Display mgrno, and salary exlude groups where sal 1000 sort in desc.

Question

Since we are all on a roll and you guys rock I have 3 more left. If I didn't have this help I would fail this college course becuase i had 55 problems to do and these were the end of the class problems that I had no idea how to do them. I really appricate the help.
From what I already know:
ORDER BY MIN(SAL) DESC
I need to display the manager number and the salary of the lowest paid employee for that manager. Exclude anyone whose manager is not know-n. Exclude any groups where the minimum salary is less than $1000. Sort the output in descending order of salary.
          MGR     MIN (SAL)
          7566          3000
          7839          2450
          7782          1300
          7788          1100

You should treat every one for doing your homework
Right Eric :-)
Here we go
SQL>  SELECT a.mgr,min(a.sal)
  2   from emp a,emp b
  3   where a.mgr=b.empno
  4   GROUP BY A.MGR
  5   ORDER BY 2 DESC
  6   
SQL>  
SQL> /
       MGR MIN(A.SAL)
      7566       3000
      7839       2450
      7782       1300
      7788       1100
      7698       1045
      7902        880
