using reference to the fetched rows

[Manish Sapariya]

Hi list,
When using DBI module as,

my $return_list = $sth->fetchrow_arrayref;

Can I copy the reference to some other variable

say, e.g.

my $CopyOfResult = $return_list;

and do another query using the same handle and
use $CopyOfResult and $return_list?

My question is how does perl will release the
memory used to store the results?

Thanks,
Manish
