Oracle/PLSQL FROM_TZ function syntax

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
