批量删除和批量更新

Question

http://www.yiiframework.com/doc-2.0/yii-db-command.html#delete()-detail

I see in the documentation a batch insert, but no batch delete or batch update. Is there a way to implement a batch update and delete using Yii's db API? What's the best way? I want to avoid using a loop and making several requests. Also, I am using Yii 1.0. I noticed there's no doc for 1.0, will those methods work in 1.0?

If you want to delete or update few rows you should use WHERE. No one make batch delete like this DELETE ... WHERE id=1; DELETE ... WHERE id=2; DELETE ... WHERE id=1; DELETE ... WHERE id=2; you can do it like this DELETE ... WHERE id IN(1,2);

Batch insert for Yii 1 is available only since 1.1.14.

$builder=Yii::app()->db->schema->commandBuilder;
$command=$builder->createMultipleInsertCommand('tbl_post', array( array('title' => 'record 1', 'text' => 'text1'), array('title' => 'record 2', 'text' => 'text2'), ));
$command->execute();

This is the doc for 1.0
