Subject [jira] Commented: (DERBY-4355) Implement CROSS JOIN
Date Thu, 10 Sep 2009 00:11:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753337#action_12753337

Bryan Pendleton commented on DERBY-4355:
----------------------------------------

Seems like a nice feature addition, with a clean implementation, and lots of good new added
tests.

I couldn't think of any additional tests to add; thanks for taking the time to put such a
thorough set of tests together!

+1 to commit from me.

> SELECT * from t1 CROSS JOIN t2;
> as an alternative syntax to
> SELECT * FROM t1, t2; 
> This should be pretty straight forward and ease the migration of SQL code to Derby.
