In the select statement for several reports I've noticed these fields:

changetime AS _changetime
description AS _description

What does this actually do? These fields do not show up anywhere in the report as far as I can tell. I gather the leading underscore makes this some kind of special field. But, where does it come into play? In the report that has "Full Description", the description field instead has a trailing underscore as well. This appears to put the description onto its own line. That makes sense. But, with the others, is there are any purpose or is it just wasting query time?

Thanks,
