获得许多送货地址一个订单号

Question

我使用4台

• 客户
• CUSTOMER_ORDER
• CUST_ORDER_LINE
• CUST_ADDRESS

我使用内部连接到链接表。 CUSTOMER通过customer_ID链接到CUSTOMER_ORDER和CUST_ADDRESS，并且CUSTOMER_ORDER_LINE通过order_ID链接到CUSTOMER_ORDER。 Order_ID不出现在CUSTOMER或CUST_ADDRESS表中。

当我运行下面的查询时，我得到了该特定客户和订单编号的所有送货地址。

例如，经销商有25个可能的送货地址，但他们一次只能将一个订单发送到一个送货地址。我的查询是为每个地址带回一个订单号码25次。任何建议都会很棒。谢谢。

SELECT DISTINCT TOP (100) PERCENT dbo.CUSTOMER_ORDER.ID, 
    dbo.CUSTOMER.NAME, 
    dbo.CUST_ORDER_LINE.PART_ID, 
    dbo.CUST_ORDER_LINE.ORDER_QTY, 
    dbo.CUSTOMER_ORDER.STATUS, 
    dbo.CUSTOMER_ORDER.SHIPTO_ID, 
    dbo.CUST_ADDRESS.NAME AS Expr1 
FROM dbo.CUSTOMER 
    INNER JOIN dbo.CUSTOMER_ORDER 
     ON dbo.CUSTOMER.ID = dbo.CUSTOMER_ORDER.CUSTOMER_ID 
    INNER JOIN dbo.CUST_ORDER_LINE 
     ON dbo.CUSTOMER_ORDER.ID = dbo.CUST_ORDER_LINE.CUST_ORDER_ID 
    INNER JOIN dbo.CUST_ADDRESS 
     ON dbo.CUSTOMER.ID = dbo.CUST_ADDRESS.CUSTOMER_ID 
WHERE  (dbo.CUSTOMER_ORDER.ORDER_DATE > '1/1/2014') 
    AND (dbo.CUSTOMER_ORDER.ID NOT LIKE 'RMA%') 
GROUP BY dbo.CUSTOMER_ORDER.ID, 
    dbo.CUSTOMER.NAME, 
    dbo.CUST_ORDER_LINE.PART_ID, 
    dbo.CUST_ORDER_LINE.ORDER_QTY, 
    dbo.CUSTOMER_ORDER.STATUS, 
    dbo.CUSTOMER_ORDER.SHIPTO_ID, 
    dbo.CUST_ADDRESS.NAME 
ORDER BY dbo.CUSTOMER_ORDER.ID

作为一个在黑暗中拍摄似乎你的查询应该是这样的。

SELECT 
    co.ID, 
    c.NAME, 
    col.PART_ID, 
    col.ORDER_QTY, 
    co.STATUS, 
    co.SHIPTO_ID, 
    ca.NAME AS Expr1 
FROM dbo.CUSTOMER c 
    INNER JOIN dbo.CUSTOMER_ORDER co ON c.ID = co.CUSTOMER_ID 
    INNER JOIN dbo.CUST_ORDER_LINE col ON co.ID = col.CUST_ORDER_ID 
    INNER JOIN dbo.CUST_ADDRESS ca ON co.SHIPTO_ID = ca.CUSTOMER_ID --this is now joining to the order table. 
WHERE co.ORDER_DATE > '2014-01-01' 
    AND co.ID NOT LIKE 'RMA%' 
GROUP BY co.ID, 
    c.NAME, 
    col.PART_ID, 
    col.ORDER_QTY, 
    co.STATUS, 
    co.SHIPTO_ID, 
    ca.NAME 
ORDER BY co.ID 

注意如何使用别名使这看起来更清洁。我还更改了字符串日期以使用通用格式。无论您的DATEFORMAT设置如何，这都可以工作。
