Query not getting current date result - sql

Question

I am getting data from table for certain date range, but the query not getting data for today's date. Why does this happen?
select *
from mytable
where action_date >= to_date('01/07/2015', 'DD/MM/YYYY')
and action_date <= to_date('22/07/2015', 'DD/MM/YYYY');
Result is not showing 22/07/2015 data.
Edit:
ACTION_DATE TIMESTAMP(6)
Sample date in that column :
22/07/15 12:47:18.000000000 PM

Answer 1

Try to add the time part:
select *
from mytable
where action_date >= to_date('01/07/2015 00:00:00,000000000', 'DD/MM/YYYY HH24:MI:SS,FF9')
and action_date <= to_date('22/07/2015 23:59:00,999999999', 'DD/MM/YYYY HH24:MI:SS,FF9');
If you only give the date part, the time part is automatically added with the actual time, so if the time part is later you do not get the row.

Answer 2

to_date('22/07/2015', 'DD/MM/YYYY')
this will equal to July, 22 2015 00:00:00
From Oracle document:
Oracle Database stores time in 24-hour format—HH:MI:SS. By default,
the time in a date field is 00:00:00 A.M. (midnight) if no time
portion is entered.
so action_date <=/>= will compare the data+time.
For the correct result add required time to the date field.
eg:
to_date('22/07/2015 12:56', 'DD/MM/YYYY HH24:MI')

Answer 3

it is because you are converting to_date in date, that results in 22/2/2015 00:00:00 and your action_date time for 22/7/2015 is with some time appended. you need to convert action_date in date.
select * from mytable where cast( action_date >= to_date('01/07/2015', 'DD/MM/YYYY') and cast( action_date as date) <= to_date('22/07/2015', 'DD/MM/YYYY');

Answer 4

I have changed the query by this way, its working as expected.
SELECT *
FROM mytable
WHERE action_date >= to_date('01/07/2015', 'DD/MM/YYYY')
AND TRUNC(to_date(TO_CHAR(action_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) <= TRUNC(to_date('22/07/2015', 'DD/MM/YYYY'));

Answer 5

You can use the below query.
select *
from mytable
where trunc(action_date) >= to_date('01/07/2015', 'DD/MM/YYYY')
and trunc(action_date) <= to_date('22/07/2015', 'DD/MM/YYYY');
This will perform a date-level comparison rather than one based on the date and exact time.

Answer 6

This is better than the (original) accepted answer, which misses a small period of time after 23:59.
select *
from mytable
where action_date >= to_date('01/07/2015', 'DD/MM/YYYY')
and action_date < to_date('22/07/2015', 'DD/MM/YYYY') + 1;
Or alternatively if you don't like the +1:
select *
from mytable
where action_date >= to_date('01/07/2015', 'DD/MM/YYYY')
and action_date < to_date('23/07/2015', 'DD/MM/YYYY');

Answer 7

The easiest solution is to use '< nextday' instead of boring '<= 23:59:59'.
select * from mytable
where action_date >= to_date('01/07/2015', 'DD/MM/YYYY')
and action_date < to_date('23/07/2015', 'DD/MM/YYYY');
