category {   sub_cat_id - numeric   sub_cat_name -  varchar   main_cat_id - varchar (2 characters)   main_cat_name -  varchar }  products {   pid - autoincrement   pname - varchar   category (Will be either sub_cat_id or main_cat_id) }

Products table

Could someone please help me with this??

  1. This should be the query you’re after:

    SELECT category, COUNT(*) FROM products GROUP BY category;

    I would recommend thinking about the design of your category table, as it might cause you difficulties in the future.
