. (Member Access) (Entity SQL)
The dot operator (.) is the Entity SQL member access operator. You use the member access operator to yield the value of a property or field of an instance of structural conceptual model type.
An instance of a structural conceptual model type.
A property or field that belongs to an object instance.
The dot (.) operator may be used to extract fields from a record, similar to extracting properties of a complex or entity type. For example, if n of type Name is a member of type Person, and p is an instance of type Person, then p.n is a legal member access expression that yields a value of type Name.
select p.Name.FirstName from LOB.Person as p
