A

Each column in the query output has a default name. If you don't like the default name, you can specify a new name for any column in the query output by using the AS clause. The following statement shows you a good example:

SQL> SELECT department_id AS ID, MIN(salary) AS Low, 
  2  MAX(salary) AS High, AVG(salary) AS Average 
  3  FROM employees GROUP BY department_id 
  4  HAVING AVG(salary) < 5000;
        ID        LOW       HIGH    AVERAGE
---------- ---------- ---------- ----------
        30       2500      11000       4150
        50       2100       8200 3475.55556
        10       4400       4400       4400
