实验一
实验步骤：
1：创建数据库“shiyan2”；
2：创建数据表’s’,’p’,’j’；
3：创建数据表’spj’并设定’sno’,’pno’,’jno’三列为外键，分别关联于s表的’sno’， p表的’pno’，j表的’jno’列；
4：分别向数据表’s’,’p’,’j’,’spj’中插入数据项；
5：建立三个表S，P，J，SPJ；
6：找出所有供应商的名字和所在城市；
7：找出所有零件的名称，颜色，重量；
8：找出使用供应商S1所供应零件的工程号码；
9：找出工程项目J2使用的各种零件的名称和数量；
10：找出上海厂商供应的所有零件号码；
11：找出使用上海厂的零件的工程名称；
12：找出没有使用天津产的零件的工程号码；
13：把全部红色零件的颜色改成蓝色；
14：由S5供给J4的零件P6改为由S3供应；
15：从供应商关系中删除S2的记录，并从供应关系中删除相应的记录；
16：将（S2，J6，P4，200）插入供应情况关系中；
17：建视图并进行相关查找操作。

实验二
实验步骤：
1．运行给定的SQL命令，创建eshop1数据库；
2．查询products表中p_price（商品价格）在800以上的商品详细信息；
3．查询products表中p_quantity（商品数量）在20和50之间的商品编号、商品名称和商品数量；
4．查询orders表中各会员购买商品的总量，并以汉字列标题形式输出会员帐号，商品总额；
5．查询members表中家庭地址为“湖南”的会员详细信息；
6．查询members表中年龄大于30且性别为“男”的会员详细信息；
7．查询orders表各商品销售总量前3名的商品编号和销售总量；
8．查询orders表中购买过商品的会员帐号，要求去掉重复行；
9．查询orders表已确认、已支付和已配送的订单详细信息；
10．查询性别为“男”的会员详细信息，查询结果按月薪降序排列；
11．查询购买商品号为’0910810004’总人数；
12．查询2018年6月6日前，所有商品的订购总量，要求输出商品号和订购总量；
13．查询所有会员的平均月薪，最高月薪和最低月薪；
14．查询所有会员购买商品的种类和，要求输出会员号和商品种类和；
15．查询购买了商品号为“0910810004”的会员号和姓名，并以汉字标题显示；
16．使用简单查询家庭地址为“湖南株洲”的会员以及年龄在30岁以上的会员详细信息；
17．将members表和orders表之间的左向外联接包括所有会员的信息，包括没有购买商品的会员。
