Re: Problem : Doing case-insensitive queries...

How about writing a function to be used with your where clause in the select statement?
select name from MyTab where name = MyFunc(name,'bill');

create or replace function MyFunc(name varchar2, myparam varchar2) return varchar2 is
begin
  if lower(name) = lower(myparam) then
    return(name);
  else
   return(myparam);
 end if;
end;
