Stefan Huber commented on DERBY-3230:
-------------------------------------
Sorry, but I forgot to mention that there is no error reported in the server
log file.
I tried it with the "derby.drda.debug" property set to "true" and i got pretty
much output in derby.log. But no errors or exceptions were reported.
I also tried to use the debug libraries to get more information on the error,
but there were still no error messages.
All the rows of the table are reported in derby.log. This is one of the reasons
why I believe that it could be a client problem. I used the debugger on the
client side and got to the line in method
org.apache.derby.client.net.NetCursor.checkAndThrowReceivedEndqryrm
where the exception is thrown.
At the time when the exception is thrown all data are already transferred to
the client side and it seems like there is just one byte missing for method
readFdocaOneByte (which is than calling checkAndThrowReceivedEndqryrm because
position_ == lastValidBytePosition_) but the server connection is already
closed.
I've been working with derby for a long time and i never got such a behavior.
I'm curious about an explanation for this.

> 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
> Attachments: test.rar
>
>
> 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.
