Yitzchak,

I cannot thank you enough for your suggestion. Yes, fetchall_arrayref( {} )
worked perfectly. I still do not have a good understanding as to when to
use fetchall_hashref and when to opt for fecthall_arrayref() instead. I
really really appreicate your help in getting me straightened out.

Thank you again.
