             Summary: LP Bug: 1442949 - Alter table add column returns error but columns are still added
                 Key: TRAFODION-1159
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1159
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-exe
            Reporter: Weishiun Tsai
            Assignee: Anoop Sharma
            Priority: Blocker
             Fix For: 1.1 (pre-incubation)


This is a regression introduced between the v0407 build and the r1.1.0rc0 (v0410) build.  As shown in the following example, the alter table add column statements returned errors, but a showddl and a select afterwards showed that the columns were still added.

This is reproducible on a workstation as well.  This bug report is marked as Critical only because it is a regression introduced in the past 3 days and it breaks the QA regression test suite.  Mark it as Critical makes it easier to find out which check-ins in the past 3 days had caused this and to address it right away, as opposed to marking it as High and trying to track it down months later.

-------------------------------

Here is the entire script to reproduce it:

create schema mytest;
set schema mytest;

create table a12tab2 (int1 int not null, vch2 varchar(3)) store by ( int1 );

insert into a12tab2 values (1, '111'), (2, '222');
select * from a12tab2 order by int1;

alter table a12tab2 add c3 int primary key asc;
alter table a12tab2 add c4 char(4) primary key desc;
alter table a12tab2 add c5 decimal(4,2) primary key ascending;
alter table a12tab2 add column c6 smallint primary key droppable;
showddl a12tab2;
select * from a12tab2;

drop schema mytest cascade;

-------------------------------

Here is the execution output:

>>create schema mytest;
