How to find out sum of dynamic columns in SQL Pivot Query - sql-server

Question

I have a stored procedure which accepts date and month as parameters that results monthly attendance sheet. And I have to find out the monthly working hours of particular employees.
CREATE TABLE [dbo].[employee] (
[EmpID] [int] IDENTITY(100,1) NOT NULL,
[Name] [varchar](50) NULL,
[DOB] [date] NULL,
[DOJ] [date] NULL,
[Email] [varchar](50) NULL,
[Mob] [varchar](50) NULL,
[Address] [varchar](max) NULL,
CONSTRAINT [PK_tbl_employee] PRIMARY KEY CLUSTERED
(
[EmpID] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
CREATE TABLE [dbo].[Attendace] (
[EmpID] [int] NOT NULL,
[AttendaceDate] [date] NULL,
[WorkHours] [int] NULL,
[AtID] [int] IDENTITY(1,1) NOT NULL,
CONSTRAINT [PK_Attendace] PRIMARY KEY CLUSTERED
(
[AtID] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
GO
Stored Procedure
ALTER procedure [dbo].[sps_AttendanceShowModified] #mon int, #year int
As begin DECLARE #cols AS NVARCHAR(MAX)=''; DECLARE #query AS
NVARCHAR(MAX)='';
set #query = 'SELECT * from (
select e.Name, a.WorkHours, DAY(a.AttendaceDate) AS d1
from Attendace a, employee e
where e.EmpID = a.EmpID and
MONTH(a.AttendaceDate) = ' + CONVERT(VARCHAR(12), #mon)+ ' AND
YEAR(a.AttendaceDate) = ' + CONVERT(VARCHAR(12), #year)+ ' ) src pivot
(
max(WorkHours) for d1 in ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30])
) piv'
execute(#query) end

Answer 1

In your are case you can add a column in your select list like following.
sum(WorkHours) over(partition by name order by (select 1)) as Total
I have created a Demo, you can have a look.

Your final query should look like following.
ALTER procedure [dbo].[sps_AttendanceShowModified] #mon int, #year int
As begin DECLARE #cols AS NVARCHAR(MAX)=''; DECLARE #query AS
NVARCHAR(MAX)='';
set #query = 'SELECT name,Total,[1],[2],[3] from (
select e.Name, a.WorkHours, DAY(a.AttendaceDate) AS d1, sum(WorkHours) over(partition by e.name order by (select 1)) as Total
from Attendace a, employee e
where e.EmpID = a.EmpID and
MONTH(a.AttendaceDate) = ' + CONVERT(VARCHAR(12), #mon)+ ' AND
YEAR(a.AttendaceDate) = ' + CONVERT(VARCHAR(12), #year)+ ' ) src pivot
(
max(WorkHours) for d1 in ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30])
) piv'
execute(#query) end
Note: You need to include other columns in your select.
