Ok, I have this date string:
2016-05-31T23:00:00.000Z
I want to be able to use it to search on a date in an Oracle 12c table, for example
SELECT stuff
FROM TABLE
WHERE date_column > TO_DATE('2016-05-31T23:00:00.000Z', 'what goes here?');
I can't figure out what format this date is in, can anyone help? This is probably simple, but I can't seem to find it...
Edit: this isn't C#
If you need the string representing UTC converted to your local time zone then you need to do a few steps. The starting point is to use to_timestamp()
with character literals for the T and Z, which Oracle doesn't recognise:
select to_timestamp('2016-05-31T23:00:00.000Z', 'YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"')
from dual;
TO_TIMESTAMP('2016-05-31T23:00:00.000Z','YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"')
-------------------------------------------------------------------------
2016-05-31 23:00:00.000
Then you can state that timezone-less value is actually UTC with from_tz()
:
select from_tz(
to_timestamp('2016-05-31T23:00:00.000Z', 'YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"'),
'UTC')
from dual;
FROM_TZ(TO_TIMESTAMP('2016-05-31T23:00:00.000Z','YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"'
--------------------------------------------------------------------------------
2016-05-31 23:00:00.000 UTC
Then you can convert it to your own time zone:
select from_tz(
to_timestamp('2016-05-31T23:00:00.000Z', 'YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"'),
'UTC') at time zone 'Europe/London'
from dual;
FROM_TZ(TO_TIMESTAMP('2016-05-31T23:00:00.000Z','YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"'
--------------------------------------------------------------------------------
2016-06-01 00:00:00.000 EUROPE/LONDON
If you want it back as a date datatype you can cast it:
select cast(from_tz(
to_timestamp('2016-05-31T23:00:00.000Z', 'YYYY-MM-DD"T"HH24:MI:SS.FF3"Z"'),
'UTC') at time zone 'Europe/London' as date)
from dual;
CAST(FROM_TZ(TO_TIMESTAMP('2016-05-31T23:00:00.000Z','YYYY-MM-DD"T"HH24:MI:SS.FF
--------------------------------------------------------------------------------
