Well that depends. If you can somehow flag which fields have valid values
(perhaps by adding another flag field and using the column flags), you could
simply proceed and wait to see if the actual data is needed.

In generaly, you probably shouldn't lie to the client.

These are pretty much equivalent.. once you return an error, the data
won't/shouldn't get back to the client...
