Question

is there a way to batch up deletes for MySQL when using PHP (mysqli)?

With inserts you can do something like

insert into tbl (...) values (...) (...) (...) ...

is there any equivalent for deletes?

Answer 1

delete from tbl where id IN (1,2,3)

OR

delete from tbl where id = 1 OR id = 2 OR email = '[e-mail]'

you can make sure you delete the right data by doing select first…

ps: for the php,

<?
$ids = array(1,2,3);

$sql = "DELETE FROM tbl WHERE id IN (" . implode(',', $ids) . ")";
?>

or

<?
$deleteme = array("id = 1", "id = 2", "email = '[e-mail]'");

$sql = "DELETE FROM tbl WHERE " . implode(' OR ', $deleteme);
?>
