> ...IN would operate on a given row, and return True when the first argument equaled at
least one of the other arguments. So here IN would return true if 12345=key1 OR 12345=key2
OR 12345=key3 (but wouldn't test the latter two if the first matched).
> This would also help with https://issues.apache.org/jira/browse/HIVE-783, if IN were
implemented in a manner that allows it to be used in an ON clause.
