EDIT: I found my mistake.

After follow this tutorial to make a basic add-on that read and writes to a database, I modified it to fit my needs. After changing some of the fields of the database (along with the primary key) in the installer.php AND in the DataWriter.php I attempted to update the add-on by exporting it and then upgrading with the XML file. This results in:

Mysqli prepare error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'UNSIGNED, PRIMARY KEY (`xbox_site_id`) ) ' at line 7

Here is a snippet of my installer.php:

protected static $table = array(
'createQuery' => 'CREATE TABLE IF NOT EXISTS `xf_xbox_verification` (
`xbox_site_id` INT ( 9 ) NOT NULL,
`xbox_gamertag` VARCHAR (15),
`xbox_veriCode` INT (6) UNSIGNED,
`xbox_xuid` VARCHAR (200),
`xbox_attempts` INT (10) UNSIGNED,
`xbox_date` VARCHAR (100) UNSIGNED,
PRIMARY KEY (`xbox_site_id`)
ENGINE = InnoDB CHARACTER SET utf8 COLLATE utf8_general_ci;',
'dropQuery' => 'DROP TABLE IF EXISTS `xf_xbox_verification`'

And the DataWriter:

protected function _getFields() {
return array(
'xf_xbox_verification' => array(
'xbox_site_id' => array(
'type' => self::TYPE_UINT, 'required' => true
'xbox_gamertag' => array(
'type' => self::TYPE_STRING, 'required' => true
'xbox_veriCode' => array(
'type' => self::TYPE_UINT, 'required' => true
'xbox_xuid' => array(
'type' => self::TYPE_STRING, 'required' => false
'xbox_attempts' => array(
'type' => self::TYPE_UINT, 'required' => false
'xbox_date' => array(
'type' => self::TYPE_STRING, 'required' => true

Can anyone tell me what I need to change or what I did wrong? Thanks.
