[jira] Commented: (DERBY-1583) With grant revoke enabled, defining
a trigger whose actions updates a table (from different schema) results in
NPE
[ http://issues.apache.org/jira/browse/DERBY-1583?page=comments#action_12430185 ]
Mamta A. Satoor commented on DERBY-1583:
----------------------------------------
Bryan Pendleton ran existing test altertable.sql with derby.database.sqlAuthorization=true and the test ran into null pointer exceptions. (email thread can be found at http://www.nabble.com/derby.database.sqlAuthorization-question----usage-error-or-bug--tf2153778.html#a5949205)
The stack trace of the first null pointer exception encountered by altertable.sql has similar code path as the stack trace encountered by this jira entry and might be related. I thought I would put this information here for someone who might look into this bug.

> While working on SQL authorization work, I ran across a test case where Derby will throw a NPE when a trigger is defined with it's action as update a table from another schema. I don't have much details on why but following is the test case. Derby is trying to put privilege requirement for a column into privilege requirements list and it expects the column's tableUUID to be not null but in this particular case, it is null.
> connect 'jdbc:derby:c:/dellater/dbmain;create=true' user 'mamta1' as mamta1;
> create table t11TriggerRevokeTest (c111 int not null primary key, c12 int);
> grant TRIGGER on t11TriggerRevokeTest to mamta2;
> create table t12TriggerRevokeTest (c121 int, c122 int, c123 int);
> grant UPDATE(c122, c121) on t12TriggerRevokeTest to mamta2;
> connect 'jdbc:derby:c:/dellater/dbmain;create=true' user 'mamta2' as mamta2;
> create trigger tr11t11 after insert on mamta1.t11TriggerRevokeTest for each statement mode db2sql
> update mamta1.t12TriggerRevokeTest set c122 = 99;
> The stack trace looks as follows
