Yii2.0单个与批量删除数据

直接 model 删除

$model = User::find($id); $model->delete();

带有条件的删除

$connection ->createCommand()
            ->delete('tbl_user', 'status = 0')
            ->execute();

使用 Query 查询删除

$connection ->createCommand('DELETE FROM tbl_user WHERE userid=:userid')
            ->execute();

使用预处理语句删除

$model = $connection->createCommand('DELETE FROM tbl_user WHERE userid=:userid'); $model->bindParam(':userid', $userid); $userid = 5; $model->execute();

$model = $connection->createCommand('DELETE FROM tbl_user WHERE userid=:userid'); $model->bindParam(':userid', $userid);
// delete user 1 $userid = 1; $model->execute();
// delete user 2 $userid = 2; $model->execute();

查找并且删除

$user = User::findOne(2); $user->delete();
// 输出语句
// DELETE FROM `tbl_user` WHERE `id`='2'

deleteAll() 删除多个

User::deleteAll('status = :status AND age > :age', [':age' => 20, ':status' => 'active']); //Output Query //DELETE FROM `tbl_user` WHERE status = 'active' AND age > 20

User::deleteAll([ 'and', 'type = :type_id',
        ['not in', 'usercategoryid', $categoriesList]
    ],
    [ ':type_id' => 2
    ]); //Output Query //DELETE FROM `tbl_user` WHERE (type = 2) AND (`usercategoryid` NOT IN (1, 2, 3))
