獲得許多送貨地址一個訂單號

Question

我使用4臺

• 客戶
• CUSTOMER_ORDER
• CUST_ORDER_LINE
• CUST_ADDRESS

我使用內部連接到鏈接表。 CUSTOMER通過customer_ID鏈接到CUSTOMER_ORDER和CUST_ADDRESS，並且CUSTOMER_ORDER_LINE通過order_ID鏈接到CUSTOMER_ORDER。 Order_ID不出現在CUSTOMER或CUST_ADDRESS表中。

當我運行下面的查詢時，我得到了該特定客戶和訂單編號的所有送貨地址。

例如，經銷商有25個可能的送貨地址，但他們一次只能將一個訂單發送到一個送貨地址。我的查詢是爲每個地址帶回一個訂單號碼25次。任何建議都會很棒。謝謝。

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

作爲一個在黑暗中拍攝似乎你的查詢應該是這樣的。

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 

注意如何使用別名使這看起來更清潔。我還更改了字符串日期以使用通用格式。無論您的DATEFORMAT設置如何，這都可以工作。
