部分建表和插入内容的SQL语句：
use SuperDogMall
--建立表userinfo
create tableuserinfo
( userIdvarchar(20)primary key,
userPassword varchar(20)not null,
userName varchar(20),
userEmail varchar(40),
userBirth datetime,
userAddress varchar(40),
userMoney int
)
select *from userinfo
insert intouserinfo values('zhizunbao','123','至尊宝','zhizunbao@supermall.com','1980-10-10','四川省九寨沟',50000)
insert intouserinfo values('ershixiong','123','二师兄','ershixiong@supermall.com','1981-11-14','山东省威海市',5000)
insert intouserinfo values('zixiaxianzi','123','紫霞仙子','zixiaxianzi@supermall.com','1991-11-14','四川省盘丝洞',5800)
insert intouserinfo values('niumowang','123','牛魔王','niumowang@supermall.com','1980-11-14','四川省牛头山',5100)
insert intouserinfo values('tieshan','123','铁扇公主','tieshan@supermall.com','1988-11-14','省火焰山',15000)
create tableproduct
(
proId varchar(20)primary key,
proName varchar(20),
proType varchar(20),
proPrice float check(proPrice>=0),
proStore int check(proStore>=0),
proSales int check(proSales>=0),
proPicture varchar(60),
proDesc varchar(200)
)
select *from product
insert intoproduct values('p_001','狗不理包子','食物','5','3000','1000','','好吃')
insert intoproduct values('p_002','包子','食物','2','3000','1500','','好吃')
insert into product values('p_003','德园包子','食物','1','2000','1000','','好吃')
一些driver和url的写法：
oracle
driver="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:数据库名"
sqlserver
driver="com.microsoft.jdbc.sqlserver.SQLServerDriver"
url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=数据库名"
mysql
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/数据库名?[后接参数]"
db2
driver="com.ibm.db2.jdbc.app.DB2Driver"
url="jdbc:db2://localhost:5000/数据库名"
sybase
driver="com.sybase.jdbc.SybDriver"
url="jdbc:sybase:Tds:localhost:5007/数据库名"
