title: How to obtain data between two dates where end date is Null?
body: <p>I have a table with date created and end date column. All the elements have a date created value but not necessarily an end date value which can be null. I want to obtain rows by querying between these dates. How should I write the query such that the rows between the date created and end date are displayed along with the data whose end date is null?    </p>
