Subject [jira] Commented: (DERBY-1358) Reference Manual incorrectly says that SYSCONGLOMERATES.CONGLOMERATEID is a unique identifier for the conglomerate.
Date Thu, 19 Nov 2009 16:03:39 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12780127#action_12780127
] 

Bryan Pendleton commented on DERBY-1358:
----------------------------------------

Should we close this as "won't fix"? It sounds like the documentation describes 
the intent of the code accurately. Although there may not be a unique constraint
on the internal schema to enforce this, it sounds like we believe that CONGLOMERATEID
is the unique identifier for the conglomerate rows, and the only cases where this might
not be true are some situations where older databases were upgraded?

> CONGLOMERATEID is not a unique identifier for the SYSCONGLOMERATES and there is no unique
key defined SYSCONGLOMERATES.CONGLOMERATEID. Reference Manual -> Derby System Tables ->
SYCONGLOMERATES needs to be fixed to reflect that. Related thread on this can be found at
