in reply to Re^2: fastest method to use DBI
in thread fastest method to use DBI

I suspect what the OP saw was something about fetchall_arrayref bering the fastest way to fetch all the data, which is true since it doesn't require looping in perl. However, fetchall_arrayref doesn't work with bind_columns. Also, since the OP is only after a single row, there is no advantage to fetchall_arrayref.
