Your description is very vague.  What do the result sets look like?  Are they file?  Are they arrays or hashes?  What type of output are you looking for?

The general approach is to use a hash with a unique key.  Something like the following (which assumes that the data is in two hashes where the key is the id and the value is the data).
foreach (keys %ResultSet1)
{
 push @{$FinalResult{$_}}, $ResultSet1{$_};
}
foreach (keys %ResultSet2)
{
 push @{$FinalResult{$_}}, $ResultSet2{$_};
}
foreach (keys %FinalResult)
{
 print join(" \n", $_, @{$FinalResult{$_}}), "\n";
}
