@type varchar(20)
)
RETURNS @A TABLE (
stdate datetime,eddate datetime, PartName varchar(30),[Year] int
)
AS
BEGIN
if @type = 'daily'
begin
;with cte as
( select CONVERT(DATETIME,@startDate) AS DATE
UNION ALL
select Dateadd(dd,1,DATE) as date
from cte
where date <= @endDate - 1
)
insert into @a
SELECT DATE, DATE + 1 - 1, 'Day ' + CAST(DatePart(dd, DATE) as varchar(10)) as Week_NO_Of_Year, DatePart(yy, DATE) as [Year]
FROM CTE
--Group by 'Day ' + CAST(DatePart(dd, DATE) as varchar(10))
order by (DATE) ASC
OPTION (MAXRECURSION 0)
end
else if @type = 'Weekly'
begin
;with cte as
( select CONVERT(DATETIME,@startDate) AS DATE
UNION ALL
select Dateadd(dd,1,DATE) as date
from cte

SELECT MIN(DATE), MAX(DATE), 'Week ' + CAST(DatePart(ww, DATE) as varchar(10)) as Week_NO_Of_Year,DatePart(yy, DATE) as [Year]
FROM CTE
Group by 'Week ' + CAST(DatePart(ww, DATE) as varchar(10)), DatePart(yy, DATE)
order by MIN(DATE) ASC
