is there a better method to retrieve all the rows with dates in the current month.
select * from mytable where extract(month from mydate) = extract(month from now()) and extract(year from mydate) = extract(year from now());
Sorry; I was not thinking clearly - date_trunc is better for this:
select * from mytable where date_trunc('month',mydate) = date_trunc('month',now());
I have some code that uses extract() for this sort of thing. Would you mind explaining how date_trunc() is better for this?
Most of my extract() results end up in <select> drop-down boxes in HTML.
Thanks.
Colin
