Establish an order payment table for the grocery shopping system in MySQL
Establish an order payment table for the grocery shopping system in MySQL
To establish the order payment table of the grocery shopping system in MySQL, specific code examples are required
With the development of the Internet, shopping has become more and more convenient. In the shopping process, order payment is an important part of the shopping process. The grocery shopping system not only needs to have an order generation function, but also must have a complete payment process, because only successful payment can be regarded as completing a transaction. This article will describe how to create an order payment table for the grocery shopping system in MySQL and provide specific code examples.
1. Order payment table design
The order payment table in the food shopping system stores order information. The order information includes order ID, total order amount, payment method, payment time and order status, etc. .
1. Order payment table field design
In order to better meet business needs, the order payment table should contain the following fields:
Table name: payment
Field name | Data type | Description
————|————-|——————
payment_id | int | Order payment ID, auto-increment
order_id | int | Order ID
payment_method | varchar(32) | Payment method: Alipay, WeChat, bank card, etc.
payment_amount| decimal(10,2)| Order payment amount, keep two decimal places
payment_time | datetime | Payment time
payment_status | int | Payment status: 0-unpaid, 1-paid
2. Order payment table structure example
CREATE TABLE payment (
payment_id int(11) NOT NULL AUTO_INCREMENT,
order_id int(11) NOT NULL,
payment_method varchar(32) NOT NULL,
payment_amount decimal(10,2) NOT NULL,
payment_time datetime NOT NULL,
payment_status tinyint(4) NOT NULL DEFAULT ' 0',
PRIMARY KEY (payment_id),
KEY fk_order_id (order_id),
CONSTRAINT fk_order_id FOREIGN KEY (order_id) REFERENCES order (order_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2. Code Example
When an order is generated, the field information of the order payment table needs to be updated. The following is an example of Java code to insert data into the order payment table.
/**
- Order payment service class
*
*/
@Service
public class PaymentService {
@Autowired
private PaymentMapper paymentMapper;
/**
* 插入订单支付信息
*
* @param paymentDTO 订单支付信息
* @return boolean
*/
public boolean insertPayment(PaymentDTO paymentDTO) {
Payment payment = new Payment();
payment.setOrderId(paymentDTO.getOrderId());
payment.setPaymentMethod(paymentDTO.getPaymentMethod());
payment.setPaymentAmount(paymentDTO.getPaymentAmount());
payment.setPaymentTime(paymentDTO.getPaymentTime());
payment.setPaymentStatus(paymentDTO.getPaymentStatus());
int result = paymentMapper.insertSelective(payment);
return result > 0;
}}
/**
- Order payment Mapper
*
*/
@Mapper
public interface PaymentMapper {
/** * 插入订单支付信息 * * @param payment 订单支付信息 * @return int */ int insertSelective(Payment payment);
}
/**
- Order payment entity class
*
*/
public class Payment {
/** * 订单支付ID */ private Long paymentId; /** * 订单ID */ private Long orderId; /** * 支付方式 */ private String paymentMethod; /** * 支付金额 */ private BigDecimal paymentAmount; /** * 支付时间 */ private Date paymentTime; /** * 支付状态 */ private Integer paymentStatus; // 省略getter、setter方法
}
3. Summary
When developing a grocery shopping system, the order payment table is a very important table. It records payment information for each transaction, including payment method, payment time and payment status. Through the above sample code, you can better understand how to create the order payment table of the grocery shopping system, so as to better implement the related functions of the grocery shopping system.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

How to recover data after SQL deletes rows
Apr 09, 2025 pm 12:21 PM
Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.
