in thread multidimensional array's

@All: Thnx a lot for your helpful answers.

With some additional reading and fiddling around with the syntax I have figured this out now.

my @allrows =(); while ($row = $sth->fetchrow_arrayref() ) { push @allrows,[@$row]; }; my $titlesfound = @allrows; # Contains the number of results #Show that it works: $loopcount = 0; foreach (@allrows) { my $title1 = ($allrows[$loopcount][1]); print "$title1\n"; $loopcount++; };

/emgi

    If you do not need the @allrows array, it is wasteful to store data into it. Try this instead:
    my $loopcount = 0; while (my $row = $sth->fetchrow_arrayref() ) { my $title1 = $row->[1]; print "$title1\n"; $loopcount++; }; my $titlesfound = $loopcount;
