Thanks for your help everyone!

It turns out that the issue I was having had to do with the version of the FreeTDS driver I was using. The version I was using, 0.61, had an issue with NULL bindings that has since been fixed in versions 0.61.1 and newer.

My systems administrator has upgraded our driver to version .82 and I am now able to insert NULL values.
