#3、初始化sql

##a、建表sql

sql_table.sql

```
/*

```
*/
```

```

```

```
/*!40101 SET SQL_MODE=''*/;
```

/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;

/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

```
/*Table structure for table `items` */
```

```
CREATE TABLE `items` (
```

```

```

```
PRIMARY KEY (`id`)
```

) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

/*Table structure for table `orderdetail` */

```
CREATE TABLE `orderdetail` (
```

```
`id` int(11) NOT NULL AUTO_INCREMENT,
```

`orders_id` int(11) NOT NULL COMMENT '订单id',

```
KEY `FK_orderdetail_1` (`orders_id`),
```

```

```

CONSTRAINT `FK_orderdetail_1` FOREIGN KEY (`orders_id`) REFERENCES `orders` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION,

) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

```

##b、初始化数据sql

sql_data.sql

```
/*
```

```
SQLyog v10.2
```

*********************************************************************

```
*/
```

```
/*!40101 SET NAMES utf8 */;
```

```
/*!40101 SET SQL_MODE=''*/;
```

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;

/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;

/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;

/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

```
/*Data for the table `items` */
```

insert  into `items`(`id`,`name`,`price`,`detail`,`pic`,`createtime`) values (1,'台式机',3000.0,'该电脑质量非常好！！！！',NULL,'2015-02-03 13:22:53'),(2,'笔记本',6000.0,'笔记本性能好，质量好！！！！！',NULL,'2015-02-09 13:22:57'),(3,'背包',200.0,'名牌背包，容量大质量好！！！！',NULL,'2015-02-06 13:23:02');

```
/*Data for the table `orderdetail` */
```

insert  into `orderdetail`(`id`,`orders_id`,`items_id`,`items_num`) values (1,3,1,1),(2,3,2,3),(3,4,3,4),(4,4,2,3);

```
/*Data for the table `orders` */
```

insert  into `orders`(`id`,`user_id`,`number`,`createtime`,`note`) values (3,1,'1000010','2015-02-04 13:22:35',NULL),(4,1,'1000011','2015-02-03 13:22:41',NULL),(5,10,'1000012','2015-02-12 16:13:23',NULL);

```
/*Data for the table `user` */
```

insert  into `user`(`id`,`username`,`birthday`,`sex`,`address`) values (1,'王五',NULL,'2',NULL),(10,'张三','2014-07-10','1','北京市'),(16,'张小明',NULL,'1','河南郑州'),(22,'陈小明',NULL,'1','河南郑州'),(24,'张三丰',NULL,'1','河南郑州'),(25,'陈小明',NULL,'1','河南郑州'),(26,'王五',NULL,NULL,NULL);

```
/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
```

/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;

/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;

/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;
