my @intervals = $poller_db->resultset('Aggregation')->
search({aggregation_interval => undef,})

In my Database, there are many tables of which 'aggregation' is one of them. In this table, there is a column named 'aggregation_interval'. I am using MySQL. Now I have the following questions: 1. What value is stored in @intervals 2. How is it possible to have 'Aggregation' in code and 'aggregation' table in database 3. What does 'undef' signify here.
