Sum a field without using field in group by statement- sql server 2008 SSRS

Question

I am trying to write a query as follows;
select todate, sum(entries) as A, sum(entries) as B  *(where dept=HR)
from table 1
where dept in(IT,HR)
group by todate
here A is summation of all the entries for dept IT and HR
and want to get B as summation of entries having dept HR only
Kindly note this sql would be used in ssrs 2008 dataset query.
Please help.

Hi, you can write it like this:
select todate, sum(entries) as A, SUM(CASE WHEN Dept = 'HR' THEN entries ELSE 0 END) as B
from table 1
where dept in('IT','HR')
group by todate
