Answer 1

You can also change the date format for the session. This is useful, for example, in Perl DBI, where the to_date() function is not available:

ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD'

You can permanently set the default nls_date_format as well:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD'

In Perl DBI you can run these commands with the do() method:

$db->do("ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD');

Answer 2

try to save date like this yyyy-mm-dd hh:mm:ss.ms for example: 1992-07-01 00:00:00.0 that worked for me

Answer 3

The format you use for the date doesn't match to Oracle's default date format.

A default installation of Oracle Database sets the DEFAULT DATE FORMAT to dd-MMM-yyyy.

Either use the function TO_DATE(dateStr, formatStr) or simply use dd-MMM-yyyy date format model.

Answer 4

If you provide proper date format it should work please recheck once if you have given correct date format in insert values

Answer 5

Try the format as dd-mon-yyyy, For example 02-08-2016 should be in the format '08-feb-2016'.

Answer 6

Try replacing the string literal for date '1989-12-09' with TO_DATE('1989-12-09','YYYY-MM-DD')
