Output results from a DBI select query in one line

I'm finding myself using this idiom a lot for a current project. Adjust to taste for your own applications.

# given a DBI handle $dbh, a database table "foo" with a column "bar"

print join "\n", map join("\t", @$_), @{$dbh->selectall_arrayref( q{
   select bar from foo
} )};

Why not just: `$_->execute(4, 5), $_->dump_results for $dbh->prepare(q{ SELECT one, two FROM three WHERE four = ? AND five = ? });` [download] -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply] [d/l]

Or, a couple of characters shorter than that (if we don't count loading Dumper): `print Dumper $dbh->selectall_arrayref("SELECT one, two FROM three WHER +E four=? AND five=?",{},4,5);` [download]	[reply] [d/l]

Either merlyn's or jZed's examples are fine for diagnostics. The original, however: won't truncate values as `dump_results` does provides more human-readable output than Data::Dumper's structures But feel free to use whatever works for you. Mine was just more appropriate for my project.	[reply] [d/l]
