SQLite的 - 選擇基於總

Question

的百分比我有這樣的查詢：

SELECT id FROM my_table 
    WHERE ip IN (SELECT ip FROM my_table WHERE id IN (1, 2, 3, 4)) 
    GROUP BY id 
    HAVING SUM(count) >= 10 

而不是硬編碼要求總和（計數）> = 10，我希望它是總和（計數）是> =該ID的計數列的總和的10％（即沒有「WHERE IP IN ...」約束）

這是可能的這樣的查詢嗎？

Answer 1

你可以寫一個子查詢，以獲得10％：

SELECT id FROM my_table 
WHERE ip IN (SELECT ip FROM my_table WHERE id IN (1, 2, 3, 4)) 
GROUP BY id 
HAVING SUM(count) >= (SELECT 0.1 * SUM(t.count) FROM my_table t WHERE t.id = my_table.id)
