Purging Database - Count purged/not-purged tables

Add days, weeks, months to date using jQuery
jQuery is not for DateTime manipulation. It's for querying and manipulating DOM objects. For what you need, you can either implement that yourself, or use a specialized third-party library.

The Cognos _days_between function works with dates, not with datetimes. Some databases, like Oracle, store all dates with a timestamp.
