I am trying to sort by price on a product collection query, however, it seems sorting by price is reducing the result set to 0...

Here is a working query which returns expected number of products (865)

$productCollection = $this->productCollectionFactory->create()
    ->addAttributeToSelect('*')
    ->addFieldToFilter('my_product_type', ['eq' => 383]);
die(var_dump($productCollection->count()));

By merely adding sorting, the result set is reduced to 0...

$productCollection = $this->productCollectionFactory->create()
    ->addAttributeToSelect('*')
    ->addFieldToFilter('my_product_type', ['eq' => 383])
    ->setOrder('price', 'ASC');
die(var_dump($productCollection->count()));

Reindexing does not solve the problem. It looks like some JOINs introduced by the setOrder clause are responsible for reducing the result set to 0 items.

I found this bug report, with this patch, which I've verified is on my system.

I have also tried using addAttributeToSort instead of setOrder; the result is the same.

It seems tied to filtering the product set by my custom attribute, for when I try this

$productCollection = $this->productCollectionFactory->create()
    ->addAttributeToSelect('*')
    ->setPageSize(10)
    ->setCurPage(1)
    ->setOrder('price', 'ASC');

It works as expected.

Is it something I'm doing wrong, or a bug, or perhaps something is off with my product data?

EDIT I've added the SQL from the 3 queries above. It looks like the JOIN on catalog_product_entity_int + catalog_product_index_price is what may be breaking things?

First Call: 
SELECT `e`.*, IF(at_my_product_type.value_id > 0, at_my_product_type.value, at_my_product_type_default.value) AS `my_product_type` FROM `catalog_product_entity` AS `e`
 INNER JOIN `catalog_product_entity_int` AS `at_my_product_type_default` ON (`at_my_product_type_default`.`row_id` = `e`.`row_id`) AND (`at_my_product_type_default`.`attribute_id` = '593') AND `at_my_product_type_default`.`store_id` = 0
 LEFT JOIN `catalog_product_entity_int` AS `at_my_product_type` ON (`at_my_product_type`.`row_id` = `e`.`row_id`) AND (`at_my_product_type`.`attribute_id` = '593') AND (`at_my_product_type`.`store_id` = 1) WHERE ((IF(at_my_product_type.value_id > 0, at_my_product_type.value, at_my_product_type_default.value) = '383')) AND (e.created_in <= '1547298780') AND (e.updated_in > '1547298780')

Second Call: 
SELECT `e`.*, IF(at_my_product_type.value_id > 0, at_my_product_type.value, at_my_product_type_default.value) AS `my_product_type`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price` FROM `catalog_product_entity` AS `e`
 INNER JOIN `catalog_product_entity_int` AS `at_my_product_type_default` ON (`at_my_product_type_default`.`row_id` = `e`.`row_id`) AND (`at_my_product_type_default`.`attribute_id` = '593') AND `at_my_product_type_default`.`store_id` = 0
 LEFT JOIN `catalog_product_entity_int` AS `at_my_product_type` ON (`at_my_product_type`.`row_id` = `e`.`row_id`) AND (`at_my_product_type`.`attribute_id` = '593') AND (`at_my_product_type`.`store_id` = 1)
 INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 WHERE ((IF(at_my_product_type.value_id > 0, at_my_product_type.value, at_my_product_type_default.value) = '383')) AND (e.created_in <= '1547298780') AND (e.updated_in > '1547298780') ORDER BY `price_index`.`min_price` ASC

Third Call: 
SELECT `e`.*, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price` FROM `catalog_product_entity` AS `e`
 INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 WHERE (e.created_in <= '1547298780') AND (e.updated_in > '1547298780') ORDER BY `price_index`.`min_price` DESC

  • you have tried this $collection->addAttributeToSort('price', 'ASC'); instead of ->setOrder('price', 'ASC'); – Rakesh Donga Mar 11 '19 at 16:54
  • Yes, the result is the same. – quickshiftin Mar 11 '19 at 16:56

    I would suggest to dump the SQL for your 3 variants and look at what the difference is - it seems strange, indeed, since the join of the price index table and the join of an custom attribute shouldn't interfere – HelgeB Mar 11 '19 at 16:58
  • I've added the SQL for each query in my original question. – quickshiftin Mar 11 '19 at 17:33

    The SQL statements are OK in my opinion. So, yes, it looks like all the products with my_product_type set don't have an entry in the price index table. There is something going wrong with your price indexing if you already have tried to reindex – HelgeB Mar 11 '19 at 17:50

Turns out the products were not enabled, and moreover the indexer only considers products which are enabled.

After crafting a query to bulk enable the products and rerunning the indexer, the queries work as expected.
