Your way of doing it seems perfectly fine. The typical way
to do selects with DBI is:
The fetch is typically done in a loop (either in the program,
or by the DBI), and you can have multiple execute/fetch cycles
for a prepare (another advantage of placeholders).
Since the second query doesn't depend on the results of the
first, doing all the actions of the first before starting
with the second is fine.
No doubt I would write it differently than you, but in essence, it would still do the same, in the same order.
