Question

Given two times, how do i insert one row per hour in the Oracle table?

Start Time: 3.00 PM

End Time: 6.00 PM

Name: 'Asdfg'

Expected Data to be generated:

Name      StartTime       EndTime
ASDFG       3.00           4.00
ASDFG       4.00,          5.00
ASDFG       5.00           6.00

Answer 1

This does it without PL/SQL, in one insert. You could parameterize the start and end times and use it in your procedure:

INSERT INTO tbl (NAME, starttime, endtime)
(SELECT 'ASDFG', t1, t2
   FROM (SELECT to_char((to_date('3.00 PM','HH.MI AM')+(LEVEL-1)/24),'HH.MI AM') t1
              , to_char((to_date('3.00 PM','HH.MI AM')+LEVEL/24), 'HH.MI AM') t2
           FROM dual 
        CONNECT BY LEVEL <= (to_date('6.00 PM','HH.MI AM') - to_date('3.00 PM','HH.MI AM')) * 24));
