ecshop物料库存管理

1、创建物流库存表。sql语句：

CREATE TABLE IF NOT EXISTS `emws_materials` (
`id` mediumint(8) unsigned NOT NULL auto_increment,
`name` varchar(60) NOT NULL,
`modulus` varchar(60) NOT NULL,
`stock_number` smallint(5) unsigned NOT NULL default '0',
`stock_in` smallint(5) unsigned NOT NULL default '0',
`stock_out` smallint(5) unsigned NOT NULL default '0',
`safe_day` smallint(5) unsigned NOT NULL default '0',
`intent_day` smallint(5) unsigned NOT NULL default '0',
`is_buy` tinyint(1) unsigned NOT NULL default '1',
`buy_url` varchar(60) NOT NULL,
`price` decimal(10,2) NOT NULL,
`weight` smallint(5) unsigned NOT NULL default '0',
`img` varchar(60) NOT NULL,
`desc_info` varchar(60) NOT NULL,
`remark` varchar(60) NOT NULL,
`admin_id` smallint(5) unsigned NOT NULL,
`update_time` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
