Improvement of JPA translator join behavior ------------------------------------------- Key: TEIID-5395 URL: https://issues.jboss.org/browse/TEIID-5395 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 10.2.1 Reporter: Harold Campbell Assignee: Steven Hawkins Fix For: 11.0, 10.3.2 The behavior of the JPA connector has a number of issues regarding entity relationships. * Implicit joins (those needed to get child entity id's) are made INNER JOINS, preventing getting any rows where the value would be null. * Something odd is done with *ToMany relationships which blows up the size of resultsets. * If a parent entity and a child entity use the same name for their id property, only one gets mapped. * It's not possible to join the same entity more than once.
