I am having trouble with the second exercise on 1.9, Grouping With Case Statements. I edited the provided code to add 'sum(amount_paid)' after the second select statement to get the percentage sales for each category. However, when I hit 'run' the editor just runs forever, or until my browser freezes. What is the problem with my code that's creating this issue?
Here's the link to the exercises: 1.9 I am stuck on the second exercise.
Here's the code just runs until my browser freezes.
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'
end as category, round(1.0 * sum(amount_paid) /
(select sum(amount_paid) from order_items) * 100, 2) as pct
group by 1
order by 2 desc;
