Question

I am trying to achieve selecting from a table with random date ranges. Something like

SELECT * FROM my_table WHERE timestamp 
BETWEEN <random_date> AND <the_same_random_date> - INTERVAL 1 DAY

That way I should be selecting an interval of 1 day of a random date. Any suggestions?

Update: So the random queries might has the same effect as following ones:

SELECT * FROM my_table WHERE timestamp 
BETWEEN '2011-08-05 00:00' AND '2011-08-05 00:00' - INTERVAL 1 DAY

SELECT * FROM my_table WHERE timestamp 
BETWEEN '2011-08-12 14:30' AND '2011-08-12 14:30' - INTERVAL 1 DAY

SELECT * FROM my_table WHERE timestamp 
BETWEEN '2011-05-11 06:15' AND '2011-05-11 06:15' - INTERVAL 1 DAY

SELECT * FROM my_table WHERE timestamp 
BETWEEN '2011-03-03 21:11' AND '2011-03-03 21:11' - INTERVAL 1 DAY

SELECT * 
FROM 
    my_table
    CROSS JOIN (SELECT FROM_UNIXTIME(RAND() * 2147483647) random_date) rd
WHERE 
    timestamp BETWEEN (rd.random_date - INTERVAL 1 DAY) AND rd.random_date
