Cedric Dandoy commented on DERBY-4672:
--------------------------------------
The test case can be simplified to
insert into t select ? from t
For example:
connection.prepareStatement("insert into a select ? from a");
The execution fails with the following exception:
java.sql.SQLException: DERBY SQL error: SQLCODE: -1, SQLSTATE: XJ001, SQLERRMC:

> NullPointerException in insert from nested select with parameter
> ----------------------------------------------------------------
>
> Key: DERBY-4672
> URL: https://issues.apache.org/jira/browse/DERBY-4672
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.0.2.1, 10.1.1.0, 10.2.2.0, 10.4.1.3, 10.5.3.0,
> 10.6.1.0, 10.7.1.1
> Reporter: Knut Anders Hatlen
> Attachments: repro.sql

>
> Compilation of this statement fails with a NullPointerException:
> insert into t select x from (select ? from t) s(x)
> It should fail, but not with a NullPointerException. The expected error is:
> ERROR 42X34: There is a ? parameter in the select list. This is not allowed.
> I found this issue when testing the fix for DERBY-4671. It is not the same
> issue, since DERBY-4671 was a regression in 10.6.1, and this issue has been
> there for a long time (I've only tested back to 10.2.2.0, but it may have
> existed even before that).
