Question

I need at some point to increment dynamically a timestamp plsql variable.
So, instead of doing this:

timestamp_ := timestamp_ + INTERVAL '1' DAY;

I would like to do thomething like this:

timestamp_ := timestamp_ + INTERVAL days_ DAY;

It doesn’t really work.
My final goal is to dynamically create some scheduler jobs for some entities that have an variable expiration date, to avoid creating a single one which would be often executed.

Answer 1

It sounds like you want

timestamp_ := timestamp + numtodsinterval( days_, 'day' );

I would be somewhat cautious, however, about an architecture that involves creating thousands of scheduler jobs rather than one job that runs periodically to clear out expired rows. A single job is a heck of a lot easier to manage and oversee.
