Subject [jira] Commented: (DERBY-2785) ij "describe" built in command cannot describe a table named "run"
Date Tue, 22 Jun 2010 10:43:54 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12881160#action_12881160

Knut Anders Hatlen commented on DERBY-2785:
-------------------------------------------

I see you've already solved the NPE in ij, but I thought I'd mention the ij.exceptionTrace
property in case you need to debug similar problems later. The property makes ij print the
stack trace when it encounters an exception: http://db.apache.org/derby/docs/dev/tools/rtoolsijproprefexceptiontrace.html

> steps to duplicate:
> (attach ij to any database)
> ij> create table run (i int);
> 0 rows inserted/updated/deleted
> ij> desc run;
> ERROR 42X01: Syntax error: Encountered "desc" at line 1, column 1.
> ij> 
> I think this is a parser problem within ij where the "run" is taken as a token and that
token is not included in the definition of a tablename expression in the grammer (should be
an easy fix).
