Subject [jira] [Updated] (DERBY-6803) Change Sqlca and SqlException in NetworkClient to call MessageUtils
Date Thu, 06 Aug 2015 13:35:04 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bryan Pendleton updated DERBY-6803:
-----------------------------------
    Attachment: clientChanges.diff

Attached clientChanges.diff represents the current code we've been testing.

I also adjusted the Javadoc tag in Sqlca.java to address
the Javadoc complaint following yesterday's commit for
DERBY-6802.

Note that we won't want to resolve this JIRA Issue until
we've more full addressed the sqlerrmc delimiter redundancy
exposed by that Javadoc complaint.

> Currently, the network client code is not able to access the arguments
> that are associated with a Derby exception that is returned by the engine.
> We would like to change the network client code, specifically the code
> in the Sqlca and SqlException classes, so that it uses the new MessageUtils
> class to access the exception arguments.
> We wish to take the exception arguments and associate them with the
> SqlException object, so that when the client calls the SQLExceptionFactory
> to create a SQLException to throw to the user application, it can create
> a Derby-specific subclass of that exception, when appropriate, which
> contains the arguments that the server sent to the client.
