How to get the date and time in Oracle?

Get the Date and/or Time in Oracle:

SELECT SYSDATE FROM DUAL;

You can get the current date and/or time in per-second resolution using the SYSDATE function.
Caveats: The resolution of the time returned is 1 second. If you want sub-second resolution, you need to use SYSTIMESTAMP.

Store the Oracle Date and/or Time in Seconds:

CREATE TABLE mytable ( DATE(9) mydatetime, VARCHAR2(30) mycomment ); INSERT INTO mytable VALUES (SYSDATE, "This is the time that I ran the insert statement.");

In order to keep a SYSDATE value in the database, you need to use the column type DATE.
Caveats: The resolution of the time returned is 1 second. If you want sub-second resolution, you need to use SYSTIMESTAMP.

See the Oracle Date and/or Time in Seconds:

SELECT TO_CHAR(SYSDATE, 'DD-MM-YYYY HH24:MI:SS') FROM mytable;

In order to see a SYSDATE/DATE value, you can use the TO_CHAR function.
Format Models include ...
- DD = Date (number).
- MM = Month (number).
- YYYY = Year (number).
- HH24 = Hour (24 hour time).
- MI = Minutes.
- SS = Seconds (integral).
Caveats: The resolution of the time returned is 1 second. If you want sub-second resolution, you need to use SYSTIMESTAMP.
