Hello.
I read that there exists two kind of error in issue of DERBY-254 .
One is error of network and another is error of embedded.
I think I could understand to that point.
However, I'm not sure what exactly is error of embedded and what is error of
network .
Whether user uses network or embedded driver when error happens determines
which is the case ?
Or whether exception happens in network or embedded implementation deterfines
which is the case ?
//As you know, implementation of embedded ,such as engine, is used in network
mode too.
//I think this is why I feel difficluty in understanding ....
Best regards.

I'm sorry, Tomohito, can you try again. I am not able to understand
what you are asking :(

I see exception from client and exception from embed ,which are told in
your message ,was very identical in view of engine behavior .
What I see is correctly what you told ?
Best regards .

http://wiki.apache.org/db-derby/JDBC_error_messages_and_SQL_States
Hi, Tomohito. I am dealing with the null SQL states in the client
driver as part of my work on internationalizing the messages. I think
it makes a lot of sense for the SQL states to match between network
client and embedded client. I noticed, for instance, test code that
did something like:
if ( client driver is embedded )
look for SQL State NNNN
else
look for SQL State YYYY
end if
This seems silly.
What I am doing (we'll see if people have comments on this) is
defining a new severity for exceptions thrown by the network client.
Since the exception severity is mapped to the SQLException error code,
the application programmer can check the error code to determine if
it's a network client exception.
The other way they can distinguish is to see what the instance of the
class is. It will be an instance of
org.apache.derby.impl.jdbc.EmbedSQLException if it came from the
embedded driver, and an instance of
org.apache.derby.client.am.SqlException if it comes from the network
client.
I think we should keep the SQL states (and the error messages)
identical where the error is identical between the network client and
the engine.
Also, I would like to recommend that this discussion be moved to or
linked to from the JIRA issue around SQL states -- DERBY-254

SQLStates for SQLExceptions thrown from the client should not be null
and should match embedded where possible
--------------------------------------------------------------------------------------------------------------
Key: DERBY-254
URL: http://issues.apache.org/jira/browse/DERBY-254
Project: Derby
Type: Improvement
Components: Network Client
Versions: 10.2.0.0, 10.1.1.0
Reporter: Kathey Marsden
Assignee: David Van Couvering
Fix For: 10.2.0.0
SQLExceptions generated from the client tend to have a null
SQLState. An evaluation of the SQLExceptions thrown by the client
needs to be performed and match embedded where possible.
If this does not happen before the 10.1 release, it would be good to
document that SQLStates in the client will change for future releases
