如何從mysql中的不同狀態的同一表中選擇數據？

Question

我有一個這樣的桌子。

我想選擇隨機10非花哨suite_number 和隨機10花哨suite_number。現在我使用兩個查詢來做到這一點。 我可以做一個查詢嗎？ 如何從mysql中的不同狀態的同一表中選擇數據？

Answer 1

如何：

(SELECT suite_number 
    FROM tbl_name 
    WHERE is_fancy = 0 
ORDER BY RAND() 
    LIMIT 10 
) UNION ALL 
(SELECT suite_number 
    FROM tbl_name 
    WHERE is_fancy = 1 
ORDER BY RAND() 
    LIMIT 10) 
ORDER BY RAND() 

最後一行ORDER BY RAND()是可選的。

Answer 2

SELECT suite_number 
FROM my_table 
WHERE is_fancy = '1' 
ORDER BY RAND() 
LIMIT 10 
UNION 
SELECT suite_number 
FROM my_table 
WHERE is_fancy = '0' 
ORDER BY RAND() 
LIMIT 10
