    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:
