Hello,

select p.ProductId,p.CategoryId,c.parentcategoryid,c1.parentcategoryid,c2.parentcategoryid--,c3.parentcategoryid
from @Product p
inner join @Category c on p.CategoryId=c.categoryid
inner join @Category c1 on c1.CategoryId =c.parentcategoryid
inner join @Category c2 on c2.CategoryId =c1.parentcategoryid
--inner join @Category c3 on c3.CategoryId =c1.parentcategoryid

Execute the above query
You will get the exact result
