[jira] Commented: (DERBY-4671) Embedded driver does not work with
jbossCache
[ https://issues.apache.org/jira/browse/DERBY-4671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12869913#action_12869913 ]
Knut Anders Hatlen commented on DERBY-4671:
-------------------------------------------
The zip file contains a derby.log which shows the query that fails:
INSERT INTO jbosscache (fqn, node, parent) SELECT ?, ?, ? FROM jbosscache_D WHERE NOT EXISTS (SELECT fqn FROM jbosscache WHERE fqn = ?)
The NPE is easily reproducible in ij:
ij> create table t (x int);
0 rows inserted/updated/deleted
ij> prepare ps as 'insert into t select ? from t';
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
Preparation of the insert statement fails with a NullPointerException in Derby 10.6.1.0, whereas 10.5.3.0 and earlier versions successfully prepare and execute the query.
I'm not sure if it is intentional that the older versions allow ? in the select list, as the same select statement fails when it's not within an insert statement:
ij> prepare ps as 'select ? from t';
ERROR 42X34: There is a ? parameter in the select list. This is not allowed.
I would have expected the same result from the insert statement. Anyhow, it should not fail with a NullPointerException.
