Question

I have this query which is not returning any rows. But there are records which are greater than 25-JUN-90 date. Why is it not working?

{SELECT employee_id, last_name,hire_date
   FROM employees WHERE hire_date > TO_DATE('25-JUN-90','dd-mon-yy');}

Answer 1

You want to use the RR date format mask to change 90 to 1990:

SELECT employee_id, last_name,hire_date
FROM employees WHERE hire_date > TO_DATE('25-JUN-90','dd-mon-RR');
