Return Date got no hour and minutes returned

问题

This is my code

CREATE OR REPLACE FUNCTION GET_DATE(P_DAYS IN  NUMBER) RETURN DATE AS
  V_DATE DATE;
BEGIN
  V_DATE := SYSDATE+P_DAYS;
  DBMS_OUTPUT.PUT_LINE(TO_CHAR(V_DATE, 'YYYY-MM-DD HH24:MI:SS'));
  RETURN V_DATE;
END;
/

My output:

GET_DATE(2)
-----------
2015-03-12
2015-03-12 19:26:14

How do i get minutes, hours and seconds returned ? i want the answer to be like the dbms_output does...

I think you need to do something like this:

CREATE OR REPLACE FUNCTION GET_DATE(p_days IN NUMBER) RETURN VARCHAR2 AS
    v_date VARCHAR2(30);
BEGIN
    v_date := TO_CHAR(SYSDATE + p_days, 'YYYY-MM-DD HH24:MI:SS');
    RETURN v_date;
END;
/
