> 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.
