Using OVER() if customer has watch gladiator then 1 else 0 SQL SERVER

Question

I think I need some guidance as to what is wrong in my query. I am trying to do

Watched_Gladiator=CASE WHEN FilmName IN (CASE WHEN FilmName LIKE \'%Gladiator%\'         


        

Answer 1

Try grouping up to the cust/film level:

select
cust_nbr,
case when film_name like '%Gladiator%' then 1 else 0 end
from
(
select
    cust_nbr,
    film_name
    from
    
    group by
    cust_nbr,
    film_name
) t

Or, as an alternative:

select distinct cust_nbr
from

where 
filmname = 'Gladiator'
