My issue

which hidden test cases

My code

-- Sample rows from 'monthly_sales' (ensuring consistency across rows)
SELECT * 
FROM monthly_sales
ORDER BY Month  -- Assuming there is a column like 'Month' to provide some order
LIMIT 5;

-- Sample rows from 'division_product_sales' (ensuring consistency across rows)
SELECT * 
FROM division_product_sales
ORDER BY Division, Product_type  -- Assuming columns like 'Division' and 'Product_type' exist
LIMIT 5;

-- Sample rows from 'product_catalog' (ensuring consistency across rows)
SELECT * 
FROM product_catalog
ORDER BY Product_type  -- Assuming there are columns like 'Product_type' or 'SKU' for better sample selection
LIMIT 5;
