magento2 mysql update table query - mysql

Question

If someone can help with this MySQL query that would be great
I want to update this table
UPDATE catalog_product_entity_int
This query brings an array of values and works.
select catalog_product_entity.sku,catalog_product_relation.parent_id,catalog_product_flat_1.special_price
from catalog_product_entity
left join catalog_product_relation on (catalog_product_entity.entity_id = catalog_product_relation.parent_id)
left join catalog_product_flat_1 on (catalog_product_flat_1.entity_id = catalog_product_relation.child_id)
where catalog_product_entity.type_id = "configurable"
and catalog_product_flat_1.special_price > 1
GROUP BY catalog_product_relation.parent_id;
This is what I want to set based on the above query
SET catalog_product_entity_int.value = 1
where catalog_product_entity_int.attribute_id ='579'
and catalog_product_relation.parent_id = catalog_product_entity_int.entity_id
I'm not sure if I need to get the select query into a temp table first and if so how?

Answer 1

Theeasiest way is to join both table
i added aliases for he table to make it more readable
UPDATE catalog_product_entity_int t1,(select catalog_product_entity.sku,catalog_product_relation.parent_id,catalog_product_flat_1.special_price
from catalog_product_entity
left join catalog_product_relation on (catalog_product_entity.entity_id = catalog_product_relation.parent_id)
left join catalog_product_flat_1 on (catalog_product_flat_1.entity_id = catalog_product_relation.child_id)
where catalog_product_entity.type_id = "configurable"
and catalog_product_flat_1.special_price > 1
GROUP BY catalog_product_relation.parent_id) t2
SET t1.value = 1
where t1.attribute_id ='579'
and t2.parent_id = t1.entity_id
catalog_product_entity.sku and catalog_product_flat_1.special_price aren't used in the update and so you should check if they are needed
Try the select query
SELECT t1.value, t1.entity_id
FROM
catalog_product_entity_int t1 INNER JOIN (select catalog_product_entity.sku,catalog_product_relation.parent_id,catalog_product_flat_1.special_price
from catalog_product_entity
left join catalog_product_relation on (catalog_product_entity.entity_id = catalog_product_relation.parent_id)
left join catalog_product_flat_1 on (catalog_product_flat_1.entity_id = catalog_product_relation.child_id)
where catalog_product_entity.type_id = "configurable"
and catalog_product_flat_1.special_price > 1
GROUP BY catalog_product_relation.parent_id) t2
ON t2.parent_id = t1.entity_id
where t1.attribute_id ='579'

Answer 2

Thank you for the help. In the end this is what i did to make it work.
First create a temp table to store the values of the query
CREATE TABLE on_sale_updating AS
select catalog_product_entity.sku,catalog_product_relation.parent_id,catalog_product_flat_1.special_price
from catalog_product_entity
left join catalog_product_relation on (catalog_product_entity.entity_id = catalog_product_relation.parent_id)
left join catalog_product_flat_1 on (catalog_product_flat_1.entity_id = catalog_product_relation.child_id)
where catalog_product_entity.type_id = "configurable"
and catalog_product_flat_1.special_price > 1
and catalog_product_flat_1.special_to_date IS NULL OR catalog_product_flat_1.special_to_date >= CURDATE()
GROUP BY catalog_product_relation.parent_id;
Then run an update query against the temp table
update catalog_product_entity_int
inner join on_sale_updating ON catalog_product_entity_int.entity_id = on_sale_updating.parent_id
SET catalog_product_entity_int.value = 1
where catalog_product_entity_int.attribute_id ='579'
Once run for the first time add
DROP TABLE on_sale_updating;
to the first part.
