> Key: DERBY-2218
> URL: https://issues.apache.org/jira/browse/DERBY-2218
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.1.3.2, 10.2.2.1, 10.2.3.0, 10.3.0.0
> Reporter: A B
> Priority: Minor
>
> If a query specifies an IN list that contains a subquery which returns an untyped NULL value, Derby will throw an NPE at bind time.
> ij> create table t1 (i int);
> 0 rows inserted/updated/deleted
> ij> select * from t1 where i in (1, 2, (values null));
> ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
> I verified the error against the latest 10.2 and 10.3 trunks; it could very well exist in earlier versions, too, but I haven't checked.
> Stack trace (from 10.2.2) is:
> java.lang.NullPointerException
