Add the column's with Alias name in sql server - sql-server

Question

I have the below query -
select TeamProjectSK,
sum(case when d.System_State = 'Proposed' then 1 else 0 end) as New,
sum(case when d.System_State = 'Active' then 1 else 0 end) as Active,
sum(case when d.System_State = 'Resolved' then 1 else 0 end) as Resolved,
sum(case when d.System_State = 'Closed' then 1 else 0 end) as Closed
from
(
select w1.System_Id, w1.TeamProjectSK, w1.System_State, w1.System_Rev,
row_number() over(partition by w1.System_Id, w1.TeamProjectSK, w1.System_State order by w1.System_Rev desc) rn
from dbo.DimWorkItem w1
) d
where rn = 1
and d.System_Rev = (select max(w2.System_Rev) from dbo.DimWorkItem w2 where w2.System_Id = d.System_Id)
group by TeamProjectSK
order by TeamProjectSK desc;
The result of the query looks like -
TeamProjectSK New Active Resolved Closed
157 14 115 1 169
156 0 0 0 0
155 0 0 0 0
154 0 0 0 0
151 2 1 0 1
Now i want a column "Total_Count" which should be the sum of New+Active+Resolved+Closed. The output should look like -
TeamProjectSK Total_Count New Active Resolved Closed
157 289 14 115 1 169
156 0 0 0 0 0
155 0 0 0 0 0
154 0 0 0 0 0
151 4 2 1 0 1
I tried the below query, but it would not help. Please look into the same.
select TeamProjectSK,
New + Active + Resolved + Closed as Total_Count,
sum(case when d.System_State = 'Proposed' then 1 else 0 end) as New,
sum(case when d.System_State = 'Active' then 1 else 0 end) as Active,
sum(case when d.System_State = 'Resolved' then 1 else 0 end) as Resolved,
sum(case when d.System_State = 'Closed' then 1 else 0 end) as Closed
from
(
select w1.System_Id, w1.TeamProjectSK, w1.System_State, w1.System_Rev,
row_number() over(partition by w1.System_Id, w1.TeamProjectSK, w1.System_State order by w1.System_Rev desc) rn
from dbo.DimWorkItem w1
) d
where rn = 1
and d.System_Rev = (select max(w2.System_Rev) from dbo.DimWorkItem w2 where w2.System_Id = d.System_Id)
group by TeamProjectSK
order by TeamProjectSK desc;
Regards.

Answer 1

select TeamProjectSK, New + Active + Resolved + Closed as Total_Count, New Active, Resolved, Closed
from
(
select TeamProjectSK,
sum(case when d.System_State = 'Proposed' then 1 else 0 end) as New,
sum(case when d.System_State = 'Active' then 1 else 0 end) as Active,
sum(case when d.System_State = 'Resolved' then 1 else 0 end) as Resolved,
sum(case when d.System_State = 'Closed' then 1 else 0 end) as Closed
from
(
select w1.System_Id, w1.TeamProjectSK, w1.System_State, w1.System_Rev,
row_number() over(partition by w1.System_Id, w1.TeamProjectSK, w1.System_State order by w1.System_Rev desc) rn
from dbo.DimWorkItem w1
) d
where rn = 1
and d.System_Rev = (select max(w2.System_Rev) from dbo.DimWorkItem w2 where w2.System_Id = d.System_Id)
group by TeamProjectSK
) a
order by TeamProjectSK desc
