With a RIGHT OUTER JOIN construction, the query compares each row of entity A with each row of entity B to find all pairs of rows which have an association and thus satisfy the join-predicate. If the association exists and the join-predicate is satisfied, column values for each matched pair of rows of A and B are combined into a result row. However, in contrast to the INNER JOIN construction, rows from entity B that do not match entity A, will also be returned. When columns of entity A are specified, these columns contain a null value for these rows.
The syntax is the following:
RIGHT [ OUTER ] JOIN entity_path [ ON <constraint> ]
entity_path Specifies the entity to join and the path from an earlier defined entity in the FROM clause to this entity. The path Crm.Customer/Crm.Customer_Address/Crm.Address defines a path from the earlier defined entity Crm.Customer to the new entity Crm.Address.
