<p>I'm fully aware that set division can be accomplished through a series of other operations, so my question is:  </p>

<p>Is there a command for set division in SQL?</p>

From Page 32:
Relational Division is not a fundamental operator. It can be expressed in terms of projection, Cartesian product, and set difference.
So, no. :)
