Retrieve data from the same table

Question

i have a table with following fields
emp_no,name,salary,department,dept_prev,prev_emp_no.
now i want retrieve emp_no,name,salary,department, from the data base for a perticular employeee number along with dept_prev
but dept_prev is the prev_emp_no dept_prev
now iam doing two query like this
first query to retreive name,salary,department
select name,salary,department from employee where emp_no = 10
second to retrieve the dept_prev from the same table but this
dept_prev must be based on prev_emp_no
select dept_prev from employee where emp_no in(select prev_emp_no from employee where emp_no =10)
can any one suggest to combine these two queries in a single sql statements, because all the fieldds are from the same table.
Thanks

Answer 1

Would this one solve it?
SELECT emp.NAME, emp.salary, emp.department,
       prev_emp.dept_prev
  FROM employee emp,
       employee prev_emp
WHERE emp.emp_no      = 10
   AND prev_emp.emp_no = emp.prev_emp_no;
