SQL 2005中的TSQL：查詢

我有3個表：Customer，CustomerTypes，CustomerCustomerTypes。 CustomerCustomerTypes基本上是Customer和CustomerTypes之間的橋樑表。SQL 2005中的TSQL：查詢

表結構：客戶：客戶ID 客戶名稱

CustomerTypes： CustomerTypeID CusctomerTypeName

CustomerCustomerTypeID 的CustomerID CustomerTypeID

示例數據：客戶：

1, ABC 
2, CBA

CustomerTypes：

1, Broadcast 
2, Banking 
3, Retailer

CustomerCustomerTypes：

1, 1 
2, 2 
2, 3

我希望能夠返回查詢如下：

ABC; "Broadcasting" 
CustomerCustomerTypes; "Banking, Retailer"

以及能夠來搜索字符串讓我們說「CustomerTypeID = 2」

將ruturned爲：

CustomerCustomerTypes; "Banking, Retailer"

我能做到這一點用遊標類型的查詢，但我只是想知道，也許有更好的方法。

謝謝

用途：

SELECT c.customername, 
     STUFF((SELECT ','+ ct.customertypename 
       FROM CUSTOMERTYPES ct 
       JOIN CUSTOMERCUSTOMERTYPES cct ON cct.customertypeid = ct.customertypeid 
       WHERE cct.customerid = C.customerid 
      GROUP BY ct.customertypename 
      FOR XML PATH('')), 1, 1, '') 
FROM CUSTOMERS c

爲了能夠搜索特定客戶類型：

SELECT c.customername, 
     STUFF(SELECT ','+ ct.customertypename 
       FROM CUSTOMERTYPES ct 
       JOIN CUSTOMERCUSTOMERTYPES cct ON cct.customertypeid = ct.customertypeid 
       WHERE cct.customerid = C.customerid 
      GROUP BY ct.customertypename 
      FOR XML PATH(''), 1, 1, '') 
FROM CUSTOMERS c 
JOIN CUSTOMERCUSTOMERTYPES cct ON cct.customertypeid = ct.customertypeid 
WHERE cct.customertypeid = @customertypeid

注意，FOR XML PATH是唯一支持2005+ – 2009-12-11 03:12:52

感謝OMG小馬。我對你的代碼進行了修改，它應該在STUFF部分的SELECT之間有一個括號。再次感謝..我知道有比光標更好的方法。 – dcpartners 2009-12-11 03:28:37

@dewacorp：對不起 - 更正。 – 2009-12-11 03:35:06

用於XML查詢的SQL Server會給你你想要的。我沒有機會檢查下面的內容，但它應該指向正確的方向。

SELECT c1.CustomerTypeId, 
     (SELECT CustomerTypeName + ',' 
      FROM CustomerTypes c2 
      WHERE c2.CustomerTypeId = c1.CustomerTypeIdId 
      ORDER BY CustomerTypeName 
      FOR XML PATH('')) AS CustomerTypess 
     FROM CustomerCustomerTypes c1 
     GROUP BY CustomerTypeId;
