Description

In my flow, the PutDatabaseRecord processor handled the following create and insert statements:

mysql> CREATE TABLE users (id mediumint(9) NOT NULL AUTO_INCREMENT PRIMARY KEY, first text, last text);

mysql> INSERT INTO users (id, first, last) VALUES (1, 'Andrew', 'Lim');

But when I applied this Update:

mysql> UPDATE users SET first='Drew' where id=1;

I got the following error:
