Query to get the Number of Seconds or Minutes or Hours between 2 given days:-


For the Seconds:-
-------------------

SELECT ('Your first Date'-'Your another Date') * DECODE( UPPER('SS')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

Example:-

SELECT (SYSDATE+1-SYSDATE) * DECODE( UPPER('SS')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

For Minutes:-
---------------

SELECT ('Your first Date'-'Your another Date') * DECODE( UPPER('MI')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

Example:-

SELECT (SYSDATE+1-SYSDATE) * DECODE( UPPER('MI')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

For the Hours:-
-----------------

SELECT ('Your first Date'-'Your another Date') * DECODE( UPPER('HH')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

Example:-

SELECT (SYSDATE+1-SYSDATE) * DECODE( UPPER('HH')
, 'SS', 24*60*60
, 'MI', 24*60
, 'HH', 24, NULL )
FROM DUAL;

This is the simple decode function made for all the above 3 requirements. I hope this will help you.
