Assuming this is SQL/Server 7, use the SELECT TOP option
to select the top 5 in each department in a correlated subselect --
select *
from scott.employee X
where salary in
(select top 5 salary
from scott.employee
where dept = X.dept
order by salary desc)
order by dept, salary desc
Sorry, I'm not 100% sure this will work because I
do not have access to SQL/Server to test this.
I'm not certain the syntax for referring to scott's employee table
is correct.
Note that the ORDER BY in the subselect is descending, so that
the TOP function will pick the five highest salaries. The ORDER BY
in the outer query sorts the results by highest salaries within department.
By the way, both I and Craig Mullins, another of searchDatabase.com's
database experts,
have written web page articles which discuss the "Top Ten" problem --

Mine's a little older and does not discuss SELECT TOP.
