Remember, you only need to prepare a statement handle if you
are going to re-use it for more than 1 query. Otherwise, you can use
the Database Handle Methods for one-time queries. They encapsulate
a prepare, execute, and sometimes a fetch-type method in a single call. For
INSERT or UPDATE statements use DBI::do.
The following statement does a batch DELETE without
using any 'Synthetic' Code, and is tested to work with MySQL:
$dbh->do(
sprintf(
'DELETE FROM table WHERE message_id IN(%s)',
join ',', ('?') x @MESSAGE_IDS
),
{},
@MESSAGE_IDS,
);
