Обсуждение: Getting timestamp without milliseconds

Either date_trunc

eg, SELECT date_trunc('hour', TIMESTAMP '2001-02-16 20:38:40');
Result: 2001-02-16 20:00:00

Or format the timestamp as a string

select to_char(now(), 'yyyy-mm-dd HH24:MI:SS');

Hope that helps.

Cast to timestamp(0).

Here ya go:

test=> create table t1 (ts timestamp);
CREATE TABLE
test=> insert into t1 values (now());
INSERT 2106750874 1
test=> select ts from t1;
             ts
----------------------------
 2006-01-05 10:15:48.167951
(1 row)

test=> select cast (ts as timestamp(0)) from t1;
         ts
---------------------
 2006-01-05 10:15:48
(1 row)

test=> select ts::timestamp(0) from t1;
         ts
---------------------
 2006-01-05 10:15:48
