existenceQuery method

ModelQuery<R> existenceQuery(
  1. ModelDefinition<Model> parent,
  2. DatabaseManager db, {
  3. required String parentTable,
})

correlated against the parent table as parentTable names it (an alias inside a self-relation subquery). The built-in relations alias their own table when it has the parent's name (categories whose children are categories); custom relations fall back to correlated.

Implementation

ModelQuery<R> existenceQuery(
  ModelDefinition<Model> parent,
  DatabaseManager db, {
  required String parentTable,
}) => correlated(parent, db);
