Bryan Pendleton commented on DERBY-3230:
----------------------------------------
The change looks solid to me, Kathey. The new test failed as expected without
the
code fix, and passed as expected with the code fix applied. Thanks for the
careful
research against the different versions to figure out what changed and why; your
explanation makes good sense to me. +1 to commit.
> Selecting data from a Table raises Error XN008: Query processing has been

> Key: DERBY-3230
> URL: https://issues.apache.org/jira/browse/DERBY-3230
> Project: Derby
> Issue Type: Bug
> Components: Network Client, Network Server
> Affects Versions: 10.3.1.4
> Environment: Windows XP
> Reporter: Stefan Huber
> Assignee: Kathey Marsden

> I got a table (PCLASS) in my database where I cannot select the data via a
> simple select statement:
> - If I execute 'select * from PCLASS': XN008: Query processing has been
> terminated due to an error on the server
> - If I execute 'select * from PCLASS order by CLASSNAME': it works
> - If I add or remove only one row to/from the table: it works
> If I use the embedded driver everything works fine. But as soon as I use the
> derby network client to access the database, this problem occurs.
> This is very odd. I spent a lot of time to do some research on this behavior
> because I could not believe that the network client produces errors depending
> on the data contained in a table. But after all it looks like I managed to
> fill the table with an exact amount of data that causes this error to arise.
> To reproduce the problem download the attached file and follow these
> instructions:
> * extract test.rar to $derby.system.home$
> * start derby network server
> * start ji utility and execute the following commands:
> ** connect to database test using client driver:
> connect 'jdbc:derby://localhost/test;user=ZOL;password=zol';
> ** select content of table PCLASS
> select * from PCLASS;
> --> Error XN008: Query processing has been terminated due to an error on the
> server
> ** disconnect from database
> disconnect;
> ** shutdown database 'test'
> connect
> 'jdbc:derby://localhost/test;user=ZOL;password=zol;shutdown=true';
> ** connect to database 'test' using embedded driver:
> connect 'jdbc:derby:test;user=ZOL;password=zol';
> ** select content of table PCLASS
> select * from PCLASS;
> --> everything o.k.
