Hi,

I am trying to get the date with time zone in the below format (ISO 8601 I GUESS)

YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00)


where:
YYYY = four-digit year
MM = two-digit month (01=January, etc.)
DD = two-digit day of month (01 through 31)
hh = two digits of hour (00 through 23) (am/pm NOT allowed)
mm = two digits of minute (00 through 59)
ss = two digits of second (00 through 59)
s = one or more digits representing a decimal fraction of a second
TZD = time zone designator (Z or +hh:mm or -hh:mm)

Any help would really be appreciated.

Thank you

sysdate is the current date, and current time only.

systimestamp is what you want.

SQL> select sysdate from dual;

SYSDATE
---------
21-SEP-17

SQL> select systimestamp from dual;

SYSTIMESTAMP
---------------------------------------
21-SEP-17 08.42.33.222000 AM +08:00


You have total control over the output format 

SQL> select to_char(systimestamp,'YYYY-MM-DD hh24:mi:ss.ff TZR') from dual;

TO_CHAR(SYSTIMESTAMP,'YYYY-MM-DDHH24:MI:SS.FFTZR')
--------------------------------------------------------------
2017-09-21 08:46:24.752000 +08:00

glad we could help

"Date only" ..?

Isn't it a bit misleading to say "sysdate is the current date, and current date only."?

SQL> select to_char(sysdate, 'yyyy-mm-dd hh24:mi') as myDateAndTime from dual;

MYDATEANDTIME
----------------
2017-09-21 14:13

Sorry - typo on my part.

I've corrected the answer.

Not misleading at all really

If you look at the Oracle SQL Reference

https://docs.oracle.com/database/121/SQLRF/sql_elements001.htm#SQLRF0021

[..] Valid date range from January 1, 4712 BC, to December 31, 9999 AD. The default format is determined explicitly by the NLS_DATE_FORMAT parameter or implicitly by the NLS_TERRITORY parameter. The size is fixed at 7 bytes. This data type contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. It does not have fractional seconds or a time zone. [..]

Maybe Connor should have just capitalized "date" ;)

No - sorry, that was my bad typo.

"sysdate is the current date, and current date only. "

should have been:

"sysdate is the current date, and current time only."
