 2 (
 3   id int(10) unsigned not null auto_increment primary key,
 4   account_number varchar(20) not null,
 5   account_pwd varchar(10) not null,
 6   account_money double(10,2) not null,
 7   account_status int(5) not null,
 8   create_time date not null
 9 );
10 insert into account(account_number,account_pwd,
11 account_money,account_status,create_time) values
12 ('32561589654','123',3000.00,1,'2015-05-06'),
13 ('12345678910','123',6000.00,1,'2015-05-07'),
14 ('32561588568','123',4000.00,1,'2015-05-08'),
15 ('32561587596','123',5000.00,1,'2015-05-09'),
16 ('32561581235','123',7000.00,2,'2015-05-10'),
17 ('32561581459','123',9000.00,2,'2015-05-11');
18 commit;
19 select * from account;
20 
21 insert into account
22 (account_number,account_pwd,account_money,
23 account_status,create_time) 
24 values(?,?,?,?,?)

30     }
31     public Integer getId() {
32         return id;
33     }
34     public void setId(Integer id) {

63     }
64     public void setCreate_time(String createTime) {
65         create_time = createTime;
66     }
67     @Override
68     public String toString() {
69         return "Account [account_money=" + account_money + ", account_number="
70                 + account_number + ", account_pwd=" + account_pwd
71                 + ", account_status=" + account_status + ", create_time="
72                 + create_time + ", id=" + id + "]";
