I am not sure about the data, but when we do SELECT count(*) from data_realtime where dt='20120730' and uid is null
I get the count but If I do- SELECT * from data_realtime where dt='20120730' and uid is null I get zero record back. But if all the record is NULL then I should be getting NULL record back right? But I am not getting anything back and that is the reason it is making me more confuse.
