SQL, the join did not return value 0

Hi Experts,

Query A returns 139 DealerIDs with their activeday.
Query B only return 38 DealerIDs, as some of 139 DealerID did not have 0 test drive # and their DealerID did not return.
How can I modify QUERY B, to show 139 DealerID and test drive # even the test drive # is 0. Thanks.

Currently, the Query B returns
DealerID   NAME   ACTIVEDAY   TESTDRIVE
BBB              YY             50                  5

I want Query B returns
DealerID   NAME   ACTIVEDAY   TESTDRIVE
AAA              XX             86                  0
BBB              YY             50                  5

QUERY A


select dealerid, dealershipName, count(dpd.date) as activeday
into #dealerwithactiveday
from [MMD_Feed].[dbo].[DealsPerDayHistoricalByType] dpd
where 
dpd.testdrive='Y'
and dealerid in (select dealerid from mmd_feed..dart)
group by dpd.dealerid,dpd.dealershipName

QUERY B

select dealerid, dealershipName, count(dpd.date) as activeday
into #dealerwithactiveday
from [MMD_Feed].[dbo].[DealsPerDayHistoricalByType] dpd
where 
dpd.testdrive='Y'
and dealerid in (select dealerid from mmd_feed..dart)
group by dpd.dealerid,dpd.dealershipName

select 
da.dealerid,
count(distinct d.dealid)as testdrive 
from mmd_feed..dart dt 
right join  #dealerwithactiveday da on da.dealerid=dt.dealerid
inner join Mmd_feed..dealview d on da.dealerid=d.dealerid 
inner join [MakeMyDeal_com].[dbo].[TestDrivelocal] t on t. dealid= d.dealid
where cast(d.submittedtimestamp as date)>=@StartDate and cast(d.submittedtimestamp as date)<=@EndDate
and d.dealstatus='sent'
and d.alternatedeal ='no'
and d.manualdeal='no'
group by da.dealerid

you would left join instead of inner join.

you may try this...

select 
da.dealerid,
count(distinct d.dealid)as testdrive 
from mmd_feed..dart dt 
right join  #dealerwithactiveday da on da.dealerid=dt.dealerid
inner join Mmd_feed..dealview d on da.dealerid=d.dealerid 
inner join [MakeMyDeal_com].[dbo].[TestDrivelocal] t on t. dealid= d.dealid
where cast(d.submittedtimestamp as date)>=@StartDate and cast(d.submittedtimestamp as date)<=@EndDate
and d.dealstatus='sent'
and d.alternatedeal ='no'
and d.manualdeal='no'
group by da.dealerid


Select a.*, case when isnull(b.testdrive, 0) testdrive
from #dealerwithactiveday a
left join 
(

select 
dt.dealerid
count(distinct d.dealid)as testdrive 
from mmd_feed..dart dt 
inner join Mmd_feed..dealview d on dt.dealerid=d.dealerid 
inner join [MakeMyDeal_com].[dbo].[TestDrivelocal] t on t.dealid= d.dealid
where cast(d.submittedtimestamp as date)>=@StartDate and cast(d.submittedtimestamp as date)<=@EndDate
and d.dealstatus='sent'
and d.alternatedeal ='no'
and d.manualdeal='no'
group by dt.dealerid

)
b
on a.dealerid = b.dealerid
