Well, it depends alot on what datatype your form and url variables are that you're using in the sql statements.  if they're all numbers, then simply wrapping their use in the sql statements with the Val() function should take care of the problem for ya.  so, instead of this:

  FROM bar
 WHERE id = #url.bar_id#

change it to this:

  FROM bar
 WHERE id = #Val(url.bar_id)#

now, if you're using strings in some of your statements then you need to take a look at the <cfqueryparam> tag.

good luck,
