Question

I have folowing sql query

select sta_name Station,count(factory_name) as factories from gps1
group by sta_name
order by sta_name

Through this query i am getting only total factories in a single Station.Problem is that i want to get the the result in the shape that factory number should also dispalye out of total factories in Station For Exampel If a Station has 5 factoreies then Five Factories should have this output

1/5
2/5
3/5
4/5
5/5

Any one please help me to get this type of result
UPdate
I Want this output
for example i have 5 factories in a station station1

factoryName      Count
factroty 1        1/5
factroty 2        2/5
factroty 3        3/5
factroty 4        4/5
factroty 5        5/5

Answer 1

Turn the count into an analytic function and remove the grouping:

select sta_name Station,count(factory_name) over(partition by sta_name) as factories from gps1
order by sta_name

Of course, if you want it like 1/5 then change it to:

select sta_name||'/'||count(factory_name) over(partition by sta_name) as factories from gps1
order by sta_name

EDIT: To mark it as, say, ‘1 out of 5’, ‘2 out of 5’, etc. then you can add a row_number:

select   FACTORY_NAME
        ,   row_number() over (partition by STA_NAME order by STA_NAME)
         || '/'
         || count(STA_NAME) over (partition by STA_NAME)
           as FACTORIES
from     GPS1
order by FACTORY_NAME
