How to create or combine three CTE - sql-server

Question

I hope you can help/guide me, I have one working CTE and I would like to add two more SQL queries to have one SQL statement and I am encountering various type of error as I try to play around with the parameters...
I have less experience in CTE so please bear with me...my purpose is to create an SSRS report using report builder and I want to combine the output of each query into a column bar...
Here is the working CTE which is my first Column Bar in my SSRS report...
WITH Cnt AS (
select Count(Distinct UserID) as Entitled_Users, DATEFROMPARTS(YEAR(t.WhenAddedToGroup),MONTH(t.WhenAddedToGroup),1) as When_Added_To_Group
from Membership t
where FirstName not like '%test%' and LastName not like '%test%' and FirstName not like '%user%' and LastName not like '%user%' and Account_Disabled not like 'YES' and Obj_Type not like 'NON_USER' and Region not like 'EMEA' and Region not like 'CCLA' and SecGroup IN ('SecurityGroup1', 'SecurityGroup2', 'SecurityGroup3', 'SecurityGroup4')and curr_member like 'yes' and ATTUID is not null and WhenAddedToGroup is not null
Group By DATEFROMPARTS(YEAR(t.WhenAddedToGroup),MONTH(t.WhenAddedToGroup),1)
)
Select When_Added_To_Group, Entitled_Users, (Select SUM(t2.Entitled_Users) as Entitled_Users
from Cnt T2
where T2.When_Added_To_Group <=T1.When_Added_To_Group) as Running_Total
from Cnt T1
Below is the second SQL query that I am hoping I can merge or join with the above CTE which will be the second column bar of my Column Report in SSRS..
SELECT c.EventType, DATEFROMPARTS(YEAR(c.Event_Date),MONTH(c.Event_Date),1) as Concurrent_Date, MAX(c.MAX_Concurrent_Users) as Peak_Concurrent_Users, c.Hub
FROM vNon_Concurrent_Users c
where c.EventType like 'Broker_Daily_Max_Users' and c.Hub like 'TOK Hub'
group by DATEFROMPARTS(YEAR(c.Event_Date),MONTH(c.Event_Date),1), c.Hub, c.EventType
below is my third SQL Query which will be the third column bar of my SSRS report...
select hs.hub, hs.NAME, DATEFROMPARTS(YEAR(hs.BOOT_TIME),MONTH(hs.BOOT_TIME),1) as Host_Boot_Time,
ROUND(CAST(hs.CPU_CORE_COUNT as FLOAT)*hs.CPU_Hz*count(cast(hs.HOSTID as BIGINT))/800000000,0) as Host_Capacity
from HVD_VPXV_HOSTS as hs WITH (NOLOCK,NOWAIT)
where hs.hub like 'TOK Hub'
group by hs.hub, hs.CPU_CORE_COUNT, hs.CPU_Hz, hs.NAME, hs.BOOT_TIME
order by hs.BOOT_TIME desc
the where clause of the three queries are:
When_Added_To_Group=Concurrent_date,
When_Added_To_Group=Host_Boot_time
as mentioned above I tried playing around with the paramters but I get different errors...below is one (of many) statement which I tried that I can give as an example:
WITH Cnt AS (
select Count(Distinct UserID) as Entitled_Users, DATEFROMPARTS(YEAR(t.WhenAddedToGroup),MONTH(t.WhenAddedToGroup),1) as When_Added_To_Group
from HVDMembership t
where FirstName not like '%test%' and LastName not like '%test%' and FirstName not like '%user%' and LastName not like '%user%' and Account_Disabled not like 'YES' and Obj_Type not like 'NON_USER' and Region not like 'EMEA' and Region not like 'CCLA' and SecGroup IN ('SecurityGroup1', 'SecurityGroup2', 'SecurityGroup3', 'SecurityGroup4')and curr_member like 'yes' and ATTUID is not null and WhenAddedToGroup is not null
Group By DATEFROMPARTS(YEAR(t.WhenAddedToGroup),MONTH(t.WhenAddedToGroup),1)
)
, Concurrent
as (
SELECT c.EventType, DATEFROMPARTS(YEAR(c.Event_Date),MONTH(c.Event_Date),1) as Concurrent_Date, MAX(c.MAX_Concurrent_Users) as Peak_Concurrent_Users, c.Hub
FROM vNon_Concurrent_Users c
where c.EventType like 'Broker_Daily_Max_Users' and c.Hub like 'TOK Hub'
group by DATEFROMPARTS(YEAR(c.Event_Date),MONTH(c.Event_Date),1), c.Hub, c.EventType
)
, Capacity
as (
select hs.hub, hs.NAME, DATEFROMPARTS(YEAR(hs.BOOT_TIME),MONTH(hs.BOOT_TIME),1) as Host_Boot_Time,
ROUND(CAST(hs.CPU_CORE_COUNT as FLOAT)*hs.CPU_Hz*count(cast(hs.HOSTID as BIGINT))/800000000,0) as Host_Capacity
from HVD_VPXV_HOSTS as hs WITH (NOLOCK,NOWAIT)
where hs.hub like 'TOK Hub'
group by hs.hub, hs.CPU_CORE_COUNT, hs.CPU_Hz, hs.NAME, hs.BOOT_TIME
)
Select When_Added_To_Group, Entitled_Users, (Select SUM(t2.Entitled_Users) as Entitled_Users
from Cnt T2
where T2.When_Added_To_Group <=T1.When_Added_To_Group) as Running_Total,
Select Peak_concurrent_users, concurrent_date from Concurrent,
select SUM(Host_Capacity), Host_Boot_Time from Capacity
where When_Added_To_Group=Concurrent_date, When_Added_To_Group=Host_Boot_time
from Cnt T1
Thanks in advance.

Answer 1

CTEs must be referenced only in the first SQL statement after the CTE. You have multiple selects. That is your first problem.
The second problem is that your CTEs don't appear to have data that is related to each other. Without knowing what you would expect as the results from sample data, it is pretty much impossible to advise you on how you should do the query. I can't make any meaning out of what you are trying to do, so I don't know what query you want to write. I could randomly suggest 3-4 different alternative queries but that would likely be less useful to you than asking you to provide information on what you are trying for and what your business rules should be and sample data. You simply cannot effectively write queries without understanding the underlying meaning of the data.
