Subject [jira] [Commented] (DERBY-5793) Document new SYSCS_INVALIDATE_ALL_STATEMENTS procedure
Date Wed, 30 May 2012 19:08:24 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285924#comment-13285924
] 

Kim Haase commented on DERBY-5793:
----------------------------------

I'm assuming this new procedure is for the release after 10.9 -- is that correct?

Also, what is the syntax? I am guessing it takes no arguments, but I had better make sure.
Thanks!

> We should document the procedure that will get added as part of DERBY-5578. The new procedure
will invalidate all the stored prepared statements. When such an invalid stored prepared statement
is executed next time, it will get recompiled at that point thus generating a new plan for
it. This can be a very useful tool from support point of view, especially after upgrades.
