Question

I wrote this function to get minutes from a date, but I cannot get minutes between two dates, How to get that ?

FUNCTION get_minute(p_date DATE)
RETURN NUMB         


        

Answer 1

For those who want to substrat two timestamps (instead of dates), there is a similar solution:

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 1440 AS minutesInBetween
FROM ...

or

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 86400 AS secondsInBetween
FROM ...
