LOCALTIMESTAMP

PostgreSQL

LOCALTIMESTAMP[(precision)]

• precision: This parameter defines the number of fractional digits retained in the seconds field. A value of 0 signifies second precision, while a maximum value of 6 signifies microsecond precision. The absence of a precision value defaults the digit precision to 6 in PostgreSQL. The precision value is optional for LOCALTIMESTAMP.

Example

SELECT LOCALTIMESTAMP;

Output

           localtimestamp

Oracle

LOCALTIMESTAMP [(precision)]

• precision: This optional parameter specifies the number of digits in the fractional part of the SECOND datetime field. It can range between 0 to 9. For example, LOCALTIMESTAMP(5) will give the local date and time down to a hundred thousandths of a second.

Example

SELECT LOCALTIMESTAMP FROM dual;

Output

27-SEP-21 03.41.32.798000000 PM

Explanation

The LOCALTIMESTAMP in Oracle returns the current date and time in the local timezone of the database. In the example, it is used in a SELECT statement to return the value from the dual table, a dummy table in Oracle.
