> 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:

> I got the following error:
