ResultSet checks if the column number of data matches the one in metadata by calling iterator.next() to get a sample row, which would make the first row missing in the final result.
The bug didn't appear in the tests, because the condition is wrong. Fixed by c0e9072a4c3383562b0fe1938e3bfa1947376754.
