Gilles Rayrat resolved CAROB-47:
--------------------------------
Resolution: Fixed
Fix Version: V1.0 - full version

> When executing the above specified commands, an exception is thrown:
> terminate called after throwing an instance of 'std::logic_error'
> what(): basic_string::_S_construct NULL not valid
> The code fragment where this happening:
> wstring DriverResultSet::getString(int32_t columnIndex) throw (SQLException,
> UnexpectedException)
> {
> checkRowAndColPosAndSetNullFlag(columnIndex);
> if (wasNullFlag)
> return NULL; <---- exception is thrown here
> wstring can't be initialized with NULL.
> Needs another logic for this function to signal NULL values.
