in thread DB search results using DBI...execute

yes! ty for that. not entirely certain how that helps...perhaps i'm misguided. i'm asking why the code gives back a 3...not if search_item() is more relevant than sql_execute(). frankly, your reply, although highly appreciated, makes little sense to me.

    my @results = search_item($dbh, \@users, $st, $sv) . "\n"; is slightly incorrect, btw - and not sure how the "\n" got in's not there in my actual code. so, it should read just: my @results = search_item($dbh, \@users, $st, $sv);

      Try this simple cgi to show the benefit of using Dumper.

      #!perl # Dumper demo cgi use strict; use Data::Dumper; print "Content-Type: text/html\n\n"; print '<pre>'; my $ref = [ { ID => 'ABC'},{ ID => 'DEF'},{ ID => 'GHI'} ]; print '<h2>$ref</h2>'; print Dumper $ref; print '<hr/>'; my @array = map { $_->{ID} } @$ref; print '<h2>@array</h2>'; print Dumper @array; print '<hr/>'; my @error = @array."\n"; print '<h2>@error</h2>'; print Dumper @error; print '<hr/>';

      Also, note how map could be used to replace this code in search_item()

      my @array = @$resultsRef foreach my $hit (@array) { # $hit is a hash reference. my %hash = %$hit; push @searched, $hash{ID}; }
        even better though, would be to drop the %hash = %$hit and write the push command as push(@searched, $hash->{ID}); which saves so much typing, and is much more readable and understandable...having to do "my %hit = ..." gets tedious - especially when yer imagination for new var names gets exhausted lol
        haha! yes, yes - quite correct. it's been a long while since I looked at this thread, and I am so very happy that I changed this search_item to reflect how you wrote it. I recoded that routine long ago - so that makes me feel great and feel like i'm on the right track with that, so thank you very much! most cool
