聚合查詢

1.

SELECT business_id_fk,business_name, 
       IFNULL(count(orderid_customer),0) AS total, 
       IFNULL(sum(CASE WHEN order_status IN ('CRD') THEN 1 ELSE 0 
       END), 0) AS crude, 
       IFNULL(sum(CASE WHEN order_status IN ('UNA') THEN 1 ELSE 0 
       END), 0) AS unassigned, 
       IFNULL(sum(CASE WHEN order_status IN ('DEL' , 'MCP' , 'CMP') 
       THEN 1 ELSE 0 END), 0) AS delivered, 
       IFNULL(sum(CASE WHEN order_status IN ('CNL') THEN 1 ELSE 0 
       END), 0) AS cancelled, 
       IFNULL(sum(CASE WHEN order_status IN ('CAP' , 'CAD' , 'RSP' , 
       'RSD') THEN 1 ELSE 0 END), 0) AS postponed, 
       IFNULL(SUM(total), 0) AS 'Estimated_Revenue', 
       IFNULL(SUM(CASE WHEN order_status IN ('DEL' , 'MCP', 'CMP') 
       THEN total ELSE 0 END), 0) AS 'Generated_Revenue' 
       FROM view_orders where order_datetime between '2017-08-01 
       00:00:00' and '2017-10-17 23:59:59' and parent_id IS NULL 
       GROUP BY business_id_fk ORDER BY total DESC;

SELECT A.business_id_fk,A.business_name,ifnull(((A.TotalPrice/
A.TotalQuantity)*100),0) AS 'sla_adherence' FROM (SELECT 
business_id_fk,business_name, 
sum(sla_del_datetime > delivery_datetime) AS TotalPrice 
,sum(order_status in('DEL','MCP','CMP')) AS TotalQuantity 
FROM view_orders where parent_id is null and order_datetime between '2017- 
08-01 00:00:00' and '2017-10-17 23:59:59' 
GROUP BY business_id_fk) AS A; 

3.

SELECT A.business_id_fk,A.business_name,ifnull(((A.Totaldelivered/
A.Totalorders)*100),0) AS 'strike_rate' FROM (SELECT 
business_id_fk,business_name, 
sum(order_status in('DEL','MCP','CMP')) AS Totaldelivered 
, count(*) AS Totalorders 
FROM view_orders where parent_id is null and order_datetime between '2017- 
08-01 00:00:00' and '2017-10-17 23:59:59' 
GROUP BY business_id_fk) AS A; 

爲了得到這樣

像這樣：

SELECT 
    business_id_fk,business_name, 
    total, 
    crude, 
    unassigned, 
    delivered, 
    cancelled, 
    postponed, 
    Estimated_Revenue, 
    Generated_Revenue, 
    TotalPrice, 
    Totaldelivered, 
    Totalorders, 
    ifnull(((TotalPrice/TotalQuantity)*100),0) AS 'sla_adherence', 
    ifnull(((Totaldelivered/Totalorders)*100),0) AS 'strike_rate' 
FROM 
(

    SELECT 
     business_id_fk,business_name, 
     IFNULL(count(orderid_customer),0) AS total, 
     IFNULL(sum(CASE WHEN order_status IN ('CRD') THEN 1 ELSE 0 END), 0) AS crude, 
     IFNULL(sum(CASE WHEN order_status IN ('UNA') THEN 1 ELSE 0 END), 0) AS unassigned, 
     IFNULL(sum(CASE WHEN order_status IN ('DEL' , 'MCP' , 'CMP') THEN 1 ELSE 0 END), 0) AS delivered, 
     IFNULL(sum(CASE WHEN order_status IN ('CNL') THEN 1 ELSE 0 END), 0) AS cancelled, 
     IFNULL(sum(CASE WHEN order_status IN ('CAP' , 'CAD' , 'RSP' , 'RSD') THEN 1 ELSE 0 END), 0) AS postponed, 
     IFNULL(SUM(total), 0) AS 'Estimated_Revenue', 
     IFNULL(SUM(CASE WHEN order_status IN ('DEL' , 'MCP', 'CMP') THEN total ELSE 0 END), 0) AS 'Generated_Revenue', 
     sum(sla_del_datetime > delivery_datetime) AS TotalPrice, 
     sum(order_status in('DEL','MCP','CMP')) AS TotalQuantity, 
     sum(order_status in('DEL','MCP','CMP')) AS Totaldelivered, 
     count(*) AS Totalorders 
    FROM view_orders 
    where order_datetime between '2017-08-01 00:00:00' and '2017-10-17 23:59:59' 
     and parent_id IS NULL 
    GROUP BY business_id_fk 


) AS A 
ORDER BY total DESC;
