Mamta A. Satoor commented on DERBY-1538:
----------------------------------------

Welcome to Derby, Yip.

As for this particular JIRA entry, I am not sure what SQL specification says about revoking privileges from self. But I do know that, currently in Derby, if a user in general tries to revoke a permission from another user that was never granted, the revoke is a no-op and returns back silently, just like what it did for your specific example. So, what you are seeing might be expected behavior which is not mentioned in the Grant/Revoke spec. Satheesh might now the specifics.

> When revoking the owner's own privilege against the table he have created, Derby executes the revocation successfully
> but the owner is able to select from the table later as if though the REVOKE statement has no effect.  More importantly, I was expecting a SQLException with the appropriate SQLSTATE to be thrown when the owner attempts to revoke privilege from himself.  i.e.:
> ij> connect 'jdbc:derby:authtest' user 'yip' as conn1;
> ij> create table t1 (c1 int);
> 0 rows inserted/updated/deleted
> ij> insert into t1 values 1,2,3;
> 3 rows inserted/updated/deleted
> ij> revoke select on t1 from yip;
> 0 rows inserted/updated/deleted
> ij> select * from t1;
> C1
