Colin Dean updated NIFI-5612:
-----------------------------
Description:
I'm seeing this when I execute {{SELECT * FROM <tablename>}} on a few tables
but not on dozens of others in the same database.

{code}
I don't know if I can share the database schema – still working with my team on
that – but looking at it, I think it has something to do with the signedness of
int(1) or tinyint(1) because those two are the only numerical types common to
all of the table.
*Edit 2018-09-24, so that my update doesn't get buried:*
I am able to reproduce the exception using
* Vagrant 2.1.1
* Virtualbox 5.2.18 r124319
* Ubuntu 18.04
* MySQL 5.0.81 (as close as I can get to the 5.0.80 Enterprise Edition in use
on the system where I observed this failure first)
* MySQL Connector/J 5.1.46
* NiFi 1.7.1
With this table definition and data:
{code:sql}
create table fails (
fails int(1) unsigned NOT NULL default '0'
) ENGINE=InnoDB AUTO_INCREMENT=16527 DEFAULT CHARSET=latin1;
insert into fails values ();
{code}
and an ExecuteSQL processor set up to access that table.
