MySQL避免重复值

我使用下面的查询列出包含4个或更多案例SKU的订单。一旦找到这些订单，我不想重复客户的电子邮件

当前输出示例：

Order ID    | customer_email    | total_cases_invoiced
5           | this@that.com     | 6
45          | email1@here.com   | 4
32          | email1@here.com   | 7
23          | email1@here.com   | 5
28          | another@email.com | 10

所需输出示例：

Order ID    | customer_email    | total_cases_invoiced
5           | this@that.com     | 6
45          | email1@here.com   | 4
28          | another@email.com | 10

当前查询：

SELECT 
    *, customer_email, SUM(qty_invoiced) AS total_cases_invoiced
FROM
    mg_sales_flat_order_item
        JOIN
    mg_sales_flat_order ON mg_sales_flat_order.entity_id = mg_sales_flat_order_item.order_id
WHERE
    (mg_sales_flat_order_item.sku LIKE '%A'
        OR mg_sales_flat_order_item.sku LIKE '%F'
        OR mg_sales_flat_order_item.sku LIKE '%B'
        OR mg_sales_flat_order_item.sku LIKE '%C'
        OR mg_sales_flat_order_item.sku LIKE '%FP'
        OR mg_sales_flat_order_item.sku LIKE '%AP')
        AND row_total != 0
GROUP BY order_id
HAVING SUM(qty_invoiced) >= 4
ORDER BY customer_email DESC

您是否尝试将您的

customer\u电子邮件

与

customer\u id

一起分组

SELECT 
    *, customer_email, SUM(qty_invoiced) AS total_cases_invoiced
FROM
    mg_sales_flat_order_item
        JOIN
    mg_sales_flat_order ON mg_sales_flat_order.entity_id = mg_sales_flat_order_item.order_id
WHERE
    (mg_sales_flat_order_item.sku LIKE '%A'
        OR mg_sales_flat_order_item.sku LIKE '%F'
        OR mg_sales_flat_order_item.sku LIKE '%B'
        OR mg_sales_flat_order_item.sku LIKE '%C'
        OR mg_sales_flat_order_item.sku LIKE '%FP'
        OR mg_sales_flat_order_item.sku LIKE '%AP')
        AND row_total != 0
GROUP BY (order_id,customer_email)
HAVING SUM(qty_invoiced) >= 4
ORDER BY customer_email DESC

您是否确定结果集中显示了哪个

订单ID

和

总案例数\u发票

值？您的“期望”输出似乎并不表示您关心，在这种情况下，我建议您将电子邮件地址放在您的select.mably副本中
