HOUR_SECOND

MySQL

Example

SELECT CURTIME() as 'Current Time',
       DATE_FORMAT(CURTIME(),'%H:%i:%s') as 'Hour:Minute:Second';

Output

| Current Time | Hour:Minute:Second |
| ------------ | ------------------ |
|  12:34:56    |     12:34:56       |

Explanation

In this example, the CURTIME() function is used to get the current time. The DATE_FORMAT() function formats the date as hours (H), minutes (i), and seconds (s). The result is a table that displays the default format of CURTIME() and the formatted time.

SQL Server

Example

SELECT CONVERT(VARCHAR, GETDATE(), 108) AS Current_Time

Output

Current_Time
------------
14:30:23

Explanation

In this SQL query, the function GETDATE() returns the current system date and time in SQL Server. The CONVERT function then formats this datetime value into a string that only includes the hours, minutes, and seconds (HH:MM:SS).

Oracle

Oracle SQL does not support ‘HOUR_SECOND’ as it is a date format in MySQL. However, you can use extract function in Oracle to get the hour and second from a timestamp.

Example

SELECT EXTRACT(HOUR FROM timestamp) AS HOUR, EXTRACT(SECOND FROM timestamp) AS SECOND
FROM (
  SELECT TO_TIMESTAMP('2022-12-25 10:21:33', 'YYYY-MM-DD HH24:MI:SS') AS timestamp
  FROM dual
);

Output

HOUR     SECOND
-----    ------
10       33

Explanation

In the above example, EXTRACT function is being used to fetch the hour and second from a given timestamp. The TO_TIMESTAMP function is used to convert a string into a timestamp.
