SQl 查询、子查询格式问题

Question

我需要有人帮助我进行一些格式设置。我试图使用子查询和 UNION ALL 等将其放入一行，但没有成功。这似乎很容易，但我只是用这个把头撞在墙上。 table 的布局与数据类似：

Date    pTypeCode   Location    Amt

1/1/2015    C   Store1  50.21

1/1/2015    C   Store1  125.62

1/1/2015    P   Store 1 250.1

1/1/2015    EB  Store 1 125.01

1/1/2015    C   Store 2 50.25

1/1/2015    C   Store 2 100.25

1/1/2015    EB  Store 2 125.25

1/3/2015    EB  Store 1 35.25

1/3/2015    C   Store 1 35.25

1/3/2015    C   Store 1 35.25

1/3/2015    P   Store 1 35.25

1/3/2015    C   Store 2 85.15

1/3/2015    C   Store 2 65.25

1/3/2015    P   Store 2 65.25

1/3/2015    EB  Store 2 65.25

我需要它来获取 pTypeCode 的计数作为每行的列数。我可以通过这样的简单查询轻松获取我想要的数据：

SELECT Date, LOCATION,
             pTypeCode,
             Count(pTypeCode),
             Sum(Amt) AS Prem
FROM [dbo].[CommisionEntry]
WHERE Date >=
    (SELECT DATEADD(DAY, 1, EOMONTH(GetDate(), -1)))
  AND Date <=
    (SELECT EOMONTH(GetDate()))
GROUP BY date, LOCATION,
               pTypeCode

但我需要行中的 count(pTypeCode) = P 和 C 和 EB 也像这样：

Date  Count(pTypeCode) C    Count(pTypeCode) P  Count(pTypeCode) EB    SUM(Amt)

1/1/2015  2  1  1  550.94

如有任何帮助，我们将不胜感激。

谢谢

Answer 1

如果您没有可用的数据透视表之类的东西（尽管您应该这样做，因为看起来您正在使用 T-SQL），您可以为每个值创建列，如下所示：

select
  date
  ,sum(case pTypeCode when 'C' then 1 else null end) count_c
  ,sum(case pTypeCode when 'P' then 1 else null end) count_p
  ,sum(case pTypeCode when 'EB' then 1 else null end) count_eb
  ,sum(amt) sum_amt
from
  CommisionEntry
where date >=
  dateadd(day, 1, eomonth(GetDate(), -1))
    and date <= eomonth(GetDate())
group by
  date

Answer 2

select  distinct a.date,
   a.Location,
   b.C,
   c.EB,
   d.p,
   e.amt

   from (select * from test1 group by date,location) as A
   left outer join
        (select date,count(*) as C, location from test1 where pTypeCode = "C" group by date,location) as b
   on a.date = b.date
   and a.location = b.location     
   left outer join
        (select date,count(*) as EB, location from test1 where pTypeCode = "EB" group by date,location) as c
   on a.date = c.date
   and a.location = c.location    
   left outer join
        (select date,count(*) as P, location from test1 where pTypeCode = "P" group by date,location) as d
   on a.date = d.date
   and a.location = d.location     
   left outer join
        (select date,location,sum(Amt) as Amt, location from test1 group by date, location) as e
   on a.date = e.date
   and a.location = e.location
   order by a.date,a.location;
