4-8 실습 문의드립니다!

case when price <=5000 then 'price_group1'

when price <=10000 then 'price_group2'

when price <=30000 then 'price_group3'

when price >30000 then 'price_group4' end price_group,

case when age <30 then 'age_group1'

when age <40 then 'age_group2'

when age <50 then 'age_group3'

else 'age_group4' end age_group

조건 수식 이렇게 간단하게 해도 되나요 ?
