ecshop点击商品分类提示数据库错误

具体如下：MySQL server error report:Array ( [0] => Array ( [message] => MySQL Query Error ) [1] => Array ( [sql] => SELECt g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, IFNULL(mp.user_price, g.shop_price * '1') AS shop_price, g.promote_price, g.goods_type, g.promote_start_date, g.promote_end_date, g.goods_brief, g.goods_thumb , g.goods_img FROM `shops`.`ecs_goods` AS g LEFT JOIN `shops`.`ecs_member_price` AS mp ON mp.goods_id = g.goods_id AND mp.user_rank = '0' WHERe g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 AND (g.cat_id IN ('1','9','6','10','7','8') OR g.goods_id IN ('') ) ORDER BY salesnum DESC LIMIT 10 ) [2] => Array ( [error] => Unknown column 'salesnum' in 'order clause' ) [3] => Array ( [errno] => 1054 ) )
请问这是什么原因？该如何解决？

数据库表缺少字段了，应该是模板加过什么插件了
