Question

I have a simple query which get a list of all dates in a date range, and want to implement it in groovy.

select 
TO_DATE('01/23/2012','MM/DD/YYYY') + level -1
from 
dual connect by level < (TO_DATE('02/07/2012','MM/DD/YYYY') - TO_DATE('01/23/2012','MM/DD/YYYY'));

Result set is :

23-JAN-12
24-JAN-12
25-JAN-12
26-JAN-12
27-JAN-12
28-JAN-12
29-JAN-12
30-JAN-12
31-JAN-12
01-FEB-12
02-FEB-12
03-FEB-12
04-FEB-12
05-FEB-12

Can I do this using groovy or if not hibernate?

Answer 1

d1 = new Date("1/23/2012")
d2 = new Date("2/5/2012")
(d1..d2).each { println "${it} (${it.format('dd-MMM-yy').toUpperCase()})" }

Outputs:
