SQL::NamedPlaceholder - extension of placeholder
use SQL::NamedPlaceholder qw(bind_named);
my ($sql, $bind) = bind_named(q[
SELECT *
FROM entry
WHERE
user_id = :user_id
], {
user_id => $user_id
});
$dbh->prepare_cached($sql)->execute(@$bind);
SQL::NamedPlaceholder is extension of placeholder. This enable more readable and robust code.
-
($sql, $bind) = bind_named($sql, $hash);
The $sql parameter is SQL string which contains named placeholders. The $hash parameter is map of bind parameters.
The returned $sql is new SQL string which contains normal placeholders ('?'), and $bind is array reference of bind parameters.
-
:foobar
Replace as placeholder which uses value from $hash->{foobar}.
-
foobar = ?, foobar > ?, foobar < ?, foobar <> ?, etc.
This is same as 'foobar = :foobar'.
