Implementing insertFromSelect in Magento 2
To insert data into a Magento 2 database using the insertFromSelect() method, follow these steps:
Set Up the Class:
Begin by declaring strict types and defining your namespace. Import the necessary Magento classes:
Here's a concise PHP code example demonstrating this process:
<?php
declare(strict_types=1);
namespace Vendor\Module\Index;
use Magento\Framework\App\ResourceConnection;
use Magento\Framework\DB\Adapter\AdapterInterface;
Define the Class and Constructor:
Create the InsertFromSelect class and inject the ResourceConnection dependency:
class InsertFromSelect
}
private const CATALOG_PRODUCT_ENTITY_VARCHAR = 'catalog_product_entity_varchar';
public function __construct(
private readonly ResourceConnection $resourceConnection
) {
}
}
Execute the Insert from Select:
Within the execute method, establish a database connection, define table names, and set attribute IDs:
public function execute()
}
$connection = $this->resourceConnection->getConnection();
$catalogVarcharTable = $connection->getTableName(self::CATALOG_PRODUCT_ENTITY_VARCHAR);
$smallImageAttributeId = 88;
$imageAttributeId = 87;
}
Construct the Select Query:
Build a select query to retrieve data for insertion:
$select = $connection->select()
->from(
$catalogVarcharTable,
[new \Zend_Db_Expr($imageAttributeId), 'store_id', 'value', 'row_id']
)
->where("value != 'no_selection'")
->where('attribute_id = ?', $smallImageAttributeId);
Perform the Insert Operation:
Use the insertFromSelect method to insert data, specifying the desired behavior with the fourth parameter:
$insertFromSelectQuery = $connection->insertFromSelect(
$select,
$catalogVarcharTable,
['attribute_id', 'store_id', 'value', 'row_id'],
AdapterInterface::INSERT_IGNORE
);
$connection->query($insertFromSelectQuery);
By following these steps, you can effectively use the insertFromSelect() method in Magento 2 to insert data into your database while adhering to best practices.
