Subject [jira] Updated: (DERBY-1623) Add ANSI TRIM implementation
Date Sun, 15 Apr 2007 06:06:15 GMT

     [ https://issues.apache.org/jira/browse/DERBY-1623?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew McIntyre updated DERBY-1623:
-----------------------------------

    Attachment: compile_error.jj

The compile error I mentioned in the last comment may be a JavaCC bug, attaching a simplified
grammar which reproduces the compile error mentioned in the previous comment. It takes some
effort to be able to subscribe / post to their mailing list, so it might be a few days before
I can confirm with them this is really a JavaCC bug - or, more likely, my bad grammar :-)
- and work with them on a workaround or fix.
