Question

I have a table with data since 2012. I need to get data in this table from 31 days back from given date. so i wrote below query to get data.

select ('[' || work_date || '] ' || field_name || ' - ' ||work_desc) d
from DAILY_WORK
where TO_CHAR(work_date,'DD/MM/YYYY') >= TO_CHAR(to_date('30-Jan-13','dd-MON-yyyy') - (31),'DD/MM/YYYY')
order by work_date desc

When i execute this query, it returns data in below dates only.

31-AUG-12
31-OCT-12
30-DEC-12
31-DEC-12

But actually i need to get data from 2012-12-30 to 2013-01-30.

How could i do this ?

Answer 1

use this:

select ('[' || to_char(work_date, 'dd-MON-yyyy') || '] ' || field_name || ' - ' ||work_desc) d
from DAILY_WORK
where work_date >= to_date('30-Jan-2013','dd-MON-yyyy') - 31
order by work_date desc
