Keep in mind, though, that the ODBC driver is not linked to your app.
It is only loaded on demand at run time, and can be replaced by any
other ODBC driver.   So AFAIU your application is "shielded" from GPL.
IANAL of course.  Saith the GPL:

  These requirements apply to the modified work as a whole.  If
  identifiable sections of that work are not derived from the Program,
  and can be reasonably considered independent and separate works in
  themselves, then this License, and its terms, do not apply to those
  sections when you distribute them as separate works.
  [...]
  In addition, mere aggregation of another work not based on the Program
  with the Program (or with a work based on the Program) on a volume of
  a storage or distribution medium does not bring the other work under
  the scope of this License.
