Form a inline view based on the results of the previous query?

Posted on 16th Feb 2014 07:03 pm by admin

Hi Experts,
Can we form a inline view on the results of a previous query (another inline view)?

Ex:
select employees.emp_no,
employees.ename,
departments.dept_no
from
(select dept_no from dept) departments,
(select emp_no, ename from emp) employees
where employees.dept_no = departments.dept_no

In the above example, first the compiler forms 2 inline views employees and departments and then joins these 2 in the where clause.

But can we form the "employees" inline view to have only those rows based on the results of "departments" query.

Thanks
