If I have a table with a schema like this

table(Category, SubCategory1, SubCategory2, Status)

I would like to group by Category, SubCategory1 and aggregate the Status such that if not all Status values over the group have a certain value Status will be 0 otherwise 1.

So my result set will look like

(Category, SubCategory1, Status)

I don't want to write a function. I would like to do it inside the query.
