是否有更快的方式来编写这3个相同的查询？

Question

Is there any faster query way of rewriting these queries or by combining them?

update products
set shop = '1' 
where shop LIKE '%demo%'

update products
set shop = '2' 
where shop LIKE '%car%'

update products
set shop = '3' 
where shop LIKE '%art%'

Answer 1

update products
set shop =
case 
when shop like '%demo%' then 1
when shop like '%car%' then 2
when shop like '%art%' then 3
else shop
end
