Subject [jira] Commented: (DERBY-4387) Infinite loop in PredicateList.joinClauseTransitiveClosure()
Date Fri, 04 Dec 2009 16:26:21 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12785988#action_12785988

Dag H. Wanvik commented on DERBY-4387:

Bryan, I think the indentation is correct; but my new lines use blanks rather than tabs, I
have given up
on tabs entirely lately. (I used to try to keep tabs-only files that way, but there are very
few of them left, most already have many changed lines with space indentation.)

> This sequence of statements triggers an infinite loop in PredicateList.joinClauseTransitiveClosure()
and never completes:
> create table c (a int, b int, c int);
> create table cc (aa int);
> select * from cc t1, c t2, cc t3 where t3.aa = t2.a and t3.aa = t2.b and t3.aa = t2.c;
