I want to load the results of 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.
######### load the query results into an AoAref's ###################
my @qrydata; # I want to load the query rows into this array.
my $xx=0; #row counter
while (my $row = $sth->fetchrow_arrayref) {
# See if the arrayref has the expected data - it does.
for my $fld(@$row) { print "$fld|"; } print "\n";
# so push the arrayref onto the AoAref's
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.
