Oracle FROM_TZ function

19 July 2020

Oracle FROM_TZ function

The Oracle PLSQL FROM_TZ function converts the TIMESTAMP value to TIMESTAMP with the time zone value.

Oracle/PLSQL FROM_TZ function syntax

FROM_TZ( timestamp_value_id, time_zone_value_id )

Parameters or arguments

  • timestamp_value_id – value to be converted to TIMESTAMP with time zone value.
  • time_zone_value_id – the time zone is used to convert timestamp_value to TIMESTAMP with the time zone value.

The FROM_TZ function returns the value of TIMESTAMP WITH TIME ZONE.

FROM_TZ function can be used in the following Oracle/PLSQL versions

Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i

 

Let’s consider some examples of the FROM_TZ function and learn how to use the FROM_TZ function in Oracle PLSQL.

If you execute the next SQL query:

SELECT FROM_TZ(TIMESTAMP '2014-08-11 01:50:42', '5:00')
FROM dual;

You’ll get the next result:
11.08.14 01:50:42,000000000 +05:00

If you execute the next SQL query, and set the time zone to ‘-7: 00’:

SELECT FROM_TZ(TIMESTAMP '2014-08-11 01:50:42', '-7:00')
FROM dual;

You’ll get the next result:
11.08.14 01:50:42,000000000 -07:00
