Examples of StateFieldPathExpression

org.eclipse.persistence.jpa.internal.jpql.parser.StateFieldPathExpression
A single_valued_association_field is designated by the name of an association-field in a one-to-one or many-to-one relationship. The type of a single_valued_association_field and thus a single_valued_association_path_expression is the abstract schema type of the related entity. A collection_valued_association_field is designated by the name of an association-field in a one-to-many or a many-to-many relationship. The type of a collection_valued_association_field is a collection of values of the abstract schema type of the related entity. An embedded_class_state_field is designated by the name of an entity-state field that corresponds to an embedded class. Navigation to a related entity results in a value of the related entity's abstract schema type.

BNF: state_field_path_expression ::= {identification_variable | single_valued_association_path_expression}.state_field

BNF: single_valued_association_path_expression ::= identification_variable.{single_valued_association_field.}*single_valued_association_field
