Oracle Convert Seconds to Hours:Minutes:Seconds

Question

I have a requirement to display user available time in Hours:Minutes:Seconds format from a given total number of seconds value. Appreciate if you know a ORACLE function to d

Answer 1

Convert minutes to hour:min:sec format

SELECT 
   TO_CHAR(TRUNC((MINUTES * 60) / 3600), 'FM9900') || ':' ||
   TO_CHAR(TRUNC(MOD((MINUTES * 60), 3600) / 60), 'FM00') || ':' ||
   TO_CHAR(MOD((MINUTES * 60), 60), 'FM00') AS MIN_TO_HOUR FROM DUAL

Answer 2

If you're just looking to convert a given number of seconds into HH:MI:SS format, this should do it

SELECT 
    TO_CHAR(TRUNC(x/3600),'FM9900') || ':' ||
    TO_CHAR(TRUNC(MOD(x,3600)/60),'FM00') || ':' ||
    TO_CHAR(MOD(x,60),'FM00')
FROM DUAL

where x is the number of seconds.

The following is Yet Another Way (tm) - still involves a little calculation but provides an example of using EXTRACT to pull the individual fields out of an INTERVAL:

DECLARE 
  SUBTYPE BIG_INTERVAL IS INTERVAL DAY(9) TO SECOND;

  i        BIG_INTERVAL;
  nSeconds NUMBER := 86400000;

  FUNCTION INTERVAL_TO_HMS_STRING(inv IN BIG_INTERVAL)
    RETURN VARCHAR2
  IS
    nHours    NUMBER;
    nMinutes  NUMBER;
    nSeconds  NUMBER;
    strHour_format  VARCHAR2(10) := '09';
    workInv   INTERVAL DAY(9) TO SECOND(9);
  BEGIN
    nHours := EXTRACT(HOUR FROM inv) + (EXTRACT(DAY FROM inv) * 24);
    strHour_format := TRIM(RPAD(' ', LENGTH(TRIM(TO_CHAR(ABS(nHours)))), '0') || '9');

    nMinutes := ABS(EXTRACT(MINUTE FROM inv));
    nSeconds := ABS(EXTRACT(SECOND FROM inv));

    RETURN TRIM(TO_CHAR(nHours, strHour_format)) || ':' ||
           TRIM(TO_CHAR(nMInutes, '09')) || ':' ||
           TRIM(TO_CHAR(nSeconds, '09'));
  END INTERVAL_TO_HMS_STRING;

BEGIN
  i := NUMTODSINTERVAL(nSeconds, 'SECOND');

  DBMS_OUTPUT.PUT_LINE('i (fields) = ' || INTERVAL_TO_HMS_STRING(i));
END;

The code which extracts the fields, etc, still has to contain a calculation to convert the DAY field to equivalent hours, and is not the prettiest, but wrapped up neatly in a procedure it's not too bad to use.

Share and enjoy.

Answer 4

If you have a variable containing f.e. 1 minute(in seconds), you can add it to the systimestamp then use to_char to select the different time parts from it.

select to_char(systimestamp+60/(24*60*60), 'yyyy.mm.dd HH24:mi:ss') from dual

Answer 5

My version. Show Oracle DB uptime in format DDd HHh MMm SSs

select to_char(trunc((((86400*x)/60)/60)/24)) || 'd ' ||
   to_char(trunc(((86400*x)/60)/60)-24*(trunc((((86400*x)/60)/60)/24)), 'FM00') || 'h ' ||
   to_char(trunc((86400*x)/60)-60*(trunc(((86400*x)/60)/60)), 'FM00') || 'm ' ||
   to_char(trunc(86400*x)-60*(trunc((86400*x)/60)), 'FM00') || 's' "UPTIME"
 from (select (sysdate - t.startup_time) x from V$INSTANCE t);

Answer 6

The following code is less complex and gives the same result. Note that 'X' is the number of seconds to be converted to hours.

In Oracle use:

SELECT TO_CHAR (TRUNC (SYSDATE) + NUMTODSINTERVAL (X, 'second'),
                'hh24:mi:ss'
               ) hr
  FROM DUAL;

In SqlServer use:

SELECT CONVERT(varchar, DATEADD(s, X, 0), 108);
