Selecting data from a Table raises Error XN008: Query processing has been terminated due to
an error on the server
------------------------------------------------------------------------------------------------------------------

                 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
            Priority: Critical


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.
