PHP 클래스 yii\db\BatchQueryResult

You usually do not instantiate BatchQueryResult directly. Instead, you obtain it by calling [[Query::batch()]] or [[Query::each()]]. Because BatchQueryResult implements the [[\Iterator]] interface, you can iterate it to obtain a batch of data in each iteration. For example, php $query = (new Query)->from('user'); foreach ($query->batch() as $i => $users) { $users represents the rows in the $i-th batch } foreach ($query->each() as $user) { }

공개 프로퍼티들

프로퍼티 타입 설명
$batchSize the number of rows to be returned in each batch.
$db the DB connection to be used when performing batch query. If null, the "db" application component will be used.
$each whether to return a single row during each iteration. If false, a whole batch of rows will be returned in each iteration.
$query the query object associated with this batch query. Do not modify this property directly unless after BatchQueryResult::reset is called explicitly.
