org.eclipse.persistence.jpa.jpql.parser.CollectionMemberDeclaration
An identification variable declared by a collection member declaration ranges over values of a collection obtained by navigation using a path expression. Such a path expression represents a navigation involving the association-fields of an entity abstract schema type. Because a path expression can be based on another path expression, the navigation can use the association-fields of related entities. An identification variable of a collection member declaration is declared using a special operator, the reserved identifier IN. The argument to the IN operator is a collection-valued path expression. The path expression evaluates to a collection type specified as a result of navigation to a collection-valued association-field of an entity abstract schema type.

BNF: collection_member_declaration ::= IN(collection_valued_path_expression) [AS] identification_variable
or
BNF: derived_collection_member_declaration ::= IN superquery_identification_variable.{single_valued_object_field.}*collection_valued_field

Example: SELECT t FROM Player p, IN (p.teams) AS t @version 2.4.2 @since 2.3 @author Pascal Filion
