Subject [jira] Updated: (DERBY-3441) Determine and implement a proper procedure for resetting a prepared statement for reuse in a statement pool
Date Tue, 26 Feb 2008 17:06:51 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-3441:
-----------------------------------

    Attachment: derby-3441-1a-statement_reset.diff

'derby-3441-1a-statement_reset.diff' is the first draft of a reset procedure for a statement
to be reused in a statement pool. There might be some room for refactoring in am.Statement,
since the new method copies code from various other places.

Please review / comment.
I am not confident this is the best / correct way of doing it, but I can't see any errors
caused by it either. Suggestions for how to test this is also welcome (or tests :) )!

> Initial investigations indicate there are no existing suitable methods to properly reset
a prepared (or callable) statement for reuse with a statement pool.
> A full reset is too heavy weight and defeats the purpose of statement pooling, but a
proper procedure should be achievable by reusing existing pieces of code.
> Correctness is of course the most important thing.
