Subject [jira] Commented: (DERBY-1471) Implement layer B streaming for new methods defined in JDBC4.0
Date Sun, 03 Dec 2006 21:49:22 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1471?page=comments#action_12455215 ] 
            
Bryan Pendleton commented on DERBY-1471:
----------------------------------------

May I suggest an alternate wording for the new error message? Instead of

                <text>Length of LOB was retrieved though it was unknown yet.</text>

I suggest

    <text>The length of this BLOB/CLOB is not available yet. When a BLOB or CLOB is
accessed as a stream, the length is not available until the entire stream has been processed.</text>

Also, one other question on the patch, regarding the change to o.a.d.client.am.Lob:
when will it be the case that the agent_.connection_ instance is *not* an instance
of NetConnection? Don't we always have a NetConnection instance here?

The rest of the patch looks good to me.

> JDBC 4.0 introduced new methods which take parameters for object to be sent to sever
without length information.
> For those methods, Layer B streaming is best way to implement sending object to server.
> This issue is representation of DERBY-1417 in Network Client.
