# entities.activityDataExRelation

Read activity data ex relation records with the activityDataExRelation repository, and change them with the activity data ex relation mutations. Same records as the REST ActivityDataExRelations entity.

REST: [ActivityDataExRelations](https://developers.coevera.com/reference/rest/activity-data-ex-relations.md).

## Queries

- `getById(entityId: ID!): ActivityDataExRelationEntity` Returns the record with the given id, or null when there is none. Deleted records are returned as well.
- `getByIds(entityIds: [ID!]!): [ActivityDataExRelationEntity!]!` Returns the records with the given ids; ids without a record are left out. Deleted records are returned as well.
- `getAll(limit: Int, offset: Int, filter: ActivityDataExRelationFilterInput, orderBy: [ActivityDataExRelationOrderByInput!], includeDeleted: Boolean): [ActivityDataExRelationEntity!]!` Returns the records that match the filter, paged with limit and offset.
- `getByCriteria(filter: ActivityDataExRelationFilterInput, orderBy: [ActivityDataExRelationOrderByInput!], includeDeleted: Boolean, before: String, after: String, first: Int, last: Int): ActivityDataExRelationEntityConnection` Returns the records that match the filter as a cursor-paginated connection.
- `getChangedFieldsSinceRevision(id: UUID!, revision: Int!): [UUID!]!` Returns the ids of the fields of a record that changed after the given revision. Returns an empty list for entities without change tracking.

  entities {
    activityDataExRelation {
      getByCriteria(first: 3, orderBy: [{ modified: Desc }]) {
        totalCount
        edges { node { id modified } }
      }
    }
