Question

I have a function that returns a date (actual a timestamp, date+time).
In the table it looks like this, “2010-09-05 17:33:00”.
when i call my function from an sql script like,

select my_package.my_function('2010-09-05') 
  from dual.

I’ll get time in the result.

But if I run the same in a test window I’ll only receive the date and not the time.

How could this be?

Answer 1

you are seeing the effect of the NLS_DATE_FORMAT setting. set that as required. eg:

alter session set NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss";
select my_package.my_function('2010-09-05') from dual;

to see the output properly.

or TO_CHAR the output.

select to_char(my_package.my_function('2010-09-05'), 'yyyy-mm-dd hh24:mi:ss') from dual;
