Query for missing attribute values & group urls

[HaCos]

I have been assigning several attributes values & groups with products for a multilanguage site. We didnt set up any url for each one of them as a result there are several products that have attributes which doesnt exist in my db table ps_layered_indexable_attribute_lang_value . I have created a query that manually inserts the missing entries in that table. The reason of this post is to ask you if ps_layered_indexable_attribute_group_lang_value is 'chainned' with any other table and if any confict may occur after a INSERT query.
