->limit()

Описание

Sets the limit for a query. (this only works on databases that support the LIMIT clause), without parameters, it will clear the current limit.

Параметр

• int $from - limit start (or number), or blank to reset

• int $number - limit results to number

Заметка

Эта функция не должна вызываться статически.

Since postgres and mysql only really support limit directly - calling this on an unsupported database will emit a PEAR::Error and die.

Пример

$person = new DataObjects_Person;
$person->limit(2);
$person->find();
while ($person->fetch()) {
    echo "{$person->id} {$person->name}<BR>";
}


$person = new DataObjects_Person;
$person->limit(2,4);
$person->find();

while ($person->fetch()) {
    echo "{$person->id} {$person->name}<BR>";
}

SELECT * FROM person LIMIT 2

SELECT * FROM person LIMIT 2,4
