Dear Monks, Using DBI with MySQL, I want to load the results of SELECT via fetchrow_arrayref into an array of arrayrefs. I'm doing something wrong because I end up with a thousand copies of the last row retrieved instead of a thousand unique rows. 

my @qrydata; # I want to load the query rows into this array.

my $xx=0; #row counter
while (my $row = $sth->fetchrow_arrayref) {
  # Does the arrayref have the expected data? Yes - unique rows
    for my $fld(@$row) { print "$fld|"; } print "\n";
  # so push the arrayref onto the Array
    push @qrydata, $row;
  # cut it short for test purposes - save 10 rows
    last if $xx++ >10;   
}
# this prints out 10 copies of the last row fetched!! :(
for my $row (@qrydata) {
    for my $fld(@$row) { print "$fld<"; } print "\n";
}

Any insights would be appreciated. Why am I doing this? I need the total row count before I proceed. I'm thinking this is faster than running SELECT COUNT first for the query, then iterating through the query again. At this point I'm rethinking this, but still want to know what's wrong with my array scheme.
