Name and version of the database you are using: MySQL 4.1
CREATE TABLE `account` (
`ACCOUNTID` int(10) unsigned NOT NULL auto_increment,
`TIMESTAMP` bigint(20) unsigned NOT NULL default '0',
`DATE` datetime default NULL,
`DESCRIPTION` char(60) NOT NULL default '',
`GAMEID` int(10) NOT NULL,
`SERVERID` int(10) NOT NULL,
PRIMARY KEY (`ACCOUNTID`)

CREATE TABLE `accountfieldmap` (
`ACCOUNTID` int(10) unsigned NOT NULL,
`FIELDID` int(10) unsigned NOT NULL,
