Question

我想结合两个不同的查询并得到如下所示的结果。

此查询为我提供了取消计数w.r.t vehicle_NAME

(SELECT 'bike' "vehicle_NAME", count(B.ORDER_ID) "cancel"
FROM TABLE A, CAR_BIKE B
WHERE A.vehicle_NAME IN ('bike')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status NOT IN ('0', '00')

GROUP BY A.vehicle_NAME

union 

SELECT 'car' "vehicle_NAME", count(B.ORDER_ID) "cancel"
FROM TABLE A, CAR_BIKE B
WHERE A.vehicle_NAME IN ('car')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status NOT  IN ('0', '00')
GROUP BY A.vehicle_NAME
union 
SELECT 'cycle' "vehicle_NAME", count(B.ORDER_ID) "cancel"
FROM TABLE A, cycle_RESP B
WHERE A.vehicle_NAME IN ('cycle')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status NOT  IN ('0', '00')
GROUP BY A.vehicle_NAME)

此BELOW查询为我提供了成功交付计数w.r.t vehicle_NAME

(SELECT 'bike' "vehicle_NAME", count(B.ORDER_ID) "Delivered COUNT" 
FROM TABLE A, CAR_BIKE B
WHERE A.vehicle_NAME IN ('bike')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status IN ('0', '00')
GROUP BY A.vehicle_NAME)  
union 
SELECT 'car' "vehicle_NAME",count(B.ORDER_ID) "Delivered COUNT" 
FROM TABLE A, CAR_BIKE B
WHERE A.vehicle_NAME IN ('car')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status  IN ('0', '00')
GROUP BY A.vehicle_NAME)
union 
SELECT 'cycle' "vehicle_NAME", count(B.ORDER_ID) "Delivered COUNT" 
FROM TABLE A, cycle_RESP B
WHERE A.vehicle_NAME IN ('cycle')
AND A.ORDER_ID = B.ORDER_ID
AND B.Delivery_Status  IN ('0', '00')
GROUP BY A.vehicle_NAME)

我想结合上述两个查询并获得如下所示的输出：

vehicle_NAME | cancel | Delivered COUNT 
--------------------------------------
bike         | 20      | 35
car          | 10      | 34
cycle        | 45      | 45

Answer 1

试试这个答案：

SELECT "vehicle_NAME",SUM("cancel")"cancel",SUM("Delivered COUNT")"Delivered COUNT"
FROM(
    SELECT "vehicle_NAME","cancel",0 AS "Delivered COUNT"
    FROM
    (SELECT 'bike' "vehicle_NAME", count(B.ORDER_ID) "cancel"
    FROM TABLE A, CAR_BIKE B
    WHERE A.vehicle_NAME IN ('bike')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status NOT IN ('0', '00')
    GROUP BY A.vehicle_NAME
    union 
    SELECT 'car' "vehicle_NAME", count(B.ORDER_ID) "cancel"
    FROM TABLE A, CAR_BIKE B
    WHERE A.vehicle_NAME IN ('car')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status NOT  IN ('0', '00')
    GROUP BY A.vehicle_NAME
    union 
    SELECT 'cycle' "vehicle_NAME", count(B.ORDER_ID) "cancel"
    FROM TABLE A, cycle_RESP B
    WHERE A.vehicle_NAME IN ('cycle')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status NOT  IN ('0', '00')
    GROUP BY A.vehicle_NAME)D

    UNION ALL

    SELECT "vehicle_NAME",0 AS "cancel","Delivered COUNT"
    FROM
    (SELECT 'bike' "vehicle_NAME", count(B.ORDER_ID) "Delivered COUNT" 
    FROM TABLE A, CAR_BIKE B
    WHERE A.vehicle_NAME IN ('bike')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status IN ('0', '00')
    GROUP BY A.vehicle_NAME)  
    union 
    SELECT 'car' "vehicle_NAME",count(B.ORDER_ID) "Delivered COUNT" 
    FROM TABLE A, CAR_BIKE B
    WHERE A.vehicle_NAME IN ('car')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status  IN ('0', '00')
    GROUP BY A.vehicle_NAME)
    union 
    SELECT 'cycle' "vehicle_NAME", count(B.ORDER_ID) "Delivered COUNT" 
    FROM TABLE A, cycle_RESP B
    WHERE A.vehicle_NAME IN ('cycle')
    AND A.ORDER_ID = B.ORDER_ID
    AND B.Delivery_Status  IN ('0', '00')
    GROUP BY A.vehicle_NAME)E
    )D
GROUP BY "vehicle_NAME"

Answer 2

您似乎想要一个简单的聚合查询：

SELECT A.vehicle_NAME,
       SUM(CASE WHEN B.Delivery_Status NOT IN ('0', '00') THEN 1 ELSE 0 END) as num_cancelled,
       SUM(CASE WHEN B.Delivery_Status IN ('0', '00') THEN 1 ELSE 0 END) as num_delivered
FROM TABLE A JOIN
     CAR_BIKE B
     ON A.ORDER_ID = B.ORDER_ID
WHERE A.vehicle_NAME IN ('bike')
GROUP BY A.vehicle_NAME;

SQL：如何组合两个查询并获得相同的结果？
