I think DBI already does what you want, from the docs:

You may often want to fetch an array of rows where each row
is stored as a hash. That can be done simple using:

my $emps = $dbh->selectall_arrayref(
"SELECT ename FROM emp ORDER BY ename",
{ Slice => {} }
);

It's then an array rather than a hash, but that's better, right?

Have a nice day,
