TO_DATE function in ORACLE

Question

I was trying the TO_DATE function. Specifically, I noted that the following queries

1. SELECT TO_CHAR(TO_DATE(\'01-01-2015\',\'DD-MM-YYYY\'),\'DD-MO         


        

Answer 1

Oracle TO_DATE: is used to convert a character string to a date format.

and related to your concern; you need to alter your session like below:

alter session set nls_date_format='DD-MM-YYYY'

in your apps right after the connect.

So now if you run again your query :

SELECT TO_DATE ('01-01-2015', 'DD-MM-YYYY')
FROM DUAL;

the result would be as expected:

01-01-2015

Hope that will help.
