 Description  « Hide
While we currently allow joining across a single field in the FROM clause, we could also support joining across multiple fields. For example the following is supported
SELECT Object(G) FROM UserGroup G INNER JOIN G.members M

and the following is not supported
SELECT Object(G) FROM UserGroup G INNER JOIN G.members.details D

SVN trunk and branches/3.2 handle this now (core 3.2.8+, store.rdbms 3.2.7+)
