Question

我試圖將總和值移到右邊而不是底部。

目前，我有這個疑問：

SELECT 

if(product is NULL, 'Total', product) as Product, 

total_items as Total, 
SUM(total_items) as Subtotal 
FROM items 

WHERE inv = "ABC" 


GROUP BY product 
WITH ROLLUP 

的這個輸出是：

| Product  | Total | Subtotal | 
| AB   | 260  | 260   | 
| DE   | 66  | 66   | 
| Total  | 66  | 326   | 

有沒有辦法我能做到這樣？

| Product  | Total | Subtotal | 
| AB   | 260  |    | 
| DE   | 66  |    | 
|    |   | 326   | 

Answer 1

好吧，我想通了，謝謝你的所有暗示的工會。 我做了這樣的

SELECT 

product, 
total_items as Total, 
null as Total 

FROM items 

WHERE inv = "ABC" 

GROUP BY product 

UNION ALL 

SELECT null, null, Subtotal 
FROM 
( SELECT 

    if(product is NULL, 'Subtotal', product) as Product, 
    SUM(total_items) as Subtotal 

    FROM items 

    WHERE inv = "ABC" 


    GROUP BY product 
    WITH ROLLUP 
) T 
WHERE product = "Subtotal" 

輸出：

| Product  | Total | Subtotal | 
| AB   | 260  |    | 
| DE   | 66  |    | 
|    |   | 326   |

SELECT product, 
     total_items, 
     null as Subtotal 
FROM items 
WHERE inv = "ABC" 
union all 
select null, null, SUM(total_items) from items
