Question

When I run this query:

SELECT * FROM tbl_person 
WHERE to_date(date_create, 'dd/mm/yyyy') < to_date('01/01/2010', 'dd/mm/yyyy')

I hit the following error:

ORA-01841: (full) year must be between -4713 and +9999, and not be 0

To be clear, date_create field stored SYSDATE when I added into table. What I need is to retrieve data from tbl_person table starting from 01/01/2010 onward.

Answer 1

You don’t want to call TO_DATE on a DATE. Just use the date column in the query (and compare it to a date)

SELECT *
  FROM tbl_person
 WHERE date_created < to_date('01/01/2010', 'dd/mm/yyyy')
