How to output time instead of date in oracle?

@denis 

To output time instead of date in Oracle, you can use the TO_CHAR function to format a date column or expression as a time value.

For example, you can use the following query to select the current time in Oracle:

1
2

SELECT TO_CHAR(SYSDATE, 'HH24:MI:SS') AS current_time
FROM dual;

This query will return the current time in the format HH24:MI:SS (24-hour clock with hours, minutes, and seconds). You can customize the format string in the TO_CHAR function to display the time in a different format as needed.
