Question

I have table SR with some records with statuses (more then 5 records this is just example ):

ID   STATUS
1    NEW
2    OPEN
3    OPEN
4    PENDING
5    PENDING

I want to get table in this format:

STATUS   PERCENTAGE

NEW       20
OPEN      40
PENDING   40

I wrote SQL query but I can’t make it work:

with HELPTABLE as
(select count(*) as NUMBER
from SR
)
select 
    SR.STATUS,
    (count (*)) / (HELPTABLE.NUMBER) * 100
from 
    SR, HELPTABLE
group by 
    SR.status

Using HELPTABLE I am getting as result 5.

If I don’t put HELPTABLE.NUMBER I am getting some result.

If I divide (count (*)) with let’s say with 2 I am getting result, but if I put HELPTABLE.NUMBER which is 5 I am getting an error.

Thanks for help.

Answer 1

I’m guessing SQL Server 2005 or higher

select
     T.STATUS, 100.0 * COUNT(*) / Total
from
    (
     SELECT 
        ID, STATUS, COUNT(*) OVER () AS Total
     FROM
        SR
    ) T
group by 
     T.status, T.Total
