Question

Heyho,

I need to grab some datas from actions which been done from date A 00:00:00 and date B 00:00:00 (in this case
Date A: 16.07.2010
Date B: 20.07.2010)
so i wrote this select-statement:

Select avg(cnt),fext from (
        Select 
            to_char(mytable.dateadded, 'DD.MM.YYYY') dateadded,
            fext, 
            count(id) cnt 
        from mytable 
        where dateadded between
            to_date('16.07.2010', 'dd,MM,YYYY') and 
            to_date('20.07.2010', 'dd,MM,YYYY')
        group by 
            to_char(mytable.dateadded, 'DD.MM.YYYY'),
            fext)
group by fext;

The original (and working) statement had:

    to_date('16.07.2010 00:00:00', 'dd,MM,YYYY HH24:Mi:SS') and 
    to_date('20.07.2010 00:00:00', 'dd,MM,YYYY HH24:Mi:SS')

so the question is: does the

    to_date('16.07.2010', 'dd,MM,YYYY') and 
    to_date('20.07.2010', 'dd,MM,YYYY')

already set the time to date A and B to 00:00:00?

Answer 1

If you does not specify time part of date it will be 00:00:00.

If you worry about time part you always can truncate time part:

Trunc(to_date('16.07.2010', 'dd.MM.YYYY')) and 
Trunc(to_date('20.07.2010', 'dd.MM.YYYY'))
