Question

Is there any simple way make count queries with Activate?

What I’m doing today is something like this:

transactional {    
    allWhere[NaturalPerson].size
}

However, I’m not sure if this is the right way of doing things.

Answer 1

There are two options:

all[NaturalPerson].size

query {
    (p: NaturalPerson) => where(p isNotNull) select(1)
}.size

Both has good performance, but the second one has better performance and can be used on versions after or equal 1.0-RC2.

Note that you are using allWhere without conditions. This won’t compile. Use just “all” if you don’t have conditions.
