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.
