Getting the count of resultset along with result rows

I have a SQL query for which I needed to have result rows count and results as the output of query.

For example,

SELECT count(*) total, id, name, age, grade
FROM Employee
where grade = 10;

It prints only one row with total count. Please let me know what could be missing in query.

With GROUP BY:

Table:

id  name    age grade
1   ABC     30  10
2   DEF     31  10
3   GHI     29  6
4   PQR     29  10

Query:

SELECT count(*) total, id, name, age, grade
FROM Employee
where grade = 10
group by id, name, age, grade

total   id  name    age grade
1      1    ABC     30  10
1      2    DEF     31  10
1      4    PQR     29  10

Under total, I expect to have 3 as the value although it will be repeated. Here my intention is to have total row count and result rows as part of single query.
