在这种情况下,你需要构造一个包含多个条件的SQL查询,比如使用AND操作符将两个商品名称作为搜索条件。以下是使用Python和SQLite示例(其他数据库语法类似):
```python
import sqlite3
# 连接到SQLite数据库
conn = sqlite3.connect('your_database.db')
cursor = conn.cursor()
# 定义查询条件
core_quartet_item = '酷睿四核'
huawei_bracelet_item = '华为手环'
# 构造SQL查询
sql_query = f"""
SELECT customerNo, orderNo, SUM(ordersum) as total_amount
FROM (
SELECT customerNo, orderNo, SUM(price * quantity) as ordersum
FROM Orders
JOIN OrderDetails ON Orders.orderId = OrderDetails.orderId
WHERE product_name = '{core_quartet_item}' OR product_name = '{huawei_bracelet_item}'
GROUP BY customerNo, orderNo
) AS subquery
GROUP BY customerNo, orderNo
HAVING COUNT(DISTINCT product_name) = 2;
"""
# 执行查询
cursor.execute(sql_query)
# 获取结果
results = cursor.fetchall()
for row in results:
customer_no, order_no, total_amount = row
print(f"客户编号:{customer_no}, 订单编号:{order_no}, 订单金额:{total_amount}")
# 关闭连接
conn.close()
```
这个查询首先筛选出购买指定商品的记录,然后按客户和订单编号分组,最后只返回那些购买了两种商品的客户。
