It is certainly possible and is a trivial requirement. All you're doing is a filtering here, across multiple columns (OR-wise). Perhaps something like (Pardon if naive/wrong): "SELECT * FROM people WHERE residence_place LIKE '%New York%' OR work_place LIKE '%New York%';" In any case, for Hive questions, you are better off asking the u...@hive.apache.org lists than the Hadoop user lists here. -- Harsh J
