Easiest way would be

select * 
  from Sample 
  where (name = 'ab' and `key` = '12') 
    or (name = 'fb' and `key` = '13')

Demo here: http://sqlfiddle.com/#!9/3eabc/3

Throw an index on (name, key) for good measure.

create index name_key on sample(name, `key`);

Easiest way would be union all

select * from Sample where name ='ab' and key= '12' 
union all
select * from Sample where name ='fb' and key= '13'
