SELECT DISTINCT 不適用於 INNER JOIN 和 ORDER BY newid()

Question

我正在嘗試查詢葡萄酒和釀酒廠的數據庫，以從不同的釀酒廠獲取 4 種隨機葡萄酒。 不幸的是，我仍然在我的結果中看到一些重復的酒廠，並且在我的查詢中添加“DISTINCT”不適用於newid() function。 我也嘗試過“GROUP BY”和沒有解決方案的子查詢。 有什么建議么？

SELECT TOP(4) w.ID_Winery, w.appellation, w.delete_wine, w.Description_brief, w.wine_vintage, a.ID_Winery, a.weblogin, a.Winery, a.WebSiteUrl 
FROM Wines w
INNER JOIN Wineries a
    ON w.ID_Winery = a.ID_Winery
WHERE w.appellation = 'Lorem Ipsum'
    AND a.weblogin !=""
    AND w.delete_wine !=1
    AND a.Winery = 1
    AND a.WebSiteUrl !=""
    AND a.okWinery = "yes"
    AND w.Description_brief
        LIKE '%Lorem Ipsum%'
ORDER BY newid()

Answer 1

這應該這樣做：

SELECT TOP 4 *
FROM (
    SELECT w.ID_Winery, w.appellation, w.delete_wine, w.Description_brief, 
        w.wine_vintage, a.ID_Winery, a.weblogin, a.Winery, a.WebSiteUrl,
        row_number() over (partition by w.ID_Winery order by newid()) rn
    FROM Wines w
    INNER JOIN Wineries a
        ON w.ID_Winery = a.ID_Winery
    WHERE w.appellation = 'Lorem Ipsum'
        AND a.weblogin !=""
        AND w.delete_wine !=1
        AND a.Winery = 1
        AND a.WebSiteUrl !=""
        AND a.okWinery = "yes"
        AND w.Description_brief
            LIKE '%Lorem Ipsum%'
) t
WHERE rn=1
ORDER BY newid()

FWIW，我不喜歡按 newid 訂購。
