Add record using insert query in Magento 2.

You can create custom insert query using Magento 2 to add/create a new record in database table via ResourceConnection class.

Using the Insert query, You can add a new record to the table using direct SQL query insert() without going to model operation.

Let’s we are adding a new record in sales_order_status table, that contains two columns only status and label

namespace Path\To\Class;

use Magento\Framework\App\ResourceConnection;

class addOrderStatus {

    const ORDER_STATUS_TABLE = 'sales_order_status';
    const STATUS_FIELD = 'status';
    const STATUS_LABEL_FIELD = 'label';

     * @var ResourceConnection
    private $resourceConnection;

    public function __construct(
       ResourceConnection $resourceConnection
    ) {
       $this->resourceConnection = $resourceConnection;

    * insert Sql Query
    public function insertStatus()
      $connection  = $this->resourceConnection->getConnection();
      $tableName = $connection->getTableName(self::ORDER_STATUS_TABLE);

      $data = [
          self::STATUS_FIELD => 'pending_hold',
          self::STATUS_LABEL_FIELD => __("Pending Onhold"),

      $connection->insert(self::ORDER_STATUS_TABLE, $data);

The First argument is the table name.

The Second argument is an array of columns of table.

The output is the new row added to sales_order_status table. You can add any no. of record in any table using insert() query.
