Attributes

Definition

Attributes are data properties (or dimensions/measures) of a class and they can be of the following types: number, integer, date, boolean, string and class as well.

There is no keyword attribute in VKL, you just use directly the type.

Example:

A boolean attribute of the class Order.

import: [
db.postgres.movie_db.public.ORDERS
]

kb {

class Order {

...

boolean Returned {
name.en: "Returned"

sql: "${ORDERS.returned} = 'yes'"
}
}
}
