Re Count statement n times using the same column

Question

Hi All,
I am struggling with a query. I am using a column to count using a wildcard for 'N1%', I want to be able to also count for 'N2%' up to 'N5%' in the query.
My query is as follows:
SELECT s.name as name, count (cs.pri_comment_txt) as N1
FROM systems s, clientstate cs
WHERE cs.supportpriority is NOT NULL
AND cs.assignedname is null
AND s.systemid = cs.systemtype
AND cs.pri_comment_txt like 'N1%'
group by rollup (s.name)
Thanks inadvance
Regards

I think you mean something like this (untested)?
SELECT s.name as name
, count (case when cs.pri_comment_txt like 'N1%' then 1 else null end) as N1
, count (case when cs.pri_comment_txt like 'N2%' then 1 else null end) as N2
, count (case when cs.pri_comment_txt like 'N3%' then 1 else null end) as N3
, count (case when cs.pri_comment_txt like 'N4%' then 1 else null end) as N4
, count (case when cs.pri_comment_txt like 'N5%' then 1 else null end) as N5
from systems s
, clientstate cs
where cs.supportpriority is not null
and cs.assignedname is null
and s.systemid = cs.systemtype
and (
   cs.pri_comment_txt like 'N1%'
   or cs.pri_comment_txt like 'N2%'
   or cs.pri_comment_txt like 'N3%'
   or cs.pri_comment_txt like 'N4%'
   or cs.pri_comment_txt like 'N5%'
group by rollup (s.name);cheers,
