Hi Rishabh, why you made the join on: E.EMP_ID = Emp_CTE.MANAGER_ID. Pls explain once.
In MS _SQL if you have iteration more than 100, you have to specify OPTION (maxrecursion 0) ....WITH CTE_Date
AS
(
SELECT @StartDate 'dt'
UNION ALL
SELECT DATEADD(DD,1,dt) FROM CTE_Date
WHERE DATEADD(DD,1,dt) < @EndDate
)
INSERT INTO @DateSeries
SELECT * FROM CTE_Date
OPTION (maxrecursion 0)
hi Rishabh, kindly drop me your official mail id
