How to extend the query to add 0 in the cell when no activity is performed

Question

I have the following query, it is working fine to show the cricket time played per day. All I need is to show 0 when no cricket is played. At the moment it is skipping those

Answer 1

Try this

;WITH CTE AS (
SELECT email, last_update, activity, starttime, endtime, duration as [Totaltime] from users 
WHERE activity='cricket' and email='abc'
GROUP BY email, activity, duration, starttime, endtime, last_update
)
select activity, cast(starttime as date) as date,
SUM(datediff(second, starttime, endtime))/60.0 as TimePerDay
into #tempcte
from CTE
--where starttime >= dateadd(day, -15, last_update)
group by activity, cast(starttime as date)

select * from #tempcte

DECLARE @startDate date = (select min([date]) from #tempcte)
DECLARE @endDate date = (select max([date]) from #tempcte)
;WITH dates(Date) AS 
(
    SELECT @startdate as Date
    UNION ALL
    SELECT DATEADD(d,1,dates.Date)
    FROM dates 
    WHERE dates.Date < @enddate --and dates.Date not in (select [date] from #tempcte)
)
--select * from dates
Select activity, [date], TimePerDay
from #tempcte
union
select 'cricket' activity, [Date] as Date, 0 as TimePerDay FROM dates where dates.Date not in (select [date] from #tempcte)

drop table #tempcte
