I have a requirement to show formatted data in a report. I am using three tables where one adds new users, second one for their payments and the last one for if any user resigns. So here are the sample tables and default data:
我需要在报告中显示格式化数据。我使用三个表,其中一个添加新用户,第二个用于付款,最后一个用于任何用户辞职。以下是示例表和默认数据:
CREATE TABLE [dbo].[Entry]
(
[EmpId] [int] IDENTITY(1,1) NOT NULL,
[EmpName] [nvarchar](40) NULL,
[Address] [nvarchar](100) NULL,
[Email] [nvarchar](20) NULL,
[EntryDate] [datetime] NULL
)
INSERT [dbo].[Entry] ([EmpId], [EmpName], [Address], [Email], [EntryDate])
VALUES (1, N'John', N'On Earth', N'john@abc.com', CAST(0x0000A58000000000 AS DateTime)),
(2, N'Jack', N'On Earth', N'jack@abc.com', CAST(0x0000A5A800000000 AS DateTime)),
(3, N'Jessi', N'On Earth', N'jessi@abc.com', CAST(0x0000A5CF00000000 AS DateTime)),
(4, N'Jackson', N'On Earth', N'jackson@abc.com', CAST(0x0000A5E400000000 AS DateTime))
CREATE TABLE [dbo].[Payment]
(
[Id] [int] IDENTITY(1,1) NOT NULL,
[EmpId] [int] NULL,
[Payment] [float] NULL,
[PayDate] [datetime] NULL
)
INSERT [dbo].[Payment] ([Id], [EmpId], [Payment], [PayDate])
VALUES (1, 1, 2000, CAST(0x0000A61800000000 AS DateTime)), (2, 1, 2000, CAST(0x0000A63600000000 AS DateTime)),
(3, 1, 2000, CAST(0x0000A65500000000 AS DateTime)), (4, 1, 2000, CAST(0x0000A67400000000 AS DateTime)),
(5, 2, 4000, CAST(0x0000A5DB00000000 AS DateTime)), (6, 2, 4000, CAST(0x0000A5F900000000 AS DateTime)),
(7, 2, 4000, CAST(0x0000A61800000000 AS DateTime)), (8, 2, 4000, CAST(0x0000A63600000000 AS DateTime)),
(9, 2, 4000, CAST(0x0000A65500000000 AS DateTime)), (10, 2, 4000, CAST(0x0000A67400000000 AS DateTime)),
(11, 2, 4000, CAST(0x0000A69200000000 AS DateTime)), (12, 3, 6000, CAST(0x0000A65500000000 AS DateTime)),
(13, 3, 6000, CAST(0x0000A67400000000 AS DateTime)), (14, 4, 8000, CAST(0x0000A7FF00000000 AS DateTime)),
(15, 4, 8000, CAST(0x0000A98B00000000 AS DateTime))
CREATE TABLE [dbo].[Resign]
(
[Id] [int] IDENTITY(1,1) NOT NULL,
[EmpId] [int] NULL,
[ResignDate] [datetime] NULL,
[Reason] [nchar](10) NULL
)
INSERT [dbo].[Resign] ([Id], [EmpId], [ResignDate], [Reason])
VALUES (1, 1, CAST(0x0000A69B00000000 AS DateTime), N'Resigned '),
(2, 2, CAST(0x0000A6C400000000 AS DateTime), N'Resigned')
The required output is as follows that'll be year-wise:
所需的输出如下:这将是逐年的:
Year 2015
Month - Jan - Feb - Mar - Apr - May - Jun - Jul - Aug - Sep - Oct - Nov - Dec
Opening - 10 - 10 - 10 - 12 - 12 - 12 - 12 - 12 - 12 - 12 - 8 - 8 //Total no. of employee
Add - 0 - 0 - 2 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 //Newly added
Left - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 0 - 4 - 0 - 0 //Resigned
Closing - 10 - 10 - 12 - 12 - 12 - 12 - 12 - 12 - 12 - 8 - 8 - 8 //Closing Total
Year 2016
Month - Jan - Feb - Mar - Apr - May - Jun - Jul - Aug - Sep - Oct - Nov - Dec
Opening - 8 ----Goes on in the similar way
Add -----
Left ----
Closing ----
So this is clear how the data should be shown in the report. Though I am aware of the grouping year-wise in the report and have tried similar to show the data month-wise as follows:
因此,很清楚如何在报告中显示数据。虽然我知道报告中的年度分组,并尝试过类似的数据,按月显示数据如下:
SELECT
DATEPART(YYYY, Q.PayDate) [YEAR],
COUNT(m.EmpId) Total,
SUM(CASE WHEN DATENAME(MONTH, m.EntryDate) = 'January' THEN 1 ELSE 0 END) [JAN],
SUM(CASE WHEN DATENAME(MONTH, m.EntryDate) = 'February' THEN 1 ELSE 0 END) [FEB]
FROM
Entry m
INNER JOIN
Payment q ON Q.EmpId = M.EmpId
LEFT JOIN
Resign OUT ON OUT.EmpId = m.EmpId
WHERE
m.EmpId NOT IN (SELECT DISTINCT p.EmpId FROM Resign p)
AND m.EmpId IN (SELECT DISTINCT k.EmpId FROM Payment k)
GROUP BY
DATEPART(YYYY, Q.PayDate), DATEPART(MM, m.EntryDate);
The above query returns something as follows:
上面的查询返回如下内容:
YEAR Total JAN FEB
--------------------
2016 2 0 0
2017 1 0 0
2018 1 0 0
But I am not sure how can I show the newly added as well resigned users with the opening in the same query row-wise as the sample given?
但我不确定如何在给出的样本中以相同的查询行显示新添加的以及已重新排列的用户?
N.B: I am open to any query languages. So expecting your ideas to implement it in an appropriate way.
N.B:我对任何查询语言都是开放的。因此,期待您的想法以适当的方式实施。

You should definitely shift your effort over to a reporting tool such as SSRS if you plan to run many of these. It will simplify things many times over. That being said, here is one way that would produce the results you mentioned above.
