Dag H. Wanvik commented on DERBY-3743:
--------------------------------------
I should add that derby-3743 also adds the test case
from the patch derby-3743-show-constraint-invalidate-actions
to make sure the implementation change doesn't break the
behavior.
I will commit this soon if no objections.

> The docs say that REVOKE EXECUTE ... RESTRICT should
> fail if there is a dependent constraint:
> "The RESTRICT clause specifies that the EXECUTE privilege cannot be
> revoked if the specified routine is used in a view, trigger, or
> constraint, and the privilege is being revoked from the owner of the
> view, trigger, or constraint."
> Revoking the privilege will be correctly restricted, but possibly for the
> wrong reason.
