服装销售系统尺码库存管理实战:MySQL数据库代码实现
随着电子商务的快速发展,服装销售行业也迎来了新的机遇和挑战。如何高效地管理服装销售系统的尺码库存,成为了企业关注的焦点。本文将围绕这一主题,结合MySQL数据库,通过一系列专业代码实现服装销售系统的尺码库存管理功能。
一、系统需求分析
在服装销售系统中,尺码库存管理主要包括以下功能:
1. 尺码库存信息录入:包括尺码、颜色、数量等。
2. 尺码库存查询:根据条件查询尺码库存信息。
3. 尺码库存修改:修改尺码库存信息。
4. 尺码库存删除:删除尺码库存信息。
5. 尺码库存预警:当库存数量低于设定阈值时,系统自动预警。
二、数据库设计
为了实现上述功能,我们需要设计一个合理的数据库结构。以下是数据库设计的关键步骤:
1. 创建数据库
sql
CREATE DATABASE IF NOT EXISTS clothing_sales;
USE clothing_sales;
2. 创建尺码库存表
sql
CREATE TABLE IF NOT EXISTS size_stock (
    id INT AUTO_INCREMENT PRIMARY KEY,
    size VARCHAR(10) NOT NULL,
    color VARCHAR(20) NOT NULL,
    quantity INT NOT NULL,
    threshold INT NOT NULL
);
3. 创建用户表(可选)
sql
CREATE TABLE IF NOT EXISTS users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    password VARCHAR(50) NOT NULL
);
三、代码实现
1. 尺码库存信息录入
python
import mysql.connector
def add_size_stock(size, color, quantity, threshold):
    db = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="clothing_sales"
    )
    cursor = db.cursor()
    query = "INSERT INTO size_stock (size, color, quantity, threshold) VALUES (%s, %s, %s, %s)"
    values = (size, color, quantity, threshold)
    cursor.execute(query, values)
    db.commit()
    cursor.close()
    db.close()
 示例:添加尺码库存信息
add_size_stock("M", "Black", 100, 10)
2. 尺码库存查询
python
def query_size_stock(size=None, color=None):
    db = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="clothing_sales"
    )
    cursor = db.cursor()
    query = "SELECT  FROM size_stock WHERE 1=1"
    conditions = []
    if size:
        conditions.append("size = %s")
    if color:
        conditions.append("color = %s")
    if conditions:
        query += " AND " + " AND ".join(conditions)
    cursor.execute(query, tuple(size, color) if size and color else (size, color) if size else (color, ) if color else ())
    results = cursor.fetchall()
    cursor.close()
    db.close()
    return results
 示例:查询尺码库存信息
print(query_size_stock(size="M", color="Black"))
3. 尺码库存修改
python
def update_size_stock(id, size=None, color=None, quantity=None, threshold=None):
    db = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="clothing_sales"
    )
    cursor = db.cursor()
    query = "UPDATE size_stock SET "
    updates = []
    if size:
        updates.append("size = %s")
    if color:
        updates.append("color = %s")
    if quantity:
        updates.append("quantity = %s")
    if threshold:
        updates.append("threshold = %s")
    query += ", ".join(updates) + " WHERE id = %s"
    values = tuple(size, color, quantity, threshold, id) if size and color and quantity and threshold else (size, color, quantity, threshold, id) if size and color and quantity else (size, color, quantity, id) if size and color else (size, color, id) if size else (color, id) if color else (id, )
    cursor.execute(query, values)
    db.commit()
    cursor.close()
    db.close()
 示例:修改尺码库存信息
update_size_stock(1, size="L", color="Black", quantity=150, threshold=20)
4. 尺码库存删除
python
def delete_size_stock(id):
    db = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="clothing_sales"
    )
    cursor = db.cursor()
    query = "DELETE FROM size_stock WHERE id = %s"
    cursor.execute(query, (id,))
    db.commit()
    cursor.close()
    db.close()
 示例:删除尺码库存信息
delete_size_stock(1)
5. 尺码库存预警
python
def check_threshold():
    db = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="clothing_sales"
    )
    cursor = db.cursor()
    query = "SELECT  FROM size_stock WHERE quantity < threshold"
    cursor.execute(query)
    results = cursor.fetchall()
    cursor.close()
    db.close()
    return results
 示例:检查尺码库存预警
print(check_threshold())
四、总结
本文通过MySQL数据库和Python代码,实现了服装销售系统的尺码库存管理功能。在实际应用中,可以根据需求对代码进行扩展和优化。希望本文能对您在服装销售系统尺码库存管理方面有所帮助。
