【问题描述】：

我有以下疑问：

SELECT
    customer_id,
    SUM(extended_amount) AS total_spent,
    COUNT(DISTINCT(client_web_order_number)) AS #_of_orders,
    MAX(oms_order_date) AS last_purchase_date,
    DATEDIFF(day, last_purchase_date, CAST(GETDATE() AS DATE))  AS days_since_last_purchase,
    MIN(oms_order_date) AS registration_date,
    DATEDIFF(day, registration_date, CAST(GETDATE() AS DATE)) AS days_active,
    CASE
        WHEN DATEDIFF(day, last_purchase_date, CAST(GETDATE() AS DATE)) = DATEDIFF(day, registration_date, CAST(GETDATE() AS DATE)) 
        THEN 'One-time purchase'
        ELSE ''
    END AS notes

FROM 
    [us_raw].[l_dmw_order_report]

WHERE 
    quantity_ordered > 0
    AND customer_id IS NOT NULL
    AND customer_id != ('')
    AND customer_id LIKE 'US%'
    AND oms_order_date IS NOT NULL
    AND UPPER(line_status) NOT IN ('','RETURN', 'CANCELLED')
    AND UPPER(item_description_1) NOT IN ('','FREIGHT', 'RETURN LABEL FEE', 'VISIBLE STITCH')
    AND (quantity_ordered * unit_price_amount) > 0
    AND extended_amount < 1000 --NO BULK ORDERS
    AND oms_order_date BETWEEN '2018-01-01' AND GETDATE()
    AND SUBSTRING(upc,1,6) IN (SELECT item_code FROM item_master_zs WHERE new_division BETWEEN '11' AND '39')

GROUP BY
    customer_id
--HAVING
--  SUM(extended_amount) BETWEEN 1 AND 50

它一直告诉我“无效的对象名称”。 该表存在。 我检查了下拉菜单以确保连接了正确的数据库。 我刷新了 Intellisense 缓存。

不知道还能做什么......

【问题讨论】：

是运行时错误吗？

什么说无效的对象名称？

更新帖子。它在结果中。

您在错误的数据库中。看看哪里写着“主人”。

总是在查询开始时使用 。

【参考方案1】：

我认为您正在寻找链接服务器对象名称，如果是，那么您需要调用它：

<linked-server-name>.<database-name>.<schema>.<object-name>

所以，之后SELECT 声明会看起来：

SELECT <alias>.*
FROM <linked-server-name>.<database-name>.<schema>.<object-name> AS <alias>
