SelectTerm
public enum SelectTerm<D> : ExpressibleByStringLiteral, Hashable where D : DynamicObject
The SelectTerm
is passed to the Select
clause to indicate the attributes/aggregate keys to be queried.
-
Provides a
SelectTerm
to aSelect
clause for querying an entity attribute. A shorter way to do the same is to assign from the string keypath directly:let fullName = CoreStore.queryValue( From<MyPersonEntity>(), Select<String>(.attribute("fullName")), Where("employeeID", isEqualTo: 1111) )
is equivalent to:
let fullName = CoreStore.queryValue( From<MyPersonEntity>(), Select<String>("fullName"), Where("employeeID", isEqualTo: 1111) )
