--- order by

The `order by' clause lets you specify the sequence of the rows
   that result from a query.

The default sort sequence is ascending, with STRING fields sorted
   in alphabetic order form A to Z.

EXAMPLE: 
	  sql> select number, name, job
	  sql> from emp
	  sql> order by number/

You can sort by more than one field, and specify the direction, whether
   ascending (`asc') or descending (`desc'), for each field in the sort.

EXAMPLE:
          sql> select dept_no, name, job
	  sql> form emp
	  sql> order by dept_no desc, name asc/
