identifiedBy method Null safety
- dynamic identifier
Adds an equality expression for foreign key columns to a query.
A query will only return objects where the selected object's primary key is equal to identifier
.
This method may only be used on belongs-to relationships; i.e., those that have a Relate annotation.
The type of identifier
must match the primary key type of the selected object this expression is being applied to.
var q = new Query<Employee>()
..where((e) => e.manager).identifiedBy(5);
Implementation
QueryExpressionJunction<T, InstanceType> identifiedBy(dynamic identifier) {
expression = ComparisonExpression(identifier, PredicateOperator.equalTo);
return _createJunction();
}
