Try
select min(name) as Name, master_code ;
  from company ;
  where Master_Ind = 'Y' ;
  OR NOT EXISTS ;
(select 1 from Company Co where Co.Master_Code = Company.Master_Code and Co.Master_Ind = 'Y') ;
  group by master_code ;
  order by name, master_ind desc
If it's not broken, fix it until it is.
