    What do you mean by Julian date? According to Oracle's application of Julian's callendar today's date number is 2452767, not 127!
    Code:
    SQL> SELECT TO_CHAR(SYSDATE,'J') FROM dual;
    
    TO_CHAR
    -------
    2452767
    What you actualy mean is probably to get the today's day of the year number. For this you can use TO_CHAR() with 'DDD' format mask.
    Code:
    SQL> SELECT TO_CHAR(SYSDATE,'DDD') FROM dual;
    
    TO_

    Confusion here . . . IBM used to call a date YYDDD, "Julian" format . . . I'm sure Big Blue knows best.
