Subject [jira] [Commented] (DERBY-6773) Derby throws plain SQLIntegrityConstraintViolationException
Date Fri, 27 Feb 2015 23:09:04 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14340992#comment-14340992

Bryan Pendleton commented on DERBY-6773:

Here are three things that I think would be useful to do next:

1) Prototype a change that could fix this job. I think one thing to do
    would be to change engine/org/apache/derby/impl/jdbc/SQLExceptionFactory.java
    line 85 so that it generates a different exception instance, as suggested by Jochen.

2) Modify the repro program to turn it into a test case in one of the Derby test suites.
    Perhaps the suite ConstraintCharacteristicsTest would be a good place to add
    our new test cases.

3) Study the discussion notes that occurred among the Derby Developers last year
   regarding this situation:


   Several important concerns were raised about how to address this request that 
   we should study and understand.

I think/hope that you could make headway on all of these separate courses of
action and let me/us know what you think as you study the issue in more detail.

>         Attachments: DERBY6733Repro.java
> If a unique constraint is violated by an insert statement, then Derby throws an SQLIntegrityConstraintViolationException.
The error message contains, in particular, the constraint name and the table name.
> To distinguish between cases with various constraints, Derby should instead throw a subclass
of SQLIntegrityConstraintViolationException, with methods like getConstraintName(), and getTableName().
> See also https://hibernate.atlassian.net/browse/HHH-9516.
