SelectTranslator needs to support left join
-------------------------------------------
Key: CAY-929
URL: https://issues.apache.org/cayenne/browse/CAY-929
Project: Cayenne
Issue Type: Improvement
Components: Cayenne Core Library
Reporter: Ari Maniatis
Assignee: Andrus Adamchik
appendTable() in SelectTranslator.java simply appends a list of all tables
referenced to the FROM clause. In some cases these tables should instead be
added as a join (often a left join). This code needs to allow for that
possibility. I can see some trivial ways to do this by hacking this code, but I
am not confident of how this might fit into the grand plan of EJBQL and more.
Will this code need to accommodate other more complex joins in the future (eg
is there ever a need for outer joins?)
