I am counting redirects from my login system to different applications and all my counts are grouped vertically. How do i get the result horisontally grouped by each application?

I Want a result like this
App1: App2: App3
4: 7: 8

Im getting this

App1
4
7
8

Im on SQL server 2014

What I have tried:

(SELECT COUNT(REDIRTO) AS App1
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName1%'
)
UNION
(
SELECT COUNT(REDIRTO) AS App2
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName2%'
)
UNION
(
SELECT COUNT(REDIRTO) AS App3
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName3%'
)

Another solution could be:

SQL

;with cte as 
((SELECT (case when REDIRTO like '%AppName1%' then 'AppName1'
			 when REDIRTO like '%AppName2%' then 'AppName2' 
			 when REDIRTO like '%AppName3%' then 'AppName3'	
		  end) as App, 
	COUNT(*) AS AppCount
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName[123]%' /* Note regular expression here*/
group by (case when REDIRTO like '%AppName1%' then 'AppName1'
			 when REDIRTO like '%AppName2%' then 'AppName2' 
			 when REDIRTO like '%AppName3%' then 'AppName3'	
		  end)
)
)
select * from cte
pivot (sum(AppCount) for App in (AppName1,AppName2,AppName3)) as FinalResult

Hello Kristian,

I don't know if I have understood well but I would say that you want to do something like this:

SQL

declare @Demo table (App nvarchar(20), Num int)

insert into @Demo(App, Num)
values('App1',20),('App2',30),('App3',40)

select * from @Demo
pivot (sum(Num) for App in (App1,App2,App3)) as Result

If so (if not, let me know or clarify please) , you can try a simple solution regarding your own code similar to:

SQL

;with cte as 
((SELECT 'AppName1' as App, COUNT(REDIRTO) AS AppCount
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName1%'
)
UNION
(
SELECT 'AppName2' as App, COUNT(REDIRTO) AS AppCount
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName2%'
)
UNION
(
SELECT 'AppName3' as App, COUNT(REDIRTO) AS AppCount
FROM globallogin.Eventlog
WHERE (LOGONAS = 'my@email.com') AND REDIRTO LIKE '%AppName3%'
))
select * from cte
pivot (sum(AppCount) for App in (AppName1,AppName2,AppName3)) as FinalResult

I hope this is useful for you!

Anyway I didn't like so many 'UNION' operator in the Common Table Expression, later on I'll send you a new solution more optimized.
