sealed trait QueryResult[-In, +Out] extends Serializable

Represents the result of executing a query. It's the result type of the following methods:

1. Collecting query results into a list

val query: Query[From[Person], PeopleStatistics]] = ???

val result = query.toList

2. Printing query results into the console

val query: Query[From[Person], PeopleStatistics]] = ???

val result = query.show(truncate = false)

3. Creating predicates that could be used in other queries

def hasAdults(faculty: Faculty) =
  select[Student]
    .where(_.faculty == faculty.name)
    .exists(_.age >= 18)

select[Faculty].whereSubQuery(hasAdults)
In
