Variable or Inner Select in Like Operator? - mysql

Question

I need to make some updates in a table and I want to update the some values based on a like statement. e.g Like '%0010030 a.jpg'
The 0010030 is an example of a product code in my database and it reaches a specific number till now.
I would like to make an for loop to make the changes of i=0010030 to the number I need, i++.
I not sure is it works but i am trying to set it like this '%Variable_Name a.jpg'
In order do it automatically.
I actually have a list of sku/ids that i need to check
Any help or ideas?
What i have:
Insert Ignore Into prefix_virtuemart_product_medias(virtuemart_product_id,virtuemart_media_id,ordering) VALUES (
(Select nprefix_virtuemart_products.virtuemart_product_id from prefix_virtuemart_products where prefix_virtuemart_products.product_sku LIKE '0010030'),
(Select prefix_virtuemart_medias.virtuemart_media_id from prefix_virtuemart_medias
where prefix_virtuemart_medias.file_url LIKE '%0010030 a.jpg' or prefix_virtuemart_medias.file_url LIKE '%0010030 A.jpg'),5);
But i need to automatically change the LIKE parameter from a column that has all of these product codes (it's the product_sku field)

I'm not sure I understand what you are having trouble with. With the following give you the results you expect?
SELECT
nprefix_virtuemart_products.virtuemart_product_id,
pvm.virtuemart_media_id,
5
FROM
prefix_virtuemart_products pvp
INNER JOIN prefix_virtuemart_medias pvm ON pvm.file_url LIKE CONCAT('%', pvp.product_sku, ' a.jpg')
OR pvm.file_url LIKE CONCAT('%', pvp.product_sku, ' A.jpg');
For this to work the subquery can only return one row, I don't know what your data looks like, so that might not be the case.
