SP：隨機記錄，Fave Record，加上已知記錄，無重複

Question

感謝來自很多人的幫助，我們給出了以下代碼，它非常棒。然而，我認識到我錯過了一些重要的信息，所以在這裏轉貼（用更新後的代碼）來澄清。

下面的代碼從表5個隨機記錄以及基於在第二表中標識用戶的喜愛進一步單記錄：

CREATE PROCEDURE web.getRandomCharities 
    (
    @tmp_ID bigint --members ID 
    ) 
AS 
BEGIN 

    WITH q AS 
    (
    SELECT TOP 5 * 
    FROM TBL_CHARITIES 
    WHERE cha_Active = 'TRUE' 
      AND cha_Key != '1' 
    ORDER BY NEWID() 
    ) 
SELECT * 
FROM q 
UNION ALL 
SELECT TOP 1 * 
FROM (
    SELECT * 
    FROM TBL_CHARITIES 
    WHERE TBL_CHARITIES.cha_Key IN 
      (
      SELECT members_Favourite 
      FROM TBL_MEMBERS 
      WHERE members_Id = @tmp_ID 
      ) 
    EXCEPT 
    SELECT * 
    FROM q 
    ) tc 

END 

然而，我意識到我還需要包括記錄在那裏「cha_Key =='1'」，如果它不與上面代碼中第二個SELECT語句中返回的記錄相同。

有意義嗎？

謝謝!!!

我不能完全肯定我理解你，但我相信它是這樣的......

五隨機記錄，而不＃1 一個用戶特定的記錄 記錄＃1，如果它不是用戶的特定記錄。

如果是這樣，我認爲這確實是：

 

CREATE PROCEDURE web.getRandomCharities 
    (
    @tmp_ID bigint --members ID 
    ) 
AS 
BEGIN 
    WITH q AS 
    (
    SELECT TOP 5 * 
    FROM TBL_CHARITIES 
    WHERE cha_Active = 'TRUE' 
      AND cha_Key != '1' 
    ORDER BY NEWID() 
    ) 
SELECT * 
FROM q 
UNION ALL 
SELECT TOP 1 * 
FROM (
    SELECT * 
    FROM TBL_CHARITIES 
    WHERE TBL_CHARITIES.cha_Key IN 
      (
      SELECT members_Favourite 
      FROM TBL_MEMBERS 
      WHERE members_Id = @tmp_ID 
      ) 
    EXCEPT 
    SELECT * 
    FROM q 
    ) tc 
UNION ALL 
SELECT TOP 1 * 
FROM (
    SELECT * 
    FROM TBL_CHARITIES 
    WHERE TBL_CHARITIES.cha_Key NOT IN 
      (
      SELECT members_Favourite 
      FROM TBL_MEMBERS 
      WHERE members_Id = @tmp_ID 
      ) 
     AND (TBL_CHARITIES.cha_Key = '1') 
    EXCEPT 
    SELECT * 
    FROM q 
    ) tc 
END
