[jira] [Commented] (TORQUE-7) joins should support join operators
other than equal
[ https://issues.apache.org/jira/browse/TORQUE-7?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291547#comment-13291547 ]
Thomas Fox commented on TORQUE-7:
---------------------------------
It is now possible to add composite join conditions by using the criteria.Criteria.addJoin(Strin, String, Criterion, JoinType) method.
With composite join conditions, it is not always possible to determine the joined tables from the join condition, therefore the tables to be added to the FROM clause must be specified explicitly.
Thanks to Graham Leggett for an initial patch.
