麻煩與Select語句

Question

我有一個運行良好

SELECT 
    division, 
    division_name, 
    object_account, 
    account_description, 
    Sum(value) AS PreferedSpend 
FROM jde_dw.blanket_rpt 
WHERE division = 02 
AND vendor_type = 'PV' 
AND month = 07 
AND year = 2013 
GROUP BY division, division_name, object_account, account_description 
ORDER BY division 

現在我想增加一列，顯示總花費將是相同的查詢如上，但沒有在其中的vendor_type條件下選擇查詢聲明。

所以最終的查詢將顯示事業部，division_name，Object_account，ACCOUNT_DESCRIPTION，值（首選）和價值（總包括一切）

我怎樣才能做到這一點？

移動狀態裏面SUM()這樣只有匹配的行貢獻的總和：

SELECT 
    division, 
    division_name, 
    object_account, 
    account_description, 
    SUM(CASE WHEN vendor_type = 'PV' THEN value ELSE 0 END) as PreferedSpend, 
    SUM(value) AS TotalSpend 
FROM jde_dw.blanket_rpt 
WHERE division = 02 
AND month = 07 
AND year = 2013 
GROUP BY division, division_name, object_account, account_description 
ORDER BY division
