Question

In my DB I have the products table (ID int, … , Sponsored bool)
My goal is to be able to get 20 random products from the table. Sponsored products must be returned first. If there are less than 20 sponsored products I sould get random non sponsored products till 20 items.

Can I do this in one select? Or if not one select as efficient as possible.

Answer 1

declare @a table (ID int, Sponsored bit)

insert @a values(1, 1)
insert @a values(2, 0)
insert @a values(3, 0)

select top 20 * from @a order by sponsored desc, newid()
