```
DROP TABLE IF EXISTS `transactions`;
CREATE TABLE `transactions` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `purchase_date` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `transactions` (`purchase_date`) VALUES (NULL)

```

I've isolated my problem in this code. When I run it, I get the error:

> 
> [ERROR in query 3] Unknown column 'purchase\_date' in 'field list'
> 
>

Anyone an idea?
