Does the DBD enclose all parameters in ''s?
Not really. It passes the parameters separately from the query.
Am I actually trying to execute:
select reserved_id, reserver, purpose, to_char(starttime, 'HH:MI'),
to_char(stoptime, 'HH:MI') from reservedroomtest where roomid in
('105, 106, 110')
To answer my own question, yes it does appear to be that way.
If I put the clause inline in the SQL (as 'in($rlist)' ) rather than as a
parameter (as 'in(?)' ), it works as expected (or at least it does when I
fix my most common datetime conversion error: MM == Months, MI==
Minutes, yah idjit Johnson!)
Is there a way to pass an unquoted list as a parameter?
No. A parameter is a parameter. You want to pass a list of parameters.
If you put it inline, you do the same:
select reserved_id, reserver, purpose, to_char(starttime, 'HH:MI'),
to_char(stoptime, 'HH:MI')
from reservedroomtest
where roomid in (105, 106, 110)

I can't do it as
'in(?,?,?,?)' etc, because the number of list elements varies from
execution to execution.
Sure you can:
$qry = select * from reservedroomtest where roomid in (
. join(,, map ?, @list)
. );
$sth = $dbh-prepare_cached($qry);
$sth-execute(@list);
