[ http://issues.apache.org/jira/browse/DERBY-1589?page=comments#action_12434689 ] Mamta A. Satoor commented on DERBY-1589: ----------------------------------------
Bryan, you definitely look like on the right track with the dependency manager. I was just wondering though if this null pointer exception also happens outside of SQL authorization mode since "foreign key ... references..." gets implemented the same with or without SQL authorization mode. But I have a feeling it might be SQL authorization mode specific otherwise we would have probably run into this npe by now. > CREATE TABLE throws NullPointerException in Derby SQL Standard Authorization > after DROPs and REVOKES > ---------------------------------------------------------------------------------------------------- > > Key: DERBY-1589 > URL: http://issues.apache.org/jira/browse/DERBY-1589 > Project: Derby > Issue Type: Bug > Components: SQL > Affects Versions: 10.2.1.0 > Reporter: Daniel John Debrunner > Assigned To: Bryan Pendleton > Fix For: 10.2.1.0 > > > Currently, the last sql statement in following set of sql statements will > raise a null pointer exception > connect 'jdbc:derby:c:/dellater/dbmaintest2;create=true' user 'mamta1' as > mamta1; > create table t11ConstraintTest (c111 int not null, c112 int not null, primary > key (c111, c112)); > grant references on t11ConstraintTest to mamta3; > connect 'jdbc:derby:c:/dellater/dbmaintest2;create=true' user 'mamta3' as > mamta3; > drop table t31ConstraintTest; > -- the following statement should remember that it depends on REFERENCES > privilege on mamta1.t11ConstraintTest > create table t31ConstraintTest (c311 int, c312 int, foreign key(c311, c312) > references mamta1.t11ConstraintTest); > drop table t31ConstraintTest; > set connection mamta1; > -- following should revoke all the privileges granted on it > drop table t11ConstraintTest; > create table t11ConstraintTest (c111 int not null, c112 int not null, primary > key (c111, c112)); > grant references(c111) on t11ConstraintTest to mamta3; > grant references(c112) on t11ConstraintTest to PUBLIC; > --connect 'jdbc:derby:c:/dellater/dbmaintest2;create=true' user 'mamta3' as > mamta3; > set connection mamta3; > drop table t31ConstraintTest; > -- following sql should recompie itself because the earlier plan depended on > a privilege which doesn't > -- exist anymore.
