Re^3: Selecting DB

Yes. The next problem is:

    my $rez = join( ",", $em);
[download]

Most likely you wanted:

    my $rez = join( ",", @$em);
[download]

Maybe you want to read tye's References Quick Reference, and/or use Data::Dumper a lot?

If you want all the emails comma (and possibly comma + newline) separated, avoid the foreach loop, and simply concatenate the results: `my $rez = join(",\n", @$user1, @$user2); # Remove the \n if you want + just CSV` [download] "These opinions are my own, though for a small fee they be yours too."
