I had trouble getting my head around the "OPENQUERY-1" question a few days back, but found this question a little easier thanks to the research and discussion of that one.

... I notice, though, that similar to the first "OPENQUERY" QOD question, the answer '-1' gets 3% of the total answers for this QOD.

What I'm having trouble getting my head around now is - has anyone figured out what a return of -1 rows is going to look like? 😛
