Kathey Marsden commented on DERBY-5249:
---------------------------------------
I am not 100% sure, but I think the original duplicate row on create problem
fixed with DERBY-1854. I think the drop problem started with DERBY-3299 in
10.4.
> A table created with 10.0.2.1 with constraints cannot be dropped with 10.5
> due to NullPointerException with insane build or ASSERT FAILED Failed to find
> sharable conglomerate descriptor for index conglomerate with sane build

> Key: DERBY-5249
> URL: https://issues.apache.org/jira/browse/DERBY-5249
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.5.3.0
> Reporter: Kathey Marsden
> Assignee: Kathey Marsden
> Attachments: repro_create.sql, repro_create.sql
>
>
> In 10.0.2.1 there was some bug that caused a duplicate entry in
> sys.sysconglomerates.
> After running the attached repro_create.sql with 10.0.2.1, you will see two
> rows returned instead of one with:
> select c.constraintname, c.constraintid, cong.conglomerateid,
> cong.conglomeratename from sys.sysconglomerates cong, sys.syskeys k,
> sys.sysconstraints c where c.constraintname = 'PK_RS' and c.constraintid
> =k.constraintid and k.conglomerateid = cong.conglomerateid ;
> I am not sure what practical impact this has with 10.0 as you can still drop
> the table s.rs with that version.
> On connecting to the database with 10.5, either soft or hard upgrade with
> 10.5.3.2 - 1103924
> DROP TABLE S.RS fails with:
> Caused by: java.sql.SQLException: Java exception: 'ASSERT FAILED Failed to

> Still need to figure out the exact versions affected, when the dup row was
> fixed, and when the drop stopped working.
> To reproduce connect to a database with 10.0.2.1
> (can be accessed at http://svn.apache.org/repos/asf/db/derby/jars/10.0.2.1)
> run the attached script repro_create.sql;
> connect with the latest on the trunk or 10.5 branch
> DROP TABLE S.RS;
> The table will not drop. The work around is to drop the table with the old
> version 10.0.2.1
