Connecting two queries into one - tsql

Question

I got such two queries:
SELECT
count (C.CaseDetailsId) as [Z telefonem]
,U.FirstName + ' ' + U.LastName as [Windykator]
from CaseDetails as C
join DebtorDetails as D on C.CaseDetailsId = D.CaseDetailsId
join Users as U on C.UserId = U.UserId
where D.DebtorDetailsId in
(SELECT DebtorDetailsId from DebtorPhone
where (IsValid = 'True') or (IsDefault = 'True'))
and C.CaseStatusId <> 2 and C.CaseStatusId <> 6 group by U.FirstName,U.LastName
e
and
SELECT
count (CaseDetailsId) as [Beztel]
,U.FirstName + ' ' + U.LastName as [Windykator]
from CaseDetails as C
join Users as U on C.UserId = U.UserId
where
C.CaseStatusId <> 2 and C.CaseStatusId <> 6 group by U.FirstName,U.LastName
I need to group the results of those two into 1 table so I suppose it would be best to connect them but I have no idea how to do it.
The query has to count rows in two cases
1) overall
2) where exists a specified row in another table
So in general -> I need to count number of cases (CaseDetailsId) for every employeer (Users) with and without phone number (DebtorPhones)

Answer 1

Below query will give you one record set from two queries using union. You can add insert statement above select to insert into your required table.
SELECT Count (C.casedetailsid) AS [Z telefonem],
U.firstname + ' ' + U.lastname AS [Windykator]
FROM casedetails AS C
JOIN debtordetails AS D
ON C.casedetailsid = D.casedetailsid
JOIN users AS U
ON C.userid = U.userid
WHERE D.debtordetailsid IN (SELECT debtordetailsid
FROM debtorphone
WHERE ( isvalid = 'True' )
OR ( isdefault = 'True' ))
AND C.casestatusid <> 2
AND C.casestatusid <> 6
GROUP BY U.firstname,
U.lastname
Union
SELECT Count (casedetailsid) AS [Z telefonem],
U.firstname + ' ' + U.lastname AS [Windykator]
FROM casedetails AS C
JOIN users AS U
ON C.userid = U.userid
WHERE C.casestatusid <> 2
AND C.casestatusid <> 6
GROUP BY U.firstname,
U.lastname

#Pratik Kaje not really. It shows 2 columns only - [Z tel] and [Windykator]
I tested a bit and ended with such query:
SELECT
[Windykator]
,[Beztel]
,[Z telefonem]
from
(SELECT
count (C.CaseDetailsId) as [Z telefonem]
,NULL as [Beztel]
,NULL as [Windykator]
from CaseDetails as C
join DebtorDetails as D on C.CaseDetailsId = D.CaseDetailsId
join Users as U on C.UserId = U.UserId
where D.DebtorDetailsId in
(SELECT DebtorDetailsId from DebtorPhone
where (IsValid = 'True') or (IsDefault = 'True'))
and C.CaseStatusId <> 2 and C.CaseStatusId <> 6
group by U.FirstName, U.LastName
UNION ALL
SELECT
NULL
,count (CaseDetailsId) as [Beztel]
,NULL
from CaseDetails as C
join Users as U on C.UserId = U.UserId
where
C.CaseStatusId <> 2 and C.CaseStatusId <> 6
group by U.FirstName, U.LastName
UNION ALL
SELECT
NULL
,NULL
,U.FirstName + ' ' + U.LastName
from CaseDetails as C
join Users as U on C.UserId = U.UserId
where
C.CaseStatusId <> 2 and C.CaseStatusId <> 6
group by U.FirstName, U.LastName
) as x
Almost perfectly however the results are not grouped. So it shows results with
NULLS NULLS [Bez tel]
NULLS [Z tel] NULLS
[Windykator] NULLS NULLS
