Hello,
I have a table with a timestamp column and I want to set this to a value
of now() - a random number of days between 0 and 45 for each row... I've
tried to do this a bunch of different ways and can't figure it out...
Here is my latest version:
update sometable set entered_dt = now() -
Err, I just read my latest digest and saw the solution:
update datafrenzy.jobdata set entered_dt= now() - CAST(round(random()*45)
|| ' days' AS interval);

Or one of the following (add round() if desired):
select now() - 45 * random() * interval'1 day';
select now() - random() * interval'45 day';
