Convertir SQL Select en instruction Magento getCollection

Question

J'ai une requête de sélection SQL complexe que je souhaite charger en tant que collection afin d'afficher les données dans une grille personnalisée, mais je ne parviens pas à convertir la requête en instruction getCollection équivalente de Magento.

SELECT
t1.increment_id AS "Order #",
t1.created_at as "Purchased On",
t1.billing_name as "Bill to Name",
t1.shipping_name as "Ship to Name",
t1.status as "Current Status",
IFNULL(MAX(CASE WHEN t2.status = "pending" THEN t2.created_at END), '') AS "Pending at",
IFNULL(MAX(CASE WHEN t2.status = "processing" THEN t2.created_at END), '') AS "Processing at"
FROM `sales_flat_order_grid` as t1
INNER JOIN `sales_flat_order_status_history` as t2 on t1.entity_id = t2.parent_id
GROUP BY t1.increment_id
ORDER BY t1.created_at DESC

Les jointures sont faciles mais le principal problème réside dans les colonnes complexes.Veuillez suggérer comment procéder.

Answer 1

Quelque chose comme ça devrait faire le tour:

$table = Mage::getSingleton('core/resource')->getTableName('sales/order_status_history');
$collection = Mage::getResourceModel('sales/order_grid_collection');
$select = $collection
    ->getSelect()
    ->join(array('t2' => $table), 'main_table.entity_id = t2.parent_id', array())
    ->columns(array(
        "Order #" => 'increment_id',
        "Purchased On" => 'created_at',
        "Bill to Name" => 'billing_name',
        "Ship to Name" => 'shipping_name',
        "Current Status" => 'status',
    ))
    ->columns('IFNULL(MAX(CASE WHEN t2.status = "pending" THEN t2.created_at END), "") AS "Pending at"')
    ->columns('IFNULL(MAX(CASE WHEN t2.status = "processing" THEN t2.created_at END), "") AS "Processing at"')
    ->group('increment_id')
    ->order('created_at DESC');

Recherchez le niveau de catégorie dans le produit : -

SÉLECTIONNER level,category_id,product_id DEPUIS catalog_category_product,catalog_category_entity où catalog_category_entity.entity_id = catalog_category_product.category_id ORDER BY product_id,level ASC
