I can confirm the problem: sql>SELECT * FROM TABLES SAMPLE 10; GDK reported error. BATfetchjoin(tmp_5623,tmp_5613) does not hit always (|bn|=0 != 10=|l|) => can't use fetchjoin. sql> Could you please file a bug report as Lefteris suggested? Thanks!

Dear Jun Liu and others, the problem has been fixed in the Feb2013 branch. The default branch worked correctly to start with. Jun, please download from our mercurial repository the latest source for Feb2013 and recompile. Thank you. On Sun, May 12, 2013 at 8:24 PM, Stefan Manegold wrote:
