Subject [jira] Updated: (DERBY-2785) ij "describe" built in command cannot describe a table named "run"

Eranda Sooriyabandara updated DERBY-2785:
-----------------------------------------

    Attachment: step logs.txt

Hi Bryan,
I compare describe statement for the tables "run" and "t1" (a normal table). 
Up to runScriptGuts() method in utilMain class both are executed in same manner according
to the stack trace. So I step into code after that method. The main difference of executing
these two table was in the line 341 in utilMain class "describe run" statement throws an exception.
Here I am attaching the step log up to throw the exception. (I thought it will more helpful
than stack trace).
thanks

> 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.

> 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).
