-------------------------------------
Summary: ExecuteSQL generates NPE on any null valued column
Key: NIFI-1049
URL: https://issues.apache.org/jira/browse/NIFI-1049
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 0.3.0
Reporter: Randy Gelhausen
I have a table defined as:
create table test (id integer not null, val1 integer, val2 integer, constraint
my_pk primary key (id));
I have two rows in the table:
0, null, 1
1, 1, 1
When ExecuteSQL runs 'select * from test' I get an NPE:
