Think of the math opperators '<' and '>' as 'before' and 'after',
respectively. ie:
SELECT * FROM table WHERE begin_date > '2004-07-06';
You can also use BETWEEN:
SELECT * FROM table WHERE update_timestamp BETWEEN '2004-07-01' AND
'2004-07-06';
Remember that when timestamps are cast to dates, they are cast with
00:00:00.0 as the time part.
