Rick Hillegas created DERBY-6663:
------------------------------------
Summary: NPE when a trigger tries to insert into a table with a
foreign key
Key: DERBY-6663
URL: https://issues.apache.org/jira/browse/DERBY-6663
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.11.0.0
Reporter: Rick Hillegas
The following script shows this problem. This is a regression. It does not
occur on 10.1.1.1 or 10.10.2.0:
{noformat}
connect 'jdbc:derby:memory:db;create=true';
create table tprim1
(
keyCol int not null,
constraint tprim1 primary key( keyCol )
);
create table tref
(
refCol int,
constraint tref foreign key( refCol ) references tprim1( keyCol )
);
create table othertable( a int );
create trigger inserttrig after insert on othertable
referencing new as new
for each row
insert into tref values ( new.a );
-- causes an NPE
insert into othertable values ( 1 );
