No, if you use a templating system like Django's then basically you pass
a QuerySet to your template.  A QuerySet is basically a pointer to a SQL
query, for example.  The templating system just knows to expect an
iterable, it can be a list of rows or it can be a QuerySet which does a
fetch from a database.  No need to shove an entire table into a
variable.

Another advantage if templates for many is that it allows programmers to
do what they do best (write code) while letting web designers do what
they do best (designing web pages) without them walking over each other
(that much).
