[jira] Commented: (DERBY-4504) ASSERT FAILED allTableName (T) expected to be null

["Knut Anders Hatlen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-4504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796701#action_12796701 ] 

Knut Anders Hatlen commented on DERBY-4504:
-------------------------------------------

The statement is supposed to fail, but not with an assert failure. Non-debug builds handle this error correctly:

ij> select t.* from t join t on 1=1;
ERROR 42X03: Column name 'T.X' is in more than one table in the FROM list.
