postgresqlHow do I set a timestamp in PostgreSQL?
PostgreSQL provides two timestamp data types: timestamp
and timestamptz
.
The timestamp
data type stores the date and time information without any timezone information. The timestamptz
data type stores the date and time information including the timezone information.
To set a timestamp in PostgreSQL, you can use the to_timestamp
function.
For example, to set a timestamp
with the value 2020-07-14 12:00:00
:
SELECT to_timestamp('2020-07-14 12:00:00', 'YYYY-MM-DD HH24:MI:SS');
Output example
2020-07-14 12:00:00
To set a timestamptz
with the value 2020-07-14 12:00:00
:
SELECT to_timestamp('2020-07-14 12:00:00', 'YYYY-MM-DD HH24:MI:SS')::timestamptz;
Output example
2020-07-14 12:00:00+00
The to_timestamp
function takes two parameters:
- The timestamp value in
YYYY-MM-DD HH24:MI:SS
format. - The format of the timestamp value.
For more information, please refer to the PostgreSQL documentation.
