[GENERAL] function to find difference between in days between two dates

[Ashish Karalkar]

Hello all,

Is there any function to find  differences in days between two dates?


I am using 

select abs(current_date - '2007-06-15')
 
to get the desired result.
but I think there must be a function and I am missing it,
if so, can anybody please point me to that.


Thanks in advance

With regards
