in reply to fetchall( )

But i want to save the data all in a array or something. Because i need to compare it with itself. So i need all the data to be safed. So i can acces it later on. Like a 2d array

    When you do a fetchall_arrayref, that returns a reference to what is essentially a 2d array.
    my $ref = $sth->fetchall_arrayref(); gives: $ref [ [row of 1st data in here], [2nd row data here], [3rd row of data here] ]
      than i would have something like this: row1: name, adress, place row2: name, adress, place row3: name, adress, place And how do i select by example only the name of row 2?
        with something like this:
        my $ref = $sth->fetchall_arrayref(); my $second_name = $ref->[1]->[1];
        To iterate over all the results and print them, you could do:
        my $ref = $sth->fetchall_arrayref(); foreach my $inner (@$ref){ print join ("\t", @$inner), "\n"; }
        -albert
