Deleting all products using SQL

Mex — Thu, 10 Mar 2016 10:08:01 +0000

To delete all product related data, use the following query:

DELETE FROM catalog_product_entity;

Due to the constraints it will delete all related data from other tables as well.

Getting products with or without custom options using SQL

Mex — Fri, 15 Jan 2016 01:22:07 +0000

To get all products that do not have custom options, simply run the following SQL query:

SELECT
  *
FROM catalog_product_entity
WHERE entity_id NOT IN (SELECT DISTINCT
    product_id
  FROM catalog_product_option);

To get all products that do have custom options, remove the “NOT” from the above query.

Solving the “Invalid backend model specified: catalog/attribute_backend_customlayoutupdate” problem

Mex — Thu, 08 Jan 2015 13:06:54 +0000

Run the following query:

SELECT
  *
FROM eav_attribute
WHERE (
`attribute_id` LIKE '%stomlayoutupdate%'
OR `entity_type_id` LIKE '%stomlayoutupdate%'
OR `attribute_code` LIKE '%stomlayoutupdate%'
OR `attribute_model` LIKE '%stomlayoutupdate%'
OR `backend_model` LIKE '%stomlayoutupdate%'
OR `backend_type` LIKE '%stomlayoutupdate%'
OR `backend_table` LIKE '%stomlayoutupdate%'
OR `frontend_model` LIKE '%stomlayoutupdate%'
OR `frontend_input` LIKE '%stomlayoutupdate%'
OR `frontend_label` LIKE '%stomlayoutupdate%'
OR `frontend_class` LIKE '%stomlayoutupdate%'
OR `source_model` LIKE '%stomlayoutupdate%'
OR `is_required` LIKE '%stomlayoutupdate%'
OR `is_user_defined` LIKE '%stomlayoutupdate%'
OR `default_value` LIKE '%stomlayoutupdate%'
OR `is_unique` LIKE '%stomlayoutupdate%'
OR `note` LIKE '%stomlayoutupdate%'
);

Remember the attribute_ids from that query and run the following query:

DELETE
  FROM eav_attribute
WHERE attribute_id IN (attribute_ids from first query);

Done!
