Question

Querying ‘AND’ sounds simple on activate framework, the ‘,’ makes the ‘AND’ job

transactional {
    val personList2 = allWhere[NaturalPerson](_.name :== "Test", _.motherName :== "Mother")
}

I’m wondering how OR is made. An example would be nice.

Answer 1

You can use OR with allWhere. Note that you have to use parenthesis.

allWhere[NaturalPerson](p => (p.name :== "Test") :|| (p.motherName :== "Mother"))

Or you can use the complete query form:

query {
    (p: NaturalPerson) => where((p.name :== "Test") :|| (p.motherName :== "Mother")) select(p)
}
