Freezer has asked for the wisdom of the Perl Monks concerning the following question:

Hello there,

Please could anyone advise me why my array is something like:

ARRAY(0x943548)ARRAY(0x943548)ARRAY(0x943548)ARRAY(0x943548)
The code that produces this is like:
while(@row_B = $sth_B->fetchrow_array()) { @record_B = @row_B; push(@fields_B, \@record_B); } $sth_B->finish();

    To expand on what moritz said, you also don't need to copy @row_B to @record_B before taking a reference. I believe fecthrow_arrayref re-uses the same ref, which requires you to copy the data, but fetchrow_array is returning you the list, so if you use my as moritz said, the ref will change each time you pull a record, simplifying.

    Of course, if all you want is an array of arrays of the data, look at fetchall_arrayref in the DBI documentation
