mysql为字段值添加或者去除前缀、后缀

添加前缀update `ecs_goods` set goods_name=concat('新中式',goods_name) where cat_id =4;

添加后缀update `ecs_goods` set goods_name=concat(goods_name,'新中式') where cat_id =4;

 

删除

update `ecs_goods`set goods_name=right(goods_name,length(goods_name)-1) where cat_id =4;

 

其中ecs_goods为表名,cat_id为分类字段名,goods_name为产品字段名
