Mysql统计查询订单笔数超过15笔的上海客户的订单情况，输出客户名称，订单次数，订单总额（订单金额之和），结果按客户名升序排列。

以下是 SQL 查询语句：

SELECT
customer_name,
COUNT(order_id) AS order_count,
SUM(order_amount) AS total_amount
FROM
orders
WHERE
customer_city = '上海'
GROUP BY
customer_name
HAVING
COUNT(order_id) > 15
ORDER BY
customer_name ASC;

这个查询语句会统计上海客户的订单情况，输出客户名称、订单次数和订单总额，结果按客户名升序排列。
