如何在Yii2中插入批量数据库? [英] How to do a bulk database insert in Yii2?

问题描述

我想知道您如何在Yii2中创建批量数据库INSERT?

I'm wondering how you go about doing a bulk database INSERT in Yii2?

例如，普通的INSERT我想这样:

For example a normal INSERT I would like so:

$sql = $this->db("INSERT INTO some_table(id,my_value) VALUES(:id,:my_value)");
$sql->bindValues([':id' => $id, ':my_value' => $my_value]);
$sql->execute();

现在，如果我要创建批量INSERT，怎么办?

Now what if I wanted to create a bulk INSERT?

没有绑定值，您可能会这样:

Without binding values you could it something like:

foreach ($foo as $bar) {
    $data_sql .= '(' . $id . ',' "'" . $bar . "'),"
}

$data_sql = rtrim($data_sql, ',');

$sql = $this->db("INSERT INTO some_table(id,my_value) VALUES" . $data_sql);
$sql->execute();

但是，如果仍然要绑定值，如何实现呢?

But how can you achieve this if you still want to bind the values?

编辑:该问题与链接的问题不同，因为我没有使用ActiveRecord.

This question is not the same as the linked one as I am not using ActiveRecord.

理想情况下，如果有一种解决方案可以提供一定的灵活性，例如能够编写大多数自己的语法，作为下面发布的答案之一，那将是一件好事:

Ideally it would be good if there was a solution that offered some flexibility, such as being able to write most of your own syntax, as one of the answers posted below:

Yii::$app->db->createCommand()->batchInsert('tableName', ['id', 'title', 'created_at'], [
    [1, 'title1', '2015-04-10'],
    [2, 'title2', '2015-04-11'],
    [3, 'title3', '2015-04-12'],
])->execute();

...不提供.对于这种特殊情况，我需要使用上述解决方案不提供的IGNORE语句.

...doesn't offer that. For this particular situation I need to use the IGNORE statement, which the above solution doesn't offer.

推荐答案

有一个特殊的batchInsert方法:

There is a special batchInsert method for that:

Yii::$app->db->createCommand()->batchInsert('tableName', ['id', 'title', 'created_at'], [
    [1, 'title1', '2015-04-10'],
    [2, 'title2', '2015-04-11'],
    [3, 'title3', '2015-04-12'],
])->execute();
