Question

I have the sql below but can not get it to work

select product_category, 
       (
        select top 1 sub_category 
          from sub_categories 
         where product_category IN (keywords)
       ) as s 
  from products;

product category is Baby Gift Baskets and the keywords field is Baby Gift Baskets,Baby Gifts

basically want to get sub_category when product_category is found in the keywords list?

Answer 1

You would need to use

where ',' + keywords + ',' like '%,'+ product_category + ',%'

this would be much easier and more efficient with a normalised database structure. (Your current structure with multiple keywords in a single column violates first normal form)
