in thread array references in DBI

Thank you for pointing this out. What if @an was lexical but declared before the while loop? I would have the same problem, no?

    Yes, you would be pushing the same array ref every time, and the contents would change afterwards.

    Test code (no DBI involved):

    my @rows; my @row = qw(one two); push @rows, \@row; @row = qw(three four); use Data::Dumper; print Dumper \@rows; __END__ $VAR1 = [ [ 'three', 'four' ] ];

    As you can see, the contents of the collating array changes after you put it in there.
