where子句在HIVE中使用“ IN”進行子查詢

Question

我在蜂巢中使用以下查詢：

SELECT COUNT(DISTINCT INDIV_ID) FROM TABLEA 
    WHERE CAR1="BLUE" AND INDIV_ID 
    IN (SELECT DISTINCT INDIV_ID FROM TABLEA WHERE CAR2="RED" AND CAR3="WHITE")

我現在了解了帶有in子句的子查詢在Hive中不起作用。 上面查詢的目的只是為了了解在Hive子查詢中替代何處。

有人可以告訴我如何在Hive中編寫上述查詢嗎？

Answer 1

您可以使用CTE，我已經添加了“ CAR_R_W” CTE。 下面是修改后的查詢。

WITH CAR_R_W
AS (
    SELECT DISTINCT INDIV_ID
    FROM TABLEA
    WHERE CAR2 = "RED"
        AND CAR3 = "WHITE"
    )
SELECT COUNT(DISTINCT INDIV_ID)
FROM TABLEA
WHERE CAR1 = "BLUE"
    AND INDIV_ID IN (
        SELECT INDIV_ID
        FROM CAR_R_W
        );
