Use the "IN" operator instead of "OR". Here's my favorite idiom (using placeholders):

my @ids_to_match = ( ... );
my $query = "SELECT somedata from table WHERE id IN ("
    . join(",", map {"?"} @ids_to_match )
    .")";

my $sth = $dbh->prepare($query);

$sth->execute(@ids_to_match);

Alternatively:

my $query = "SELECT somedata from table WHERE id IN ("
    . join(",", map { $dbh->quote($_) } @ids_to_match )
    .")";

my $sth = $dbh->prepare($query);

$sth->execute();
