here is my sql query of CTE

 

;With CTE As

(

select EmployeeDetails.EmpID,EmployeeDetails.EmpName,EmployeeDetails.OTEntitled from EmployeeDetails

)

,CTE4 As

(

Select MachineAttendance.EmpID,MachineAttendance.Datetime,MachineAttendance.INOUT from MachineAttendance

)

,cte1 AS

(

SELECT CTE4.EmpID, CAST(CTE4.Datetime as Date) AS [Date],

CASE WHEN CTE4.INOUT = 1 THEN CTE4.DateTime END AS INOUT_INTIME,

CASE WHEN CTE4.INOUT = 2 THEN CTE4.DateTime END AS INOUT_OUTTIME

From

CTE4

),

cte2

as

(

select cte1.EmpID, Date, MAX(INOUT_INTIME) AS INTIME,

MAX(INOUT_OUTTIME) AS OUTTIME

, DATEDIFF(Hour, MAX(INOUT_INTIME), MAX(INOUT_OUTTIME)) as [Hours]

FROM CTE1

GROUP BY EmpID, [Date]

)

select cte.EmpName, cte2.EmpID,cte.OTEntitled, cte2.INTIME, cte2.OUTTIME, cte2.[Hours]

, CASE WHEN cte2.[Hours] >= 8 THEN 1

WHEN cte2.[Hours] = 0 THEN 0

WHEN cte2.[Hours] >= 6 THEN 0.5 END AS [Day],

CASE WHEN cte2.[Hours] > 8 then cte2.[Hours] - 8 else 0 End as OT,

CASE when cte.OTEntitled = 'Yes'

cte2.[Hours] >= 8

THEN ( cte2.[Hours] - 8) * 100 else 0 END AS OTAMount,

Convert(varchar(10), cte2.INTIME,108) as [Time],

Case When Convert(Time, cte2.INTIME,108) > '09:10' Then 1 else 0 end as Late

from cte2

Right outer Join cte ON cte.EmpId= cte2.EmpID
