(case when seqnum = 3 then typepak end) as typepak_3,
       max(case when seqnum = 4 then cnt end) as cnt_4,
       max(case when seqnum = 4 then typepak end) as typepak_4
from (select d.number, d.typepak, count(*) as cnt,
             row_number() over (partition by d.number order by count(*) desc) as seqnum
      from dbo.des_ombouw d
     ) d
group by d.number

这个形象被打破了。但是，与其尝试重新加载，不如不要。如果您正在提供数据，则最好将其作为表格格式的

文本

或DDL和DML语句来接收。@Larnu我已将图像添加到文本中。“但是，不要尝试重新加载它，而要尝试重新加载它。”

select d.number,
       max(case when seqnum = 1 then cnt end) as cnt_1,
       max(case when seqnum = 1 then typepak end) as typepak_1,
       max(case when seqnum = 2 then cnt end) as cnt_2,
       max(case when seqnum = 2 then typepak end) as typepak_2,
       max(case when seqnum = 3 then cnt end) as cnt_3,
       max(case when seqnum = 3 then typepak end) as typepak_3,
       max(case when seqnum = 4 then cnt end) as cnt_4,
       max(case when seqnum = 4 then typepak end) as typepak_4
from (select d.number, d.typepak, count(*) as cnt,
             row_number() over (partition by d.number order by count(*) desc) as seqnum
      from dbo.des_ombouw d
     ) d
group by d.number
