1．“汽车用品网上商城”前台功能
【实验7-1】主页中查询汽车配件对应的SQL操纵，编写一存储过程，实现查询特定汽车配件信息的功能。
【实验7-2】操作购物车，往购物车表中添加记录，并对购物车中某一条记录作删除操作。
【实验7-3】提交订单，编写一存储过程，给定会员编号、收货人姓名、收货人地址后在订单表中生成订单信息，同时将购物车中已有的该会员的购物记录追加到订单明细表中。
代码如下:
CREATE DEFINER=`root`@`localhost` PROCEDURE `submit_order`(in scid int,in sname varchar(50),in saddr text) BEGIN declare sapid int; declare snum int; declare sprice decimal(5,2); declare sgood_price decimal(5,2); declare sweight int; declare stime datetime; declare soid int; select autoparts_apid into sapid from shopping.shoppingcart where client_cid=scid; select `number` into snum from shopping.shoppingcart where client_cid=scid; select price into sprice from autoparts where apid=sapid; select weight*snum into sweight from autoparts where apid=sapid; set sgood_price=sprice*snum; set sweight=sweight*snum; set stime=now(); insert into `order`(`status`,order_date,client_cid,goods_price,carriage_price,total_price,total_weight,`name`,telephone,address_aid,pay_type) values("已付款",stime,scid,sgood_price,0,sgood_price,sweight,sname,"13896582356",saddr,"微信支付"); select oid into soid from `order` where order_date=stime; insert into order_has_autoparts(autoparts_apid,order_oid,deal_price,`number`) values(sapid,soid,sprice,snum); END2．“汽车用品网上商城”后端功能
