[odb-users] Small documentation error

[Dieter Govaerts]

Hello,

I've found a small error in "7.3 Pointers and NULL Value Semantics" in the sample code for the nullable interface:

  // The same using the pointer interface.
  //
  if (ns)
  {
  // ...

should be (condition negation):

  // The same using the pointer interface.
  //
  if (!ns)
  {
  // ...

Regards,
Dieter
