[jira] Commented: (DERBY-1644) NPE when inserting values to a table
that has a column declared as generated by default as identity
[ http://issues.apache.org/jira/browse/DERBY-1644?page=comments#action_12449575 ]
Bryan Pendleton commented on DERBY-1644:
----------------------------------------
I think that the issue here involves mixing "default" with constant values.
Note that the quite-similar-but-not-identical statements below all work fine:
insert into t1 (c2) values (10);
insert into t1 (c2) values default;
insert into t1 (c2) values (default);
insert into t1 (c2) values 10, 20, 30;
However, this statement gets the same NPE as the one in the description:
insert into t1 (c2) values 40, 50, default;
So it appears to be that the bug involves:
- inserting multiple rows with a single INSERT statement using multiple values clauses, and
- some of the rows have numeric constant values, while others fire the identity field generator
