yii批量数据插入

yii框架批量插入数据有两种方法，第一种是循环多次插入和一次批量插入，第一种方法要注意插入数据中间有一次数据插入失败要注意回滚事务

循环插入数据

第一种方法

$model = new User();
$transaction=Yii::app()->db->beginTransaction();
try{
    foreach($data as $attributes)
    {
        $_model = clone $model; //克隆对象
        $_model->setAttributes($attributes);
        $_model->save();
    }
    $transaction->commit();
} catch(Exception $e){
    $transaction->rollBack();
}

第二种方法

$model = new User();
$transaction=Yii::app()->db->beginTransaction();
try{
    foreach($data as $attributes)
    {
        $model->isNewRecord = true;
        $model->setAttributes($attributes);
        $model->save() && $model->id=0;
    }
    $transaction->commit();
} catch(Exception $e){
    $transaction->rollBack();
}

批量插入数据

生成SQL：INSERT INTO users (id, name) VALUES (:id0, :name0),(:id1, :name1)

绑定参数：array(2) {[":id0"]=>int(1)，[":name0"]=>string(4) "John"}

/**

 */
function insertSeveral($table, $array_columns)
{
    $sql = '';
    $params = array();
    $i = 0;
    foreach ($array_columns as $columns) {
        $names = array();
        $placeholders = array();
        foreach ($columns as $name => $value) {
            if (!$i) {
                $names[] = $this->_connection->quoteColumnName($name);
            }
            if ($value instanceof CDbExpression) {
                $placeholders[] = $value->expression;
                foreach ($value->params as $n => $v)
                    $params[$n] = $v;
            } else {
                $placeholders[] = ':' . $name . $i;
                $params[':' . $name . $i] = $value;
            }
        }
        if (!$i) {
            $sql = 'INSERT INTO ' . $this->_connection->quoteTableName($table)
                . ' (' . implode(', ', $names) . ') VALUES ('
                . implode(', ', $placeholders) . ')';
        } else {
            $sql .= ',(' . implode(', ', $placeholders) . ')';
        }
        $i++;
    }
    return $this->setText($sql)->execute($params);
}
$rows = array(
    array('id' => 1, 'name' => 'John'),
    array('id' => 2, 'name' => 'Mark')
);
echo insertSeveral('users', $rows);
