Subject [jira] Commented: (DERBY-2017) Client driver can insert and commit partial data when a LOB stream throws IOException or does not match the specified length
Date Fri, 11 Jul 2008 12:38:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12612863#action_12612863
] 

Knut Anders Hatlen commented on DERBY-2017:
-------------------------------------------

No, it hasn't been rejected, but it was indicated that it might have negative impact on the
performance. One alternative is to add a product-specific code point so that we have a way
to indicate to the server that an error has happened. See "Developing Product-Unique Extensions"
in DRDA, Version 4, Volume 3, Section 2.5.5.4 for details.

> When a LOB stream throws an exception or does not match the specified length, the client
driver does not raise an exception until it has finished executing the statement. Therefore,
the statement will be executed (and possibly committed) on the server even though the client
reports that the statement failed.
