If the column used in the where clause is indexed, which one of the following is more ideal so it uses the index optimally:

1. WHERE Status != 0

EXPLAIN RESULTS:
select_type: SIMPLE
type: range
possible_keys: PRIMARY
key: PRIMARY
key_len: 1
ref: null
rows: 3
Extra: Using where


2. WHERE Status > 0

EXPLAIN RESULTS:
The only difference from the above results is:
rows: 2

but I do not know what rows stand for.

Thanks,
