Subject [jira] Commented: (DERBY-4244) ALTER TABLE Sanity ASSERT in add column with autocommit off
Date Thu, 02 Jul 2009 22:49:47 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12726720#action_12726720

Bryan Pendleton commented on DERBY-4244:
----------------------------------------

Hi Eranda,

In the script which reproduces the problem, I believe it is the *third* ALTER TABLE
statement which crashes, is that correct?

What happens if you remove the first or the second ALTER TABLE statements in
the script? Does it still fail the same way?

Also, what happens if you start with the original script, but in the *third* ALTER TABLE
statement you change "c2" to "c3"? Does it still fail the same way?

> While working with Eranda on DERBY-4187, I stumbled across an apparent ALTER TABLE bug.
> Here's a script which reproduces the problem for me:
> autocommit off;
> create table t0(c1 int not null constraint p1 primary key);
> alter table t0 add column c1 int;
> alter table t0 add column c2 int not null default 0 primary key;
> alter table t0 add column c2 int not null default 0;
> The "autocommit off" is crucial; otherwise the problem does not reproduce.
> Here's the detailed assertion failure:
