Описание

Executes a SQL query, but fetches only the the specificed count of rows. It is an emulation of the MySQL LIMIT option.

Параметр

Возвращаемое значение

mixed - a new DB_result object for queries that return results (such as SELECT queries), DB_OK for queries that manipulate data (such as INSERT queries) or a DB_Error object on failure

Throws

Заметка

Эта функция не должна вызываться статически.

Depending on the database you will not really get more speed compared to query(). The advantage of limitQuery() is the deleting of unneeded rows in the resultset, as early as possible. So this can decrease memory usage.

Also note that $from and $count are not being escaped. You should take care of sanitizing input yourself, or you are open to an SQL injection attack.

Пример

<?php
// Once you have a valid DB object named $db...
$res =& $db->limitQuery('SELECT * FROM foo', 49, 10);

if (PEAR::isError($res)) {
    die($res->getMessage());
}
?>
