If you formatted your post, you'd probably get more responses.
Assuming that each of your queries produces a hashref containing the same keys, then printing the values as you've asked might look something like this:
my $hash_ref1 = $dbh->selectall_hashref( $sql1, $key_field1, {}, @valu
+es1 );
my $hash_ref2 = $dbh->selectall_hashref( $sql2, $key_field2, {}, @valu
+es2 );
my $hash_ref3 = $dbh->selectall_hashref( $sql3, $key_field3, {}, @valu
+es3 );
## for each id
for my $id ( keys %{ $hashref1 } ) {
## extract an array of results for that key from each hash
my @results1 = @{ $hashref1->{ $id } };
my @results2 = @{ $hashref2->{ $id } };
my @results3 = @{ $hashref3->{ $id } };
## join them together with spaces
## and print them along with the key
printf "%14s : %s \t%s\t%s\n", $id,
join( ' ', @results1 ),
join( ' ', @results2 ),
join( ' ', @results3 );
}
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
