Answer 1

Products table, total rows 72, Hardware 2, Electronics 13.
Example 1:
Prod_category
Hardware -> case when PRODUCTS.PROD_CATEGORY='Hardware' then count( PRODUCTS.PROD_CATEGORY) else 0 end
Electronics -> case when PRODUCTS.PROD_CATEGORY='Electronics' then count( PRODUCTS.PROD_CATEGORY) else 0 end
Total -> sum(count(1))
Result:
Prod_category----Hardware----Electronics----Total
Electronics---------------0----------------13----------72
Hardware----------------2-----------------0-----------72
Peripherals
and Accessories--------0-----------------0-----------72
Photo---------------------0-----------------0-----------72
Software/Other--------0-----------------0-----------72
Example 2:
Hardware -> sum(case when PRODUCTS.PROD_CATEGORY='Hardware' then 1 else 0 end)
Electronics -> sum(case when PRODUCTS.PROD_CATEGORY='Electronics' then 1 else 0 end)
Total -> count(PRODUCTS.PROD_CATEGORY)
Result:
Hardware----Electronics----Total
2--------------------13-------------72
