> Select of UPPER on upshifted column in join predicate cores
> -----------------------------------------------------------
>
> Key: TRAFODION-3018
> URL: https://issues.apache.org/jira/browse/TRAFODION-3018
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Affects Versions: 2.3
> Reporter: David Wayne Birdsall
> Assignee: David Wayne Birdsall
> Priority: Major
>
> The following script reproduces the problem. First create the table and
> populate it:
> drop table if exists mytable cascade;
> create table mytable (
> val int,
> c1 char(1) upshift,
> c2 char(1)
> );
> insert into mytable values (1, 'a', 'a');
> select * from mytable;
> If we now do any of the following SELECTs, we'll get an internal error on
> release builds or a core on debug builds:
> select t1.val from mytable t1, mytable t2 where UCASE(t1.c1) = UCASE(t2.c1);
> select t1.val from mytable t1, mytable t2 where UPPER(t1.c1) = UPPER(t2.c1);
> select t1.val from mytable t1, mytable t2 where UPSHIFT(t1.c1) =
> UPSHIFT(t2.c1);
> The first several frames on the core stack trace look like:
> (gdb) bt
