Categories:: Date & time functions

SECOND¶

Extracts the corresponding time part from a time, interval, or timestamp value.

These functions are alternatives to using the DATE_PART (or EXTRACT) function with the equivalent time part (see Supported date and time parts).

See also:: YEAR* / DAY* / WEEK* / MONTH / QUARTER

Syntax¶

HOUR( <time_interval_or_timestamp_expr> )

MINUTE( <time_interval_or_timestamp_expr> )

SECOND( <time_interval_or_timestamp_expr> )

Arguments¶

time_interval_or_timestamp_expr: A time, an interval, or a timestamp, or an expression that can be evaluated to one of those data types. An interval argument must be a day and time interval, not a year and month interval.

Returns¶

This function returns a value of type NUMBER.

Usage notes¶


Function name	Time part extracted from time, interval, or timestamp	Possible values
HOUR	Hour of the specified day	0 to 23
MINUTE	Minute of the specified hour	0 to 59
SECOND	Second of the specified minute	0 to 59

Tip

To extract a full TIME value from a TIMESTAMP value instead of a part, you can cast the TIMESTAMP value to a TIME value. For example:

SELECT '2025-04-08T23:39:20.123-07:00'::TIMESTAMP::TIME AS full_time_value;

+-----------------+
| FULL_TIME_VALUE |
|-----------------|
| 23:39:20        |
+-----------------+

Examples¶

This example demonstrates the HOUR, MINUTE, and SECOND functions:

SELECT '2025-04-08T23:39:20.123-07:00'::TIMESTAMP AS tstamp,
       HOUR(tstamp) AS "HOUR",
       MINUTE(tstamp) AS "MINUTE",
       SECOND(tstamp) AS "SECOND";

+-------------------------+------+--------+--------+
| TSTAMP                  | HOUR | MINUTE | SECOND |
|-------------------------+------+--------+--------|
| 2025-04-08 23:39:20.123 |   23 |     39 |     20 |
+-------------------------+------+--------+--------+
