I encountered the same problem and compiled a version of mxODBC.dll
that does not throw an error if a type is unknown. Instead it tries to
return a string representation of the value by default.
So the problem starts at line 2039 of mxODBC.cpp that comes with the
package. I added the default behaviour there.
