[jira] [Commented] (CALCITE-3588) Support more operators in Join condition when convert RelNode to SqlNode

    [ https://issues.apache.org/jira/browse/CALCITE-3588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16995015#comment-16995015 ] 

Julian Hyde commented on CALCITE-3588:
--------------------------------------

Does current behavior throw an exception? If so please post the stack.

How about changing the subject to "JDBC adapter should handle join conditions containing IS TRUE, SIMILAR TO etc. when generating SQL". Concrete examples, and relevant to the SQL user.
