What about using
WHERE f BETWEEN '2012-04-23 00:00:00' AND '2012-04-24 00:00:00'?On 04/25/2012 09:52 AM, Jasen Betts wrote: On 2012-04-24, rihad <rihad@xxxxxxx> wrote:As PostgreSQL stores timestamps with a fractional part, does it mean that WHERE f BETWEEN '2012-04-23 00:00:00' AND '2012-04-23 23:59:59' might miss records with values of f equal to 23:59:59.1234 or so?yes, it does. BETWEEN doesn't work well for timestamps. you have to do it the long way f >= '2012-04-23 00:00:00' AND f < '2012-04-24 00:00:00' |
