Introspection

Subtopics

All objects in EdgeDB have a __type__ link which points to the schema type that the object is actually implementing. This can be used for introspection queries or to just add the object type information to a query. Let's fetch all media with their ids and corresponding types:

Input

Run

select Content {
  id,
  __type__: {
    name
  }
};

select Content {
  id,
  __type__: {
    name
  }
};

Output Objects

Press the 'Run' button to evaluate the input

Note that this is different from introspect as it provides run-time type information for concrete objects, whereas the introspect expression is resolving types statically. Compare this usage of introspect to the previous query:

Input

Run

select introspect Content {
  name
};

select introspect Content {
  name
};

Output Objects

Press the 'Run' button to evaluate the input
