To get the count of records and able to access the column value in a single

Question

Hi
Is there any way to get the number of records in the query and access the column values
e.g
select count(*)
from
(SELECT department, COUNT(*) as "Number of employees"
FROM employees
WHERE salary > 25000
GROUP BY department ) a
This wil only get the Count, if i want to access each row from the inline view how can i do that.

Your question is not clear.
Are you looking for total record count as well as count by department ?
Something like this?
SQL>
SQL> with temp as
  2  (
  3  select 1 dept ,10000 sal from dual union
  4  select 1 dept ,25100 sal from dual union
  5  select 1 dept ,30000 sal from dual union
  6  select 1 dept ,40000 sal from dual union
  7  select 2 dept ,10000 sal from dual union
  8  select 2 dept ,25100 sal from dual union
  9  select 2 dept ,30000 sal from dual union
10  select 2 dept ,40000 sal from dual )
11  select count(*) over( partition by 1 ) total_count,dept,
12  count(*) over(partition by dept) dept_cnt  from temp
13  where sal>25000;
TOTAL_COUNT       DEPT   DEPT_CNT
          6          1          3
          6          1          3
          6          1          3
          6          2          3
          6          2          3
          6          2          3
