按年份和季度排序後添加百分比

Question

以下查詢返回年份和季度的訂單總計。我還希望將所述值作爲總支出的百分比表示。

SELECT DATABASE() AS PURCHASING_Total_PO_Value_By_Year, 
YEAR(order_headers.created_at) AS Year, 
QUARTER(order_headers.created_at) AS Quarter, 
COUNT(DISTINCT(order_headers.id)) AS Orders, 
SUM(order_lines.accounting_total) AS Order_Total 
FROM (order_lines LEFT JOIN order_headers ON order_lines.order_header_id = order_headers.id) 
WHERE (order_headers.status LIKE 'Issued') OR (order_headers.status LIKE 'Closed') 
Group by YEAR(order_headers.created_at), QUARTER(order_headers.created_at) 

我需要採取SUM(order_lines.accounting_total) as 'TOTAL SPEND'而不應用年和四分之一過濾器。

任何指針/提示，將不勝感激。

如果你真的只是想總計的Order_Total沒有一年或季度彙總的，那麼你可以嘗試使用子查詢：

SELECT DATABASE() AS PURCHASING_Total_PO_Value_By_Year, 
    YEAR(order_headers.created_at) AS Year, 
    QUARTER(order_headers.created_at) AS Quarter, 
    COUNT(DISTINCT(order_headers.id)) AS Orders, 
    SUM(order_lines.accounting_total) AS Order_Total, 
    100 * SUM(order_lines.accounting_total)/
     (SELECT SUM(accounting_total) FROM order_lists) AS Order_Percentage 
FROM order_lines LEFT JOIN order_headers 
    ON order_lines.order_header_id = order_headers.id 
WHERE (order_headers.status LIKE 'Issued') OR (order_headers.status LIKE 'Closed') 
GROUP BY YEAR(order_headers.created_at), QUARTER(order_headers.created_at) 

我加入柱您SELECT是這個：

100 * SUM(order_lines.accounting_total)/
    (SELECT SUM(accounting_total) FROM order_lists) AS Order_Percentage
