Delete unused attribute values

Question

I am using the fastsimpleimport module to create my custom import. This has a setDropdownAttributes() function to automatically create needed attribute values but it does not remove unused values. Those still show up in my advanced search.

How can I search and remove unused attribute values?

I think they are stored in eav_attribute_option_value but I am not sure how to check if they are used by a product.

Answer 1

LuFFy's answer is technically incorrect as it has 3 issues:

• it will remove values for admin store view only leaving some store-views related garbage
• it will remove unused values of attributes of all entity types
• it will remove ALL values from attributes with "multiple select" type regardless if they are assigned to any products or not because they options are stored in catalog_product_entity_varchar and not catalog_product_entity_int

The query below addresses these problems:

    DELETE o, v
      FROM `eav_attribute` a
INNER JOIN `eav_attribute_option` o ON a.`attribute_id` = o.`attribute_id`
INNER JOIN `eav_attribute_option_value` v ON v.`option_id` = o.`option_id`
INNER JOIN `eav_entity_type` t ON t.`entity_type_id` = a.`entity_type_id`
 LEFT JOIN `catalog_product_entity_int` pi ON o.`option_id` = pi.`value` AND o.`attribute_id` = pi.`attribute_id`
 LEFT JOIN `catalog_product_entity_varchar` pv ON o.`option_id` = pv.`value` AND o.`attribute_id` = pv.`attribute_id`
     WHERE pi.`entity_id` IS NULL
       AND pv.`entity_id` IS NULL
       AND t.`entity_type_code` = "catalog_product"

Answer 2

delete c,b
from eav_attribute a
inner join eav_attribute_option b on a.attribute_id = b.attribute_id
inner join eav_attribute_option_value c on c.`option_id` = b.option_id
LEFT join catalog_product_entity_int pi on b.option_id=pi.value and pi.store_id=0 and b.attribute_id=pi.attribute_id
where entity_id is null
