returned row number

Hi All,

I have a quick question.  Is there a simple way to access the returned record
number?

I want to be able to do something like

SELECT record AS record_no,
       column1,
       column2
  FROM table1
 WHERE column2 < 100
 ORDER BY column1;

record_no | column1 | column2
----------+---------+---------
1         | A       | 1.75
2         | F       | 93
3         | M       | 12.5
4         | N       | 0
5         | Q       | 57.6

Kind Regards,
Keith
