Eu só quero chamar query sql direta no Magento2 como no magento1.x
Respostas:
Ao bloquear ou modelar arquivos, é necessário inicializar o recurso e chamar a conexão
isso é
protected $_resource;
e
public function __construct(
\Magento\Backend\Block\Template\Context $context,
\Magento\Framework\App\Resource $resource,
array $data = []
) {
$this->_resource = $resource;
parent::__construct($context, $data);
}
para conexão
protected function getConnection()
{
if (!$this->connection) {
$this->connection = $this->_resource->getConnection('core_write');
}
return $this->connection;
}
abaixo está um exemplo no arquivo de bloco
<?php
/**pradeep.kumarrcs67@gmail.com*/
namespace Sugarcode\Test\Block;
class Joinex extends \Magento\Framework\View\Element\Template
{
protected $_coreRegistry = null;
protected $_orderCollectionFactory = null;
protected $connection;
protected $_resource;
public function __construct(
\Magento\Backend\Block\Template\Context $context,
\Magento\Framework\Registry $registry,
\Magento\Framework\App\Resource $resource,
\Magento\Sales\Model\Resource\Order\CollectionFactory $orderCollectionFactory,
array $data = []
) {
$this->_orderCollectionFactory = $orderCollectionFactory;
$this->_coreRegistry = $registry;
$this->_resource = $resource;
parent::__construct($context, $data);
}
public function _prepareLayout()
{
return parent::_prepareLayout();
}
protected function getConnection()
{
if (!$this->connection) {
$this->connection = $this->_resource->getConnection('core_write');
}
return $this->connection;
}
public function getDirectQuery()
{
$table=$this->_resource->getTableName('catalog_product_entity');
$sku = $this->getConnection()->fetchRow('SELECT sku,entity_id FROM ' . $table);
return $sku;
}
public function getJoinLeft()
{
$orders = $this->_orderCollectionFactory->create();
$orders->getSelect()->joinLeft(
['oce' => 'customer_entity'],
"main_table.customer_id = oce.entity_id",
[
'CONCAT(oce.firstname," ", oce.lastname) as customer_name',
'oce.firstname',
'oce.lastname',
'oce.email'
]
);
//$orders->getSelect()->__toString(); $orders->printlogquery(true); exit;
return $orders;
}
}
você usou a chamada antiga para a versão beta core_write e core_read no rc é assim:
protected _resource;
public function __construct(Context $context,
\Magento\Framework\App\ResourceConnection $resource)
{
$this->_resource = $resource;
parent::__construct($context);
}
obter adaptador:
$connection = $this->_resource->getConnection(\Magento\Framework\App\ResourceConnection::DEFAULT_CONNECTION);
obter tabela e selecione:
$tblSalesOrder = $connection->getTableName('sales_order');
$result1 = $connection->fetchAll('SELECT quote_id FROM `'.$tblSalesOrder.'` WHERE entity_id='.$orderId);
curso completo a partir daqui
Eu consegui isso da seguinte maneira. Eu tenho um arquivo personalizado onde estou criando um objeto e funcionou. Verifique uma vez.
class Sample extends \Magento\Framework\App\Http implements \Magento\Framework\AppInterface
{
public function sampleMethod()
{
$connection = $this->_objectManager->create('\Magento\Framework\App\ResourceConnection');
$conn = $connection->getConnection();
$select = $conn->select()
->from(
['o' => 'catalog_category_entity_varchar']
)
->where('o.value=?', '2');
$data = $conn->fetchAll($select);
print_r($data);
}
}
Tente e deixe-me saber se funciona para você.
Nao funciona para mim :(
Aqui está o meu arquivo de bloco:
<?php
namespace Silver\Customize\Block;
use \Magento\Framework\View\Element\Template;
class Main extends Template
{
protected $connection;
protected $_resource;
public function __construct(
\Magento\Backend\Block\Template\Context $context,
\Magento\Framework\App\Resource $resource
) {
$this->_resource = $resource;
parent::__construct($context, $data);
}
protected function _prepareLayout()
{
$this->setMessage('Hello');
$this->setName($this->getRequest()->getParam('name'));
}
public function getGoodbyeMessage()
{
return 'Goodbye World';
}
protected function getConnection()
{
if (!$this->connection) {
$this->connection = $this->_resource->getConnection('core_write');
}
return $this->connection;
}
}
Eu recebo este erro: O objeto DOMDocument deve ser criado.
o que estou perdendo?
For Join Query,
protected $_objectManager;
public function __construct(
\Magento\Framework\ObjectManagerInterface $objectManager,
\Test\Vendor\Model\ResourceModel\Vendor $resourceModel
) {
$this->resourceModel = $resourceModel;
$this->_objectManager = $objectManager;
}
$collection = $this->_objectManager->create('Test\Vendor\Model\Vendor')->getCollection();
$vendor_id = 5; //get dynamic vendor id
$collection->getSelect()->join('secondTableName as s2','main_table.entity_id = s2.vendor_id', array('*'))->where("main_table.entity_id = ".$vendor_id);
Test\Vendor\Model\VendorFactory
ou Test\Vendor\Model\Vendor\Collection
.
tente este :
//for print log on custom log file.
$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/mylog.log');
$logger = new \Zend\Log\Logger();
$logger->addWriter($writer);
$logger->info('Query cron srarting...: ');
try{
$themeId=273;
$this->_resources = \Magento\Framework\App\ObjectManager::getInstance()
->get('Magento\Framework\App\ResourceConnection');
$connection= $this->_resources->getConnection();
$negotiateTable = $this->_resources->getTableName('table_name');
$sql = "Select * FROM " . $negotiateTable;//". WHERE id = " . $themeId . ";";
$result = $connection->fetchAll($sql);
foreach ($result as $item){
$logger->info('Query cron query data...: '.json_encode($item));
}
}catch (\Exception $e){
$logger->info('Query cron query data exception'.$e->getMessage());
}
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$resource = $objectManager->get('Magento\Framework\App\ResourceConnection');
$connection = $resource->getConnection();
$tableName = $resource->getTableName('table_name');
$attribute_information = "Select * FROM " . $tableName; //check for the custom attribute condition". WHERE id = " . $manufacture . ";";
// fetchOne it return the one value
$result = $connection->fetchOne($attribute_information); ?>
\Magento\Framework\App\Resource
não existe (pelo menos não no 2.1.3). Você não quer dizerResourceConnection
?
