"Not a Valid Month" Error

Error received when trying to insert a date into a date field:

INSERT INTO TableName(Field1)VALUES('01/22/2013');

Cause: The date format specified in an INSERT statement dow not match NLS_DATE_FORMAT parameter.
To check NLS_DATE_FORMAT parameter, run:

SELECT sysdate FROM dual;

The output should be something like this: 22-JAN-13
Solution: Modify SQL statement to read:

INSERT INTO TableName(Field1)VALUES(to_date('22-JAN-2013'));
