Question: Find the product names that are colored 'white' but do not have unit of measurement "Handful".
Schema: create table products (product_name varchar, product_category_code varchar, color_code varchar, PRIMARY KEY (product_name)); create table ref_colors (color_code varchar, color_description varchar, PRIMARY KEY (color_code)); create table ref_product_categories (product_category_code varchar, unit_of_measure varchar, PRIMARY KEY (product_category_code))
SQL: select t1.product_name from products as t1 join ref_product_categories as t2 on t1.product_category_code = t2.product_category_code join ref_colors as t3 on t1.color_code = t3.color_code where t3.color_description = "white" and t2.unit_of_measure <> "handful"
