Here’s the table with sample data:
CREATE TABLE [dbo].[Issues](
[Id] [int] IDENTITY(1,1) NOT NULL,
[WorkItem] [nvarchar](50) NOT NULL,
[DateSubmitted] [date] NOT NULL,
[DateFixed] [date] NULL,
PRIMARY KEY CLUSTERED (
[Id] ASC
)
)
INSERT [dbo].[Issues](
[WorkItem],
[DateSubmitted],
[DateFixed]
)
VALUES
('Test', '20130310', '20130310'),
('Test1', '20130310', NULL),
('Test2', '20130311', '20130313'),
('Test3', '20130311', '20130311'),
('Test4', '20130311', '20130320'),
('Test5', '20130312', '20130314'),
('Test6', '20130314', '20130315'),
('Test7', '20130314', '20130315'),
('Test8', '20130316', '20130319'),
('Test9', '20130319', '20130330'),
('Test10', '20130320', NULL)
He asked me to go through the table, and for each day count how many issues were submitted and how many were fixed. When he manually counted the values, he got the following results:
Date | Submitted | Fixed |
3/10/2013 | 2 | 1 |
3/11/2013 | 3 | 1 |
3/12/2013 | 1 | 0 |
3/13/2013 | 0 | 1 |
3/14/2013 | 2 | 1 |
3/15/2013 | 0 | 2 |
3/16/2013 | 1 | 0 |
3/19/2013 | 1 | 1 |
3/20/2013 | 1 | 1 |
3/30/2013 | 0 | 1 |
Select [Date]
, ISNULL([Submitted],0) as [Submitted]
, ISNULL([Fixed],0) as [Fixed]
FROM
(Select DateFixed as [Date], COUNT(Id) as ct, 'Fixed' as md
from dbo.[Issues]
where DateFixed is not NULL
group by DateFixed
UNION ALL
Select DateSubmitted as [Date], COUNT(Id) as ct, 'Submitted' as md
from dbo.[Issues]
where DateSubmitted is not NULL
group by DateSubmitted) as SourceTable
PIVOT
(sum(ct)
for md in ([Submitted], [Fixed])) as pvt
order by [Date]
And there you go. Fun day with new PIVOT-y toys.
