[jira] Updated: (DERBY-939) NullPointerException at
ResultSet.close() time for simple query using UNION and INTERSECT
[ http://issues.apache.org/jira/browse/DERBY-939?page=all ]
A B updated DERBY-939:
----------------------
Description:
If I attempt to execute the following simple query using UNION and INTERSECT, Derby will return the correct results and then, _after_ returning the results, will throw a NullPointerException. This error does *NOT* occur for Derby 10.1, hence I'm marking it as "Major" since it seems like a regression.
To reproduce:
create table t1 (i int);
create table t2 (j int);
create table t3 (a int);
ij> select i from t1 union (select j from t2 intersect select a from t3);
1
-----------
0 rows selected
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
If I add data, the query will return the correct results, but then throw the NPE.
insert into t1 values 1, 2, 3, 4, 5;
insert into t2 values 2, 4, 6, 8, 10;
insert into t3 values 2, 3, 4;
ij> select i from t1 union (select j from t2 intersect select a from t3);

ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
The embedded and client stack traces are shown below. Both suggest that the problem occurs during the close of the result set.
