Output results from a DBI select query in one line

on Apr 11, 2006 at 15:47 UTC ( #542573=snippet: print w/replies, xml ) Need Help??
Description: 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
} )};

      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);
        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.

[Corion]: Heh - I just realized, $work management just declared "no raises for anybody this year", and I'm not even angry about that. Even though that implicitly means "raises for the people with an automatic 5% raise in their contract", which the newly-merged ...
[Corion]: ... coworkers have. But I guess I've gone more mellow since I get to relax more, and such stuff doesn't make me as angry as it used to.
[Corion]: $boss will still get to listen to my interpretation :-D
[Eily]: hey, I'm just behind Larry in SioB \o/
[Corion]: Eily: Wheee ;)
[Eily]: I'll add that to my résumé
