Обсуждение: Changes to NOW() in 7.2?

Were there any changes to NOW() in 7.2? I see this in HISTORY:

now() returns time with millisecond precision (Thomas)

I have a query like this:

SELECT tour_dates.date, WHERE date_of_show >= NOW() ORDER BY date_of_show;

On 7.1.3, this query would include the current day as well as all dates in
the future. Since moving to 7.2, it only includes dates in the future...

I am using JDBC to access the data, if that makes any difference...

I don't believe it worked like that in 7.1.3 either --- at least not if
date_of_show is of type date.  NOW() is generally going to be later than
midnight, which is what a date promotes to when you compare it to a
timestamp.

test71=# select version();
                             version

(1 row)

test71=# create table foo (date_of_show date);
CREATE
test71=# insert into foo values ('today');
INSERT 1602743 1
test71=# select * from foo;
 date_of_show
--------------
 2002-03-04
(1 row)

test71=# select * from foo where date_of_show >= NOW();
 date_of_show
--------------
(0 rows)

What you probably want is CURRENT_DATE:

test71=# select * from foo where date_of_show >= current_date;
 date_of_show
--------------
 2002-03-04
(1 row)
