Oracle SYSTIMESTAMP

The Oracle SYSTIMESTAMP function returns a TIMESTAMP WITH TIME ZONE value that represents the system date and time including fractional seconds and time zone.

Syntax

The Oracle SYSTIMESTAMP function accepts no argument:

SYSTIMESTAMP</code>
Code language: HTML, XML (xml)

Return Value

The Oracle SYSTIMESTAMP function returns a TIMESTAMP WITH TIME ZONE value that represents the system date.

Examples

The following statement shows the returned value of the SYSTIMESTAMP function:

SELECT
  SYSTIMESTAMP
FROM
  dual;
Code language: SQL (Structured Query Language) (sql)

Here is the result:

07-AUG-17 01.08.16.408000000 PM -07:00
Code language: SQL (Structured Query Language) (sql)

To specify the value for fractional second argument e.g., 2-digit, you use the TO_CHAR() function as follows:

SELECT
  TO_CHAR(SYSTIMESTAMP,'DD-MON-YYYY HH24:MI:SS.FF2 TZH:TZM')
FROM
  dual; 
Code language: SQL (Structured Query Language) (sql)

The output is a character string with the following format:

07-AUG-2017 13:24:13.44 -07:00
Code language: SQL (Structured Query Language) (sql)

Noted that we used FF2 to format the timestamp with 2 digits for fractional second precision.

In this tutorial, you have learned how to use the Oracle SYSTIMESTAMP function to get a TIMESTAMP WITH TIME ZONE value that represents the system date and time including fractional seconds and time zone.
