What are the product names that are not product category code 'Herbs'?
assistant
SELECT product_name FROM products WHERE product_category_code != 'Herbs';

Show the same, but for those with unit of measurement 'Handful' instead.
assistant
SELECT t1.product_name FROM products AS t1 JOIN ref_product_categories AS t2 ON t1.product_category_code = t2.product_category_code WHERE t2.unit_of_measure = 'Handul';
human
What about the opposite condition?
assistant
SELECT t1.product_name FROM products AS t1 JOIN ref_product_categories AS t2 ON t1.product_category_code = t2.product_category_code WHERE t2.unit_of_measure != "Handul" ;
