如何使用count（）过滤mysql查询？

Question

我正在使用这个MySQL查询获取buy_count大于3的购买频率，有人能告诉我如何在where子句中使用count（id）？我尝试使用count（id）＆gt; 3，但它不起作用。

SELECT 
    id,
    COUNT(id) AS buying_count,
    buyer_name
FROM
    c_customer_orders
GROUP BY buyer_email

Answer 1

SELECT 
    id,
    COUNT(id) AS buying_count,
    buyer_name
FROM
    c_customer_orders
GROUP BY buyer_email
HAVING buying_count > 3

Answer 2

试试这个：

    SELECT 
    id,
    COUNT(id) AS buying_count,
    buyer_name
FROM
    c_customer_orders
GROUP BY buyer_email
HAVING buying_count >= 3
