I am not sure what is going on here. I even 'got code' from system but that won't give me the check mark I'm seeking. Error message reads, "Add a Category Column" although Category is already in the statement's out put. Help Please!
select case name when 'kale-smoothie' then 'smoothie' when 'banana-smoothie' then 'smoothie' when 'orange-juice' then 'drink' when 'soda' then 'drink' when 'blt' then 'sandwich' when 'grilled-cheese' then 'sandwich' when 'tikka-masala' then 'dinner' when 'chicken-parm' then 'dinner' else 'other' end as category, round(1.0 * sum(amount_paid) / (select sum(amount_paid) from order_items) * 100, 2) as pct from order_items group by 1 order by 2 desc;
