org.eclipse.persistence.jpa.jpql.model.query.OrderByItemStateObject
An ORDER BY item must be one of the following:
1. A {@link StateFieldPathExpressionStateObject state_field_path_expression} that evaluates toan orderable state field of an entity or embeddable class abstract schema type designated in the SELECT clause by one of the following:
  - A general_identification_variable
  - A single_valued_object_path_expression
2. A {@link StateFieldPathExpressionStateObject state_field_path_expression} that evaluates tothe same state field of the same entity or embeddable abstract schema type as a {@link StateFieldPathExpressionStateObject state_field_path_expression} in the SELECT clause
3. A {@link ResultVariableStateObject result_variable} that refers to an orderable item in theSELECT clause for which the same {@link ResultVariableStateObject result_variable}has been specified. This may be the result of an aggregate_expression, a scalar_expression, or a {@link StateFieldPathExpressionStateObject state_field_path_expression} in theSELECT clause.
The keyword ASC specifies that ascending ordering be used for the associated ORDER BY item; the keyword DESC specifies that descending ordering be used. Ascending ordering is the default.
JPA 1.0:
BNF: orderby_item ::= state_field_path_expression [ ASC | DESC ]
JPA 2.0
BNF: orderby_item ::= state_field_path_expression | result_variable [ ASC | DESC ]
